 # EnterpriseAdminExtensionAbility Development
 
-## Introduction
+## Introduction to EnterpriseAdminExtensionAbility
 
-**EnterpriseAdminExtensionAbility** is essential to a mobile device management (MDM) application. When developing an MDM application for an enterprise, you must inherit the **EnterpriseAdminExtensionAbility** class and have the MDM service logic implemented in an **EnterpriseAdminExtensionAbility** instance. The **EnterpriseAdminExtensionAbility** class provides callbacks for the enable, disable, install, and uninstall events of a device administrator application, implementing notification of system administrator status changes.
+EnterpriseAdminExtensionAbility is a mandatory component for Mobile Device Management (MDM) applications. When developing MDM applications for enterprises, you need to inherit EnterpriseAdminExtensionAbility and implement MDM service logic in the EnterpriseAdminExtensionAbility instance. EnterpriseAdminExtensionAbility implements notifications of system management status changes and defines the callbacks for when a device administrator application is enabled or disabled or an application is installed or uninstalled.
 
 ## Constraints
 
-- ***Function constraints***
+- **Function constraints**
 
-  The APIs provided can be used only by device administrator applications.
+  EnterpriseAdminExtensionAbility is applicable only to enterprise administrator applications.
   
 
-## Scenarios: Listening for the Enable, Disable, Install, and Uninstall Events of a Device Administrator Application
+## Observing Activation/Deactivation of a Device Administrator Application and Installation/Removal of an Application
 
 ### Overview
 
-**onAdminEnabled**: called when the enterprise administrator or employee deploys an MDM application and enables the DeviceAdmin permission for the application. The MDM application can set the initialization policy in the **onAdminEnabled** callback.
+**onAdminEnabled**: When an enterprise administrator or employee deploys an MDM application and activates the device administrator application, this callback is invoked to notify the MDM application that the DeviceAdmin permission is activated. The initialization policy of the MDM application can set in **onAdminEnabled**.
 
-**onAdminDisabled**: called when the system or employee disables the DeviceAdmin permission to notify the enterprise administrator that the device is no longer managed.
+**onAdminDisabled**: When the device administrator application is deactivated, the callback is invoked to notify the MDM application that the DeviceAdmin permission is deactivated.
 
-**onBundleAdded**: called to notify the enterprise administrator that the specified MDM application is installed on the device. In enterprise application administration settings, after the enterprise administrator subscribes to application installation and uninstallation events, the MDM application reports the events through the callbacks.
+**onBundleAdded**: The enterprise administrator can subscribe to application installation and uninstallation events. When an application is installed on an enterprise device, the MDM application reports the event in this callback to notify the enterprise administrator.
 
-**onBundleRemoved**: called to notify the enterprise administrator that the specified MDM application is uninstalled on the device.
+**onBundleRemoved**: When an application is removed from an enterprise device, the MDM application reports the event in this callback to notify the enterprise administrator.

-3. Open the **EnterpriseExtAbility.ts** file and import the **EnterpriseAdminExtensionAbility** module. Customize a class that inherits from **EnterpriseAdminExtensionAbility** and add the required callbacks, such as **onAdminEnabled()** and **onAdminDisabled()**, through which the enterprise administrator can receive notification when the device administrator application is enabled or disabled.
+2. Right-click the **EnterpriseExtAbility** directory, and choose **New > TypeScript File** to create a file named **EnterpriseExtAbility.ts**.
+3. Open the **EnterpriseExtAbility.ts** file and import the **EnterpriseAdminExtensionAbility** module. Inherit the **EnterpriseAdminExtensionAbility** module to the custom class and add application notification callbacks, such as **onAdminEnabled()** and **onAdminDisabled()**.

 ## How to Develop
 
-1. Import the required HTTP module.
-2. Create an **HttpRequest** object.
-3. (Optional) Listen for HTTP Response Header events.
-4. Initiate an HTTP request to a given URL.
-5. (Optional) Process the HTTP Response Header event and the return result of the HTTP request.
+1. Import the **http** namespace from **@ohos.net.http.d.ts**.
+2. Call **createHttp()** to create an **HttpRequest** object.
+3. Call **httpRequest.on()** to subscribe to HTTP response header events. This API returns a response earlier than the request. You can subscribe to HTTP response header events based on service requirements.
+4. Call **httpRequest.request()** to initiate a network request. You need to pass in the URL and optional parameters of the HTTP request.
+5. Parse the returned result based on service requirements.
+6. Call **off()** to unsubscribe from HTTP response header events.
+7. Call **httpRequest.destroy()** to release resources after the request is processed.

You can [create modules](https://developer.harmonyos.com/en/docs/documentation/doc-guides-V3/ohos-adding-deleting-module-0000001218760594-V3) in the application project in [DevEco Studio](https://developer.harmonyos.com/en/develop/deveco-studio/). As a basic functional unit of an OpenHarmony application/service, a module contains source code, resource files, third-party libraries, and application/service configuration files, and can be built and run independently. Modules can be classified as Ability or Library. A module of the Ability type is built into a Harmony Ability Package (HAP) file, and a module of the Library type is built into a [Harmony Archive (HAR)](har-package.md) file or a [Harmony Shared Package (HSP)](shared-guide.md).
   A module can contain one or more [UIAbility](../application-models/uiability-overview.md) components, as shown in the figure below.

+# Inter-Application HSP Development
+
+An inter-application Harmony Shared Package (HSP) is a file used for code and resource sharing between the host application and other applications.
+The host application of an inter-application HSP is a special form of application, which consists of only one HSP. Instead of running independently on a device, the host application runs by being referenced by dependencies of common application modules. When a common application is running, it can invoke capabilities provided by the inter-application HSP dynamically as needed.
+
+## Precautions
+1. The code of an inter-application HSP runs in the application process. When invoking the code, implement an exception capture and fault tolerance mechanism to avoid stability issues caused by malfunctioning of the inter-application HSP.
+2. An application can depend on multiple inter-application HSP files at the same time.
+3. The inter-application HSP may slow down the startup of the application that depends on it. To avoid significant increase in the startup delay, limit the number of inter-application HSP dependencies within 16.
+4. Third-party developers can only use the system-provided inter-application HSP files.
+
+## Inter-Application HSP Usage
+An inter-application HSP works by combining the following parts:
+
+[HAR](har-package.md): contains only objects and methods to be exported and therefore comes in a small size. By integrating the HAR into your application project, you can call the objects and methods therein to implement features.
+
+HSP: contains the actual implementation code, including the JS/TS code, C++ libraries, resources, and configuration files. It is either released to the application market or integrated into the system version.
+
+### Integrating the HAR in an Inter-Application HSP
+Define the interfaces to be exported in the **index.d.ets** file in the HAR, which is the entry to the declaration file exported by the inter-application HSP. The path of the **index.d.ets** file is as follows:
+```
+src
+├── main
+|    └── module.json5
+├── index.d.ets
+└── package.json
+```
+Below is an example of the **index.d.ets** file content:
+```ts
+@Component
+export declare struct UIComponent {
+  build():void;
+}
+
+export declare function hello(): string;
+
+export declare function foo1(): string;
+
+export declare function foo2(): string;
+
+export declare function nativeHello(): string;
+```
+In the example, **UIComponent** is an ArkUI component, **hello()**, **foo1()**, and **foo2()** are TS methods, and **nativeHello()** is an native method. Specific implementation is as follows:
+#### ArkUI Components
+The following is an implementation example of ArkUI components in the HSP:
+```ts
+// lib/src/main/ets/ui/MyUIComponent.ets
+@Component
+export struct UIComponent {
+  @State message: string = 'Hello World'
+  build() {
+    Column() {
+      Text(this.message)
+        .fontSize(32)
+        .padding(8)
+        .fontColor(0xffffff)
+        .backgroundColor(0x0000ff)
+    }.padding(8).width('100%')
+  }
+}
+```
+
+#### **TS Methods**
+The following is an implementation example of TS methods in the HSP:
+```ts
+export function hello(name: string): string {
+  return "hello + " + name;
+}
+
+export function foo1() {
+  return "foo1";
+}
+
+export function foo2() {
+  return "foo2";
+}
+```
+#### **Native Methods**
+The following is an implementation example of native methods in the HSP:
+```C++
+#include "napi/native_api.h"
+#include <js_native_api.h>
+#include <js_native_api_types.h>
+#include <string>
+
+const std::string libname = "liba";
+const std::string version = "v10001";
+
+static napi_value Hello(napi_env env, napi_callback_info info) {
+    napi_value ret;
+    std::string msg = libname + ":native hello, " + version;
+    napi_create_string_utf8(env, msg.c_str(), msg.length(), &ret);
+    return ret;
+}
+
+EXTERN_C_START
+static napi_value Init(napi_env env, napi_value exports) {
+    napi_property_descriptor desc[] = {
+        {"nativeHello", nullptr, Hello, nullptr, nullptr, nullptr, napi_default, nullptr}};
+    napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc);
+    return exports;
+}
+EXTERN_C_END
+
+static napi_module demoModule = {
+    .nm_version = 1,
+    .nm_flags = 0,
+    .nm_filename = nullptr,
+    .nm_register_func = Init,
+    .nm_modname = "liba",
+    .nm_priv = ((void *)0),
+    .reserved = {0},
+};
+
+extern "C" __attribute__((constructor)) void RegisterLibaModule(void) {
+    napi_module_register(&demoModule);
+}
+```
+### Using the Capabilities Exported from the HAR
+To start with, [configure dependency](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ohos-development-npm-package-0000001222578434#section89674298391) on the HAR. The dependency information will then be generated in the **module.json** file of the corresponding module, as shown in the following:
+```json
+"dependencies": [
+      {
+        "bundleName": "com.share.liba",
+        "moduleName": "liba",
+        "versionCode": 10001
+      }
+]
+```
+In the preceding information, **bundleName**, **moduleName**, and **versionCode** indicate the bundle name, module name, and version number of the inter-application HSP, respectively.
+#### Referencing ArkUI Components in the HAR
+After configuring the dependency on the HAR, you can reference ArkUI components exported from the HAR by using **import**. The sample code is as follows:
+``` ts
+import { UIComponent } from 'liba'
+
+@Entry
+@Component
+struct Index {
+  @State message: string = 'Hello World'
+  build() {
+    Row() {
+      // Reference the ArkUI component in the HAR.
+      UIComponent()
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+#### Referencing TS Classes and Methods in the HAR
+To reference the TS classes and methods exported from the HAR, use **import** as follows:
+``` ts
+import { foo1 } from 'liba'
+import { foo2 } from 'liba'
+
+@Component
+struct Index {
+  build() {
+    Row() {
+      Column() {
+        Button('Button')
+          .onClick(()=>{
+            // Reference the TS methods in the HAR.
+            foo1();
+            foo2();
+        })
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+#### Referencing Native Methods in the HAR
+To reference the native methods exported from the HAR, use **import** as follows:
+``` ts
+import { nativeHello } from 'liba'
+
+@Component
+struct Index {
+  build() {
+    Row() {
+      Column() {
+        Button('Button')
+          .onClick(()=>{
+            // Reference the native method in the HAR.
+            nativeHello();
+        })
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+
+## Inter-Application HSP Distribution
+Inter-application HSPs are not completely integrated into an application. They are distributed by being preset in the system version or installed with an application on the device. To be specific:
+1. Some frequently-used inter-application HSPs are preset in the system version.
+2. When a user downloads an application from the application market, if the application market detects that the application depends on one or more inter-application HSPs and any of these HSPs are not installed on the target device, it will download the application as well as the missing HSPs for the user. In this way, the application can use the features shared through the HSPs properly.
+
+### Inter-Application HSP Debugging Mode
+You can debug an inter-application HSP after it is distributed to a device. If the aforementioned distribution methods are not applicable, you can distribute the HSP by running **bm** commands. The procedure is as follows:
+
+> **NOTE**
+>
+> Do not reverse steps 2 and 3. Otherwise, your application will fail to be installed due to a lack of the required inter-application HSP. For more information about the **bm** commands, see [Bundle Management](../../readme/bundle-management.md).
+
+1. Obtain the inter-application HSP installation package.
+2. Run the following **bm** command to install the inter-application HSP.
+```
+bm install -s sharebundle.hsp
+```
+3. Run the following **bm** command to install the HAP file of your application.
+```
+bm install -p feature.hap
+```
+4. Start your application and start debugging.

+# HAR
+A Harmony Archive (HAR) is a static shared package that can contain code, C++ libraries, resources, and configuration files. It enables modules and projects to share code related to ArkUI components, resources, and more. Unlike a Harmony Ability Package (HAP), a HAR cannot be independently installed on a device. Instead, it can be referenced only as the dependency of an application module.
+
+## Creating a HAR Module
+You can kickstart your HAR module development with the module template of the **Library** type in DevEco Studio. By default, obfuscation is disabled for the HAR module. To enable this feature, set **artifactType** in the **build-profile.json5** file of the HAR module to **obfuscation** as follows:
+
+```json
+{
+  "apiType": "stageMode",
+  "buildOption": {
+      "artifactType": "obfuscation"
+  }
+}
+```
+The value options of **artifactType** are as follows, and the default value is **original**:
+- **original**: Code is not obfuscated.
+- **obfuscation**: Code is obfuscated using Uglify.
+
+When obfuscation is enabled, DevEco Studio compiles, obfuscates, and compresses code during HAR building, thereby protecting your code assets.
+
+> **NOTE**
+>
+> If **artifactType** is set to **obfuscation**, **apiType** must be set to **stageMode**, because obfuscation is available only in the stage model.
+
+## Precautions for HAR Development
+- The HAR does not support the declaration of **abilities** and **extensionAbilities** in its configuration file.
+- The HAR does not support the declaration of pages in its configuration file.
+- The HAR does not support **worker** configuration under **buildOption** in the **build-profile.json5** file.
+- The HAR of the FA model and that of the stage model cannot be referenced by each other.
+- The HAR of the stage model cannot reference content in the **AppScope** folder. This is because the content in the **AppScope** folder is not packaged into the HAR during compilation and building.
+
+## Exporting ArkUI Components, APIs, and Resources of the HAR
+The **index.ets** file acts as the entry of the HAR export declaration file and is where the HAR exports APIs. This file is automatically generated by DevEco Studio by default. You can specify another file as the entry declaration file in the **main** field in the **package.json** file of the module. The code snippet is as follows:
+```json
+{
+  "main": "index.ets"
+}
+```
+### Exporting ArkUI Components
+Use **export** to export the ArkUI components. The code snippet is as follows:
+```js
+// library/src/main/ets/components/MainPage/MainPage.ets
+@Component
+export struct MainPage {
+  @State message: string = 'Hello World'
+  build() {
+    Row() {
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+In the **index.ets** file, declare the APIs that the HAR exposes to external systems. The code snippet is as follows:
+```js
+// library/index.ets
+export { MainPage } from './src/main/ets/components/MainPage/MainPage'
+```
+### Exporting TS Classes and Methods
+Use **export** to export TS classes and methods. Multiple TS classes and methods can be exported at the same time. The code snippet is as follows:
+```js
+// library/src/main/ts/test.ets
+export class Log {
+    static info(msg) {
+        console.info(msg);
+    }
+}
+
+export function func() {
+  return "har func";
+}
+
+export function func2() {
+  return "har func2";
+}
+```
+In the **index.ets** file, declare the APIs that the HAR exposes to external systems. The code snippet is as follows:
+```js
+// library/index.ets
+export { Log } from './src/main/ts/test'
+export { func } from './src/main/ts/test'
+export { func2 } from './src/main/ts/test'
+```
+### Resources
+Resources are packed into the HAR when it is being compiled and packaged. During compilation and building of a HAP, DevEco Studio collects resource files from the HAP module and its dependent modules. If the resource files of different modules have the same name, DevEco Studio overwrites the resource files based on the following priorities (in descending order):
+- AppScope (supported only by the stage model of API version 9)
+- Modules in the HAP file
+- If resource conflicts occur between dependent HAR modules, they are overwritten based on the dependency sequence. (The module that is higher in the dependency sequence list has higher priority.)
+
+## Referencing ArkUI Components, APIs, and Resources in the HAR
+To start with, [configure dependency](https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ohos-development-npm-package-0000001222578434#section89674298391) on the HAR.
+
+### Reference ArkUI Components in the HAR
+
+After configuring the dependency on the HAR, you can reference ArkUI components exported from the HAR by using **import**. The sample code is as follows:
+```js
+// entry/src/main/ets/pages/index.ets
+import { MainPage } from "@ohos/library"
+
+@Entry
+@Component
+struct Index {
+  @State message: string = 'Hello World'
+  build() {
+    Row() {
+      // Reference the ArkUI component in the HAR.
+      MainPage()
+      Column() {
+        Text(this.message)
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+### Referencing TS Classes and Methods in the HAR
+To reference the TS classes and methods exported from the HAR, use **import** as follows:
+```js
+// entry/src/main/ets/pages/index.ets
+import { Log } from "@ohos/library"
+import { func } from "@ohos/library"
+
+@Entry
+@Component
+struct Index {
+  build() {
+    Row() {
+      Column() {
+        Button('Button')
+          .onClick(()=>{
+            // Reference TS classes and methods in the HAR.
+            Log.info("har msg");
+            func();
+        })
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```
+### Referencing Resources in the HAR
+Use **$r** to reference resources in the HAR. For example, add the **name: hello_har** string (defined in the **string.json** file) and **icon_har.png** image to the **src/main/resources** directory of the HAR module, and then reference the string and image in the entry module. The code snippet is as follows:
+```js
+// entry/src/main/ets/pages/index.ets
+@Entry
+@Component
+struct Index {
+  build() {
+    Row() {
+      Column() {
+        // Reference the string in the HAR.
+        Text($r("app.string.hello_har"))
+          .fontSize(50)
+          .fontWeight(FontWeight.Bold)
+        // Reference the image in the HAR.
+        Image($r("app.media.icon_har"))
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```

+# In-Application HSP Development
+
+An in-application Harmony Shared Package (HSP) is a file used for code and resource sharing within an application (called the host application) and can only be invoked by a HAP or HSP of the same application.
+The in-application HSP is released with the Application Package (App Pack) of the host application and has the same bundle name and lifecycle as the host application.
+
+## Developing an In-Application HSP
+
+You can kickstart your HSP development with the HSP template in DevEco Studio. In this example, an HSP module named **library** is created. The basic project directory structure is as follows:
+```
+library
+├── src
+│   └── main
+│       ├── ets
+│       │   ├── pages
+│       │   └── index.ets
+│       ├── resources
+│       └── module.json5
+└── package.json
+```
+In the **module.json5** file, set **type** to **shared** for the HSP.
+```json
+{
+    "type": "shared"
+}
+```
+
+The HSP provides capabilities for external systems by exporting APIs in the entry file. Specify the entry file in **main** in the **package.json** file. For example:
+```json
+{
+    "main": "./src/main/ets/index.ets"
+}
+```
+
+### Exporting TS Classes and Methods
+Use **export** to export TS classes and methods. The sample code is as follows:
+```ts
+// library/src/main/ets/utils/test.ts
+export class Log {
+    static info(msg) {
+        console.info(msg);
+    }
+}
+
+export function add(a: number, b: number) {
+  return a + b;
+}
+
+export function minus(a: number, b: number) {
+  return a - b;
+}
+```
+In the entry file **index.ets**, declare the APIs to be exposed.
+```ts
+// library/src/main/ets/index.ets
+export { Log, add, minus } from './utils/test'
+```
+
+### Exporting ArkUI Components
+Use **export** to export ArkUI components. The sample code is as follows:
+```ts
+// library/src/main/ets/components/MyTitleBar.ets
+@Component
+export struct MyTitleBar {
+  build() {
+    Row() {
+      Text($r('app.string.library_title'))
+        .fontColor($r('app.color.white'))
+        .fontSize(25)
+        .margin({left:15})
+    }
+    .width('100%')
+    .height(50)
+    .padding({left:15})
+    .backgroundColor('#0D9FFB')
+  }
+}
+```
+In the entry file **index.ets**, declare the APIs to be exposed.
+```ts
+// library/src/main/ets/index.ets
+export { MyTitleBar } from './components/MyTitleBar'
+```
+#### About Using Resources in the HSP
+To reference resources in the **resources** directory of the current HSP module, use **$r** or **$rawfile**.
+If a relative path is used, the resources in the HSP caller are referenced instead. For example,
+if **Image("common/example.png")** is used in the HSP module, the **\<Image>** component will reference the resource **entry/src/main/ets/common/example.png** in the HSP caller (which is **entry** in this example).
+
+### Exporting Native Methods
+The HSP can contain .so files compiled in C++. The HSP indirectly exports the native method in the .so file. In this example, the **multi** method in the **libnative.so** file is exported.
+```ts
+// ibrary/src/main/ets/utils/nativeTest.ts
+import native from "libnative.so"
+
+export function nativeMulti(a: number, b: number) {
+    return native.multi(a, b);
+}
+```
+
+In the entry file **index.ets**, declare the APIs to be exposed.
+```ts
+// library/src/main/ets/index.ets
+export { nativeMulti } from './utils/nativeTest'
+```
+
+## Using the In-Application HSP
+To use APIs in the HSP, first configure the dependency on the HSP in the **package.json** file of the module that needs to call the APIs (called the invoking module). If the HSP and the invoking module are in the same project, the APIs can be referenced locally. The sample code is as follows:
+```json
+// entry/src/main/module.json5
+"dependencies": {
+    "library": "file:../library"
+}
+```
+You can now call the external APIs of the HSP in the same way as calling the APIs in the HAR.
+In this example, the external APIs are the following ones exported from **library**:
+```ts
+// library/src/main/ets/index.ets
+export { Log, add, minus } from './utils/test'
+export { MyTitleBar } from './components/MyTitleBar'
+export { nativeMulti } from './utils/nativeTest'
+```
+The APIs can be used as follows in the code of the invoking module:
+```ts
+// entry/src/main/ets/pages/index.ets
+import { Log, add, MyTitleBar, nativeMulti } from "library"
+
+@Entry
+@Component
+struct Index {
+  @State message: string = 'Hello World'
+  build() {
+    Row() {
+      Column() {
+        MyTitleBar()
+        Text(this.message)
+          .fontSize(30)
+          .fontWeight(FontWeight.Bold)
+        Button('add(1, 2)')
+          .onClick(()=>{
+            Log.info("add button click!");
+            this.message = "result: " + add(1, 2);
+          })
+        Button('nativeMulti(3, 4)')
+          .onClick(()=>{
+            Log.info("nativeMulti button click!");
+            this.message = "result: " + nativeMulti(3, 4);
+          })
+      }
+      .width('100%')
+    }
+    .height('100%')
+  }
+}
+```

+# Shared Package Overview
+
+OpenHarmony provides two types of shared packages: [Harmony Achive (HAR)](har-package.md) static shared package and Harmony Shared Package (HSP) dynamic shared package.
+
+Both the HAR and HSP are used to share code and resources and can contain code, C++ libraries, resources, and configuration files. The biggest differences between them are as follows: The code and resources in the HAR are compiled with the invoking module, and if there are multiple invoking modules, the build product contains multiple copies of the same code and resources; the code and resources in the HSP can be compiled independently, and the build product contains only one copy of the code and resources.
+
+**Figure 1** HAR and HSP in the App Pack
+
+![in-app-hsp-har](figures/in-app-hsp-har.png)
+
+The HSP is designed to solve the following issues with the HAR:
+- When multiple HAPs reference the same HAR, the size of the App Pack swells.
+- When multiple HAPs reference the same HAR, some state variables in the HAR cannot be shared.
+
+Restrictions on the HSP:
+- The HSP and its invoking modules must be in the stage model.
+- The HSP and its invoking modules must use the **esmodule **compilation mode.
+- The HSP does not support the declaration of **abilities** and **extensionAbilities** in its configuration file.
+
+The HSP can be classified as [in-application HSP](in-app-hsp.md) or [inter-application HSP](cross-app-hsp.md), depending on the configuration files and usage methods.

+# @ohos.file.fileUri (File URI)
+
+The **fileUri** module allows the uniform resource identifier (URI) of a file to be obtained based on the file path. With the file URI, you can use the APIs provided by [@ohos.file.fs](js-apis-file-fs.md) to operate the file.
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
+
+## Modules to Import
+
+```js
+import fileUri from "@ohos.file.fileUri";
+```
+
+Before using this module, you need to obtain the path of the file in the application sandbox. The following is an example:
+
+ ```js
+import UIAbility from '@ohos.app.ability.UIAbility';
+
+export default class EntryAbility extends UIAbility {
+    onWindowStageCreate(windowStage) {
+        let context = this.context;
+        let pathDir = context.filesDir;
+    }
+}
+ ```
+
+## fileUri.getUriFromPath
+
+getUriFromPath(path: string): string
+
+Obtains the URI of a file in synchronous mode.
+
+**System capability**: SystemCapability.FileManagement.AppFileService
+
+**Parameters**
+
+| Name| Type  | Mandatory| Description                      |
+| ------ | ------ | ---- | -------------------------- |
+| path   | string | Yes  | Path of the file in the application sandbox.|
+
+**Return value**
+
+| Type                          | Description        |
+| ---------------------------- | ---------- |
+| string | File URI obtained.|

+# @ohos.fileShare (File Sharing)
+
+The **fileShare** module provides APIs for granting the access permissions on a user file to another application by the Uniform Resource Identifier (URI). Then, the authorized application can access the file by using the APIs provided by [@ohos.file.fs](js-apis-file-fs.md).
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

HiTraceMeter APIs are provided in C++ and JS for event logging, which aims to generate the trace data necessary for performance tracing and analysis during the development process.
 
 The hitrace CLI tool is used to collect trace data. It captures trace data flows and saves the data as a text file.
 
 The smartperf tool allows you to perform data analysis manually or use the analysis script for automated data analysis. If you want to get the data analysis done automatically, you need to supply the data file generated by the hitrace CLI tool as the input for the smartperf tool.
 
-Traces data is classified by trace tag or trace category. Generally, one device subsystem corresponds to one tag. The tag is passed as the **Tag** parameter to event logging APIs. When you use the hitrace CLI tool to collect trace data, only the trace data specified by the **Tag** parameter is collected. Trace data of applications is fixedly labeled as **APP Tag**, and therefore, no **Tag** parameter needs to be passed to JS APIs. The following is a list of trace tags supported by HiTraceMeter. You can view the tags in [hitrace_meter.h](https://gitee.com/openharmony/hiviewdfx_hitrace/blob/master/interfaces/native/innerkits/include/hitrace_meter/hitrace_meter.h).

+## Implementation Principles
 
 HiTraceMeter provides the hitrace CLI tool for capturing trace data in user mode and kernel mode, and provides C++ (innerkits) and JS (kits) APIs for event logging in user mode. Through extending kernel's ftrace functionality, HiTraceMeter can use the trace_marker node of ftrace to write the data, which is written into the user space by event logging APIs, to the kernel buffer. The following figure shows the basic HiTraceMeter architecture.

 ## Constraints
 
 - The implementation of HiTraceMeter functions and APIs depends on the ftrace functionality, a framework provided by the kernel. It enables developers to add more trace functions via plug-ins. Therefore, make sure that ftrace is enabled before you use HiTraceMeter.
- For most Linux kernels, ftrace is enabled by default. For details, see the ftrace documentation you may obtain.

 ## How to Develop
+
 1. Add the build dependencies to the build configuration file **base\hiviewdfx\hitrace\cmd\BUILD.gn**.
+   
+   ```
+   external_deps = [ "hitrace_native:hitrace_meter"]
+   ```
 
-    ```
-    external_deps = [ "hitrace_native:hitrace_meter"]
-    ```
 2. Add the header file dependencies.
-
-    ```cpp
-    #include "hitrace_meter.h"// Header file for defining APIs
-    ```
-
-3. When calling an API, pass the trace value as an input parameter. After the hitrace command is executed in the shell, the trace data is automatically captured. The captured data includes the function call process and the memory and time consumed during this process. You can use the data to analyze the call process to identify performance problems.
-
-
-    ```cpp
-    
-     CountTrace(label, "count number", 2000);  // Integer trace
-         
-     StartTrace(label, "func1Trace", -1); // Trace start point of func1Start
-         
-     FinishTrace(label);   // Trace end point of func1Trace
-         
-     StartAsyncTrace(label, "asyncTrace1", 1234); // Start point of asyncTrace1
-    
-     FinishAsyncTrace(label, "asyncTrace2", 3456); // End point of asyncTrace2
-    ```
+   
+   ```cpp
+   #include "hitrace_meter.h"// Header file for defining APIs
+   ```
+
+3. When calling an API, pass the trace value as an input parameter. The trace tags currently supported are listed in **hitrace_meter.h**. Assume that the trace tag is **OHOS** and trace data of **func1** and **func2** needs to be captured. After the hitrace command is executed in the shell, the trace data is automatically captured. The captured data includes the function call process and the memory and time consumed during this process. You can use the data to analyze the call process to identify performance problems.
+   
+   ```cpp
+   #include "hitrace_meter.h" // Include hitrace_meter.h
+   using namespace std;
+   
+   int main()
+   {
+      uint64_t label = BYTRACE_TAG_OHOS;
+      sleep(1);
+      CountTrace(label, "count number", 2000);  // Integer trace
+   
+      StartTrace(label, "func1Trace", -1); // Trace start point of func1Start
+      sleep(1);
+      StartTrace(label, "func2Trace", -1);   // Trace start point of func2Start
+      sleep(2);
+      FinishTrace (label); // Trace end point of func2Trace
+      sleep(1);
+      FinishTrace(label);   // Trace end point of func1Trace
+   
+      StartAsyncTrace(label, "asyncTrace1", 1234); // Trace start point of asyncTrace1  
+      FinishAsyncTrace(label, "asyncTrace1", 1234); // Trace end point of asyncTrace1
+   
+      return 0;
+   } 
+   ```
 
 4. On completion of HiTraceMeter building and deployment, start a trace. After you run the application in the shell on the device, trace data will be captured automatically.
-
-    ```
-    hdc_std shell hitrace -t 10 ohos > .\myapp_demo.ftrace
-    ```
-
- You can open the captured data by clicking **Open trace file** in the smartperf tool or dragging the data to the graphics area. For details, see [smartperf](https://toscode.gitee.com/openharmony-sig/smartperf).
-
-## Development Example
-
-You can access a full list of trace tags supported by HiTraceMeter in **hitrace_meter.h**. The following uses the **OHOS** tag as an example to illustrate how to obtain the trace data of the **func1** and **func2** functions.

-     StartTrace(label, "func1Trace", -1); // Trace start point of func1Start
-     sleep(1);
-     StartTrace(label, "func2Trace", -1);   // Trace start point of func2Start
-     sleep(2);
-     FinishTrace (label); // Trace end point of func2Trace
-     sleep(1);
-     FinishTrace(label);   // Trace end point of func1Trace
- 
-     return 0;
- }   
-```

-        StartTrace(LABEL, "funcAStart", SLEEP_ONE_SECOND); // Trace start point
-        FuncA();
-        FinishTrace(LABEL);
-        sleep(SLEEP_TWO_SECOND);
-    
-        thread t2(ThreadFunc2);
-        t2.join();
-    
-        StartTrace(LABEL, "funcBStart", SLEEP_TWO_SECOND);
-        FuncB();
-        FinishTrace(LABEL);// Trace end point
-        sleep(SLEEP_TWO_SECOND);
-    
-        sleep(SLEEP_ONE_SECOND);
-        FinishTrace(LABEL);
-        FuncC();
-    
-        return 0;
-    }
-    ```
+   
+   ```cpp

+   {
+       thread t1(ThreadFunc1);
+       t1.join();

+       sleep(SLEEP_ONE_SECOND);
+   
+       StartTrace(LABEL, "funcAStart", SLEEP_ONE_SECOND); // Trace start point
+       FuncA();
+       FinishTrace(LABEL);
+       sleep(SLEEP_TWO_SECOND);
+   
+       thread t2(ThreadFunc2);
+       t2.join();
+   
+       StartTrace(LABEL, "funcBStart", SLEEP_TWO_SECOND);
+       FuncB();

+       FinishTrace(LABEL);
+       FuncC();
+   
+       return 0;
+   }
+   ```
 
 2. Modify the **base\hiviewdfx\hitrace\cmd\BUILD.gn** file, and start building.
-
-    ```
-    ohos_executable("hitrace_example") {
-      sources = [ "example/hitrace_example.cpp" ]

-      subsystem_name = "hiviewdfx"
-      part_name = "hitrace_native"
-    }
-    
-    group("hitrace_target") {
-      deps = [
-        ":hitrace",
-        ":hitrace_example",
-      ]
-    }
-    ```
+   
+   ```
+   ohos_executable("hitrace_example") {
+     sources = [ "example/hitrace_example.cpp" ]
+   
+     external_deps = [ "hitrace_native:hitrace_meter" ]
+   
+     subsystem_name = "hiviewdfx"
+     part_name = "hitrace_native"
+   }
+   
+   group("hitrace_target") {
+     deps = [
+       ":hitrace",
+       ":hitrace_example",
+     ]
+   }
+   ```
 
 3. Place the **hitrace_example** executable file in the **/system/bin** directory of the device, and run the following commands in sequence in the shell:
-
-    ```shell
-    hitrace --trace_begin ohos
-    hitrace_exampe
-    hitrace --trace_dump
-    ```
-
+   
+   ```shell
+   hitrace --trace_begin ohos
+   hitrace_exampe
+   hitrace --trace_dump
+   ```
+   
     If the expected trace value is present in the trace data, the capture of trace data is successful. For example:

+# System Brightness Customization
+
+## Overview
+
+### Introduction
+
+By default, the system brightness of OpenHarmony ranges from **0** to **255** (**0** indicates the minimum luminance and **255** the maximum). It is applicable to the entire system and all application windows. Due to hardware restrictions, some display devices are unable to support the system brightness range. To address this issue, OpenHarmony provides the function of customizing the system brightness range. This way, you can adjust the system brightness range based on the hardware specifications of the display devices.
+
+### Basic Concepts
+
+**System brightness**
+Global brightness of OpenHarmony. The customized brightness range is effective for all application windows.
+
+**Window brightness**
+Brightness of an application window. The customized brightness range is effective only for this application window. After a brightness is specified for an application window, its brightness is not affected by the system brightness.
+
+### Constraints
+
+The [sysparam](./subsys-boot-init-sysparam.md) module of OpenHarmony provides an easy-to-use key-value pair access interface for system services to configure service functions based on their own system parameters. The customization of the system brightness range is dependent on this feature.
+
+## How to Develop
+
+### Setting Up the Environment
+
+**Hardware requirements:**
+
+Development board running the standard system, for example, the DAYU200 or Hi3516D V300 open source suite.
+
+**Environment requirements:**
+
+For details about the requirements on the Linux environment, see [Quick Start](../quick-start/Readme-EN.md).
+
+### How to Develop
+
+1. In the target directory, create a target folder by referring to the [default brightness value configuration folder](https://gitee.com/openharmony/powermgr_display_manager/tree/master/service/etc). The file format is as follows:
+     
+    ```text
+    etc
+    ├── BUILD.gn
+    ├── display.para
+    ├── display.para.dac
+    ```
+
+2. Write the customized **display.para** file by referring to the [**display.para** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/display.para) in the default brightness range configuration folder. Include the customized brightness thresholds, for example, **max=150**, **default=75**, and **min=50**, into the file:
+
+    ```shell
+    # Brightness limits is 0-255.
+    const.display.brightness.min=50
+    const.display.brightness.default=75
+    const.display.brightness.max=150
+    ``` 
+
+3. Write the customized **display.para.dac** file by referring to the [**display.para.dac** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/display.para.dac) in the default brightness range configuration folder, so as to grant the permission required to access the customized configuration.
+
+    ```shell
+    const.display.brightness.="foundation:foundation:444"
+    ``` 
+
+4. Write the customized **BUILD.gn** file by referring to the [**BUILD.gn** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/service/etc/BUILD.gn) in the default brightness range configuration folder. Then, put the **display.para** and **display.para.dac** files to the **/vendor/etc/param** directory. For example:
+
+    ```shell
+    import("//base/powermgr/display_manager/displaymgr.gni")
+    import("//build/ohos.gni")
+
+    ## Install display.para to /vendor/etc/param/display.para
+    ohos_prebuilt_etc("display.para") {
+    source = "display.para"
+    relative_install_dir = "param"
+    install_images = [ chipset_base_dir ]
+    part_name = "${displaymgr_part_name}"
+    subsystem_name = "powermgr"
+    }
+
+    ohos_prebuilt_etc("display.para.dac") {
+    source = "display.para.dac"
+    relative_install_dir = "param"
+    install_images = [ chipset_base_dir ]
+    part_name = "${displaymgr_part_name}"
+    subsystem_name = "powermgr"
+    }
+
+    group("param_files") {
+    deps = [
+        ":display.para",
+        ":display.para.dac",
+    ]
+    }
+    ```
+
+5. Write the customized **bundle.json** file by referring to the [**bundle.json** file](https://gitee.com/openharmony/powermgr_display_manager/blob/master/bundle.json) in the default brightness range configuration folder, so as to compile the **BUILD.gn** file.
+ 
+    ```shell
+    "service_group": [ "//base/powermgr/display_manager/service/etc:param_files" ]
+    ``` 
+    In the preceding code, **//base/powermgr/display_manager/service** indicates the directory of the created folder, and **etc** indicates the folder name.
+
+6. Build the customized version by referring to [Quick Start](../quick-start/Readme-EN.md). The following command uses DAYU200 as an example:
+
+    ```shell
+    ./build.sh --product-name rk3568 --ccache
+    ```
+
+7. Burn the customized version to the DAYU200 development board.
+
+### Debugging and Verification
+
+1. After startup, run the following command to launch the shell command line:
+
+    ```shell
+    hdc shell
+    ```
+
+2. Run the following command to check the console output:
+
+    ```shell
+    hidumper -s 3308 -a -a
+    ```
+
+3. Check the console output for the customized system brightness thresholds.
+
+    The default system brightness thresholds are as follows:
+
+    ```shell
+    ----------------------------------DisplayPowerManagerService---------------------------------
+    DISPLAY POWER MANAGER DUMP:
+    Display Id=0 State=2 Discount=1.000000 Brightness=102
+    DeviceBrightness=102
+    Support Ambient Light: FALSE
+    Auto Adjust Brightness: OFF
+    Brightness Limits: Max=255 Min=5 Default=102
+
+    ```
+
+    Assume that the system brightness thresholds are set to **Max=150 Min=50 Default=75**. The console output is as follows:
+
+    ```shell
+    # cd vendor/etc/param                                                          
+    # ls
+    display.para      thermal.para      usb.para.dac  
+    display.para.dac  thermal.para.dac

+## cl.resourceManager.1 Change in the Meaning of the Return Value for the API Used to Obtain the rawfile Descriptor
+
+Changed the meaning of the return value for the API used to obtain the rawfile descriptor after the non-decompression feature is added in this version. The change in the meaning of the return value, namely, **descriptor: RawFileDescriptor {fd, offset, length}**, is described as follows:
+
+**Before change:**
+
+**fd**: file descriptor for accessing the rawfile.
+
+**offset**: offset for accessing the rawfile. In this case, the value is **0**.
+
+**length**: size of the rawfile to access.
+
+**After change:**
+
+**fd**: file descriptor for accessing the HAP where the rawfile is located.
+
+**offset**: offset of the accessed rawfile relative to the HAP.
+
+**length**: size of the rawfile to access.
+
+**Change Impact**
+
+In versions earlier than 4.0.2.2, the rawfile can be accessed only through **fd**. In version 4.0.2.2 or later, the rawfile can be accessed only through **{fd, offset, and length}**.
+
+**Key API/Component Changes**
+
+| **Original API**                           | 
+| ----------------                         | 
+| getRawFd(path: string, callback: AsyncCallback\<RawFileDescriptor>): void   | 
+| getRawFd(path: string): Promise\<RawFileDescriptor>  |
+| getRawFileDescriptor(path: string, callback: AsyncCallback\<RawFileDescriptor>): void|
+| getRawFileDescriptor(path: string): Promise\<RawFileDescriptor>|
+||
+
+**Sample Code**
+
+The following is an example of calling the **getRawFd** API:
+```
+try {
+    this.context.resourceManager.getRawFd("test.ogg", (error, value) => {
+        if (error != null) {
+            console.log(`callback getRawFd failed error code: ${error.code}, message: ${error.message}.`);
+        } else {
+            let fileDescriptor = {
+                fd = value.fd,
+                offset = value.offset,
+                length = value.length
+            }
+            this.avPlayer.fdSrc(fileDescriptor); // Take the audio player as an example. When calling fdSrc, pass fileDescriptor in addition to fd.
+        }

+3. 调用该对象的on()方法，可以根据业务需要订阅HTTP响应头事件、HTTP流式响应数据接收事件、HTTP流式响应数据接收进度事件和HTTP流式响应数据接收完毕事件。
+4. 调用该对象的request2()方法，传入http请求的url地址和可选参数，发起网络请求。

+# Native API
+Native API是OHOS SDK上提供的一组native开发接口与工具集合，方便开发者使用C或者C++语言实现应用的关键功能。Native API只覆盖了OHOS基础的一些底层能力，如libc，图形库，窗口系统，多媒体，压缩库等，并没有完全提供类似于JS API上的完整的OHOS 平台能力。在应用中使用Native API会编译成动态库打包到应用中。
+
+<br/>
+
+## Native API构成介绍
+
+### Native API目录结构
+
+Native API在SDK包的位置为$(SDK_ROOT)/native目录，主要有以下几个部分组成
+
+|目录|功能说明|
+|--|--|
+|build|应用中编译动态库的toolchain cmake脚本；这个目录下ohos.toolchain.cmake文件定义了给OHOS交叉编译选项|
+|build-tools|放置编译构建的工具，如cmake|
+|docs|Native API接口参考文档，通过doxgen从头文件中提取出来|
+|llvm|支持OHOS ABI的llvm交叉编译器|
+|sysroot|放置编译链接的依赖文件目录，包含头文件，动态库等|
+
+<br/>
+
+### Native API接口
+
+|接口分类|接口功能|引入版本|
+|--|--|--|
+|标准C库|以musl为基础提供的标准c库接口，当前提供了1500+的接口|8|
+|标准C++库|c++运行时库libc++_shared，此库在打包的时候需要打包或者静态链接到应用中|8|
+|日志|打印日志到系统的hilog接口|8|
+|napi|ArkUI提供的，方便应用开发接入JS应用环境的一组类Node-API，是属于Native API的一部分|8|
+|XComponent|ArkUI XComponent组件中的surface与触屏事件接口，方便开发者开发高性能图形应用|8|
+|libuv|ArkUI集成的三方的异步IO库|8|
+|libz|zlib库，提供基本的压缩，解压接口|8|
+|Drawing|系统提供的2D图形库，可以在surface进行绘制|8|
+|OpenGL|系统提供的openglv3接口|8|
+|Rawfile|应用资源访问接口，可以读取应用中打包的各种资源|8|
+|OpenSLES|用于2D，3D音频加速的接口库|8|
+|Mindspore|AI模型接口库|9|
+|包管理|包服务接口，方便查询应用包信息|8|
+
+Native API中有一部分接口采用开源标准，详细列表见《[Native API中支持的标准库](https://docs.openharmony.cn/pages/v3.1/zh-cn/application-dev/reference/native-lib/third_party_libc/musl.md/)》《[Node_API](https://docs.openharmony.cn/pages/v3.1/zh-cn/application-dev/reference/native-lib/third_party_napi/napi.md/)》
+
+## 使用介绍
+
+<br/>
+
+### 建议使用Native API的场景
+
+主要有如下一些
+
+1. 应用性能敏感代码，比如游戏，物理模拟等计算密集型场景
+2. 需要复用已有的C或C++库
+3. 需要针对CPU特性进行专项定制的库，如neon加速
+
+<br/>
+
+### 不建议使用Native API的场景
+
+1. 写一个纯native的的OHOS应用
+2. 希望在尽可能多的OHOS设备上保持兼容的应用
+
+<br/>

+# 媒体查询
+
+>  **说明：**
+>
+>  - 从API version 8 开始支持。后续版本如有新增内容，则采用上角标单独标记该内容的起始版本。
+>
+>  - media属性值默认为设备的真实尺寸大小、物理像素和真实的屏幕分辨率。
+
+
+媒体查询（Media Query）应用十分广泛，开发者经常需要根据设备的大致类型或者特定的特征和设备参数（例如屏幕分辨率）来修改应用的样式。使用媒体查询针对设备和应用的属性信息，可以设计出相匹配的布局样式。
+
+
+## CSS语法规则
+
+使用@media来引入查询语句，具体规则如下：
+
+```
+@media [media-type] [and|or] [(media-feature)] {
+  CSS-Code;
+}
+```
+
+@media screen and (round-screen: true) { … } ： 当设备屏幕是圆形时条件成立
+
+@media (max-height: 454) { … } ：范围查询，CSS level 3 写法
+
+>  **说明：**
+>
+>  - 不支持&lt;=，&gt;=，&lt;，&gt;操作符;
+>  - api 9开始才支持多重 () 嵌套使用；
+>  - media语句整体长度不能超过 512 个字符；
+>  - 单个media条件长度不能超过32个字符；
+
+
+## 媒体类型
+
+| 类型     | 说明             |
+| ------ | -------------- |
+| screen | 按屏幕相关参数进行媒体查询。 |
+
+
+## 媒体逻辑操作
+
+媒体逻辑操作符：and、or<sup>9+</sup>用于构成媒体查询语句，详细解释说明如下表。
+
+**表1** 媒体逻辑操作符
+
+| 类型            | 说明                                                         |
+| --------------- | ------------------------------------------------------------ |
+| and             | 将多个媒体特征（Media&nbsp;Feature）以“与”的方式连接成一个媒体查询，只有当所有媒体特征都为true，查询条件成立。另外，它还可以将媒体类型和媒体功能结合起来。<br/>例如：screen&nbsp;and&nbsp;(device-type:&nbsp;liteWearable)&nbsp;and&nbsp;(max-height:&nbsp;454)&nbsp;表示当设备类型是智能穿戴同时应用的最大高度小于等于454个像素单位时成立。 |
+| or<sup>9+</sup> | 将多个媒体特征以“或”的方式连接成一个媒体查询，如果存在结果为true的媒体特征，则查询条件成立。<br/>例如：screen&nbsp;and&nbsp;(max-height:&nbsp;454) &nbsp;or&nbsp;&nbsp;（round-screen：true）表示当应用高度小于等于454个像素单位或者设备屏幕是圆形时，条件成立。 |
+
+
+
+
+## 媒体特征
+
+| 类型             | 说明                                                         |
+| ---------------- | ------------------------------------------------------------ |
+| height           | 应用页面显示区域的高度。                                     |
+| min-height       | 应用页面显示区域的最小高度。                                 |
+| max-height       | 应用页面显示区域的最大高度。                                 |
+| width            | 应用页面显示区域的宽度。                                     |
+| min-width        | 应用页面显示区域的最小宽度。                                 |
+| max-width        | 应用页面显示区域的最大宽度。                                 |
+| aspect-ratio     | 应用页面显示区域的宽度与高度的比值。<br/>例如：aspect-ratio: 1/2 |
+| min-aspect-ratio | 应用页面显示区域的宽度与高度的最小比值。                     |
+| max-aspect-ratio | 应用页面显示区域的宽度与高度的最大比值。                     |
+| round-screen     | 屏幕类型，圆形屏幕为 true，&nbsp;非圆形屏幕为&nbsp;false。   |
+
+
+## 通用媒体特征示例代码

 ## 开发实例
 
 
-### C++接口开发实例

-### 线程卡死监控
+### 线程卡死监控开发实例
 
 线程卡死监控功能需要开发者实现两个卡死检测回调函数，XCollieChecker类的CheckBlock和CheckThreadBlock接口函数。实现了该回调函数之后，开发者还需要通过XCollie类的RegisterXCollieChecker函数，将该回调函数的类实例成功注册。卡死监控线程会定时执行全部已成功注册的回调函数，检查线程逻辑完成标志位，判定已经成功注册的线程逻辑是否被卡死。
