 # Subscribing to State Changes of a Remote Object
 
+## Overview
+
 IPC/RPC allows you to subscribe to the state changes of a remote stub object. When the remote stub object dies, a death notification will be sent to your local proxy object. Such subscription and unsubscription are controlled by APIs. To be specific, you need to implement the **DeathRecipient** interface and the **onRemoteDied** API to clear resources. This callback is invoked when the process accommodating the remote stub object dies, or the device accommodating the remote stub object leaves the network. It is worth noting that these APIs should be called in the following order: The proxy object must first subscribe to death notifications of the stub object. If the stub object is in the normal state, the proxy object can cancel the subscription as required. If the process of the stub object exits or the device hosting the stub object goes offline, subsequent operations customized by the proxy object will be automatically triggered.
 
 ## When to Use

en/application-dev/connectivity/websocket-connection.md

 # WebSocket Connection
 
-## When to Use
+## Overview
 
 You can use WebSocket to establish a bidirectional connection between a server and a client. Before doing this, you need to use the **createWebSocket()** API to create a **WebSocket** object and then use the **connect()** API to connect to the server. If the connection is successful, the client will receive a callback of the **open** event. Then, the client can communicate with the server using the **send()** API. When the server sends a message to the client, the client will receive a callback of the **message** event. If the client no longer needs this connection, it can call the **close()** API to disconnect from the server. Then, the client will receive a callback of the **close** event.

 # Development of Error Manager
 
-## When to Use
+## Overview
 
 If coding specification issues or errors exist in the code of an application, the application may encounter unexpected errors, for example, uncaught exceptions or application lifecycle timeouts, while it is running. In such a case, the application may exit unexpectedly. Error logs, however, are usually stored on users' local storage, making it inconvenient to locate faults. With the APIs provided by the **errorManager** module, your application will be able to report related errors and logs to your service platform for fault locating before it exits.

 A traditional log system aggregates log information generated by all applications running on the entire device, making it difficult to identify key information in the log. Therefore, an effective logging mechanism is needed to evaluate mission-critical information, for example, number of visits, number of daily active users, user operation habits, and key factors that affect application usage.

 ## Overview
 
 
-### Introduction
+### Function Introduction
 
-HiSysEvent supports listening for events across processes. You can register a listener to listen for concerned events on a real-time basis. For example, you can enable the battery module to listen for power consumption events for power usage analysis.
+HiSysEvent supports listening for events across processes. You can register a listener to listen for concerned events on a real-time basis. For example, you can enable the battery module to subscribe to power consumption events for power usage analysis.
 
 
 ### Constraints
 
-Before subscribing to system events, you need to configure HiSysEvent logging. For details, see [HiSysEvent Logging Configuration](../subsystems/subsys-dfx-hisysevent-logging-config.md).

-## How to Develop
-
-
-### **C++**
-
-The following provides an example of how to use C++ APIs of **HiSysEvent**.
-
-1. Develop the source code.
-   Import the **DemoListener.h** header file, which contains the **DemoListener** class for implementing the custom event callback.
-
-   ```
-   #ifndef DEMO_LISTENER_H
-   #define DEMO_LISTENER_H
-
-   #include "hisysevent_listener.h"
-
-   #include <string>
-
-   class DemoListener : public OHOS::HiviewDFX::HiSysEventListener {
-   public:
-       explicit DemoListener() : HiSysEventListener() {}
-     virtual ~DemoListener() {}
-
-   public:
-       void OnEvent(std::shared_ptr<HiSysEventRecord> sysEvent);
-       void OnServiceDied();
-   };
-   
-   #endif // DEMO_LISTENER_H
-   ```
-
-   Create the **DemoListener.cpp** file, and add the implementation logic of the custom event callback API in the **DemoListener** class.
-
-   ```
-   #include "demo_listener.h"
-
-   #include <iostream>
-
-   void DemoListener::OnEvent(std::shared_ptr<HiSysEventRecord> sysEvent)
-   {
-       if (sysEvent == nullptr) {
-           return;

+
+### How to Develop
+
+#### C++ HiSysEvent Listening
+
+1. Import the corresponding header file.
+
+    ```c++
+    #include "hisysevent_manager.h"
+    ```
+
+2. Implement the callback API for the service domain.
+
+    ```c++
+    class TestListener : public OHOS::HiviewDFX::HiSysEventListener {
+    public:
+        void OnEvent(std::shared_ptr<HiSysEventRecord> record)
+        {
+            if (record == nullptr) {
+                return;
+            }
+            std::cout << record->AsJson() << std::endl;
+        }
+
+        void OnServiceDied()
+        {
+            std::cout << std::string("service disconnect, exit") << std::endl;
+            exit(0);
+        }
+    };
+    ```
+
+3. Call the listening API while passing in parameters such as **listener** and **rules**. When the service ends, disable event listening.
+
+    ```c++
+    auto testListener = std::make_shared<TestListener>();
+    // Add a ListenerRule object based on the event tag, with RuleType left unspecified (in this case, ruleType is defaulted to WHOLE_WORD).
+    ListenerRule tagRule("dfx");
+    // Add a ListenerRule object based on the event tag, with RuleType set as REGULAR.
+    ListenerRule regRule("dfx.*", RuleType::REGULAR);
+    // Add a ListenerRule object based on the event domain and event name, with RuleType set as PREFIX.
+    ListenerRule domainNameRule("HIVIEWDFX", "APP_USAGE", RuleType::PREFIX);
+    std::vector<ListenerRule> sysRules;
+    sysRules.push_back(tagRule);
+    sysRules.push_back(regRule);
+    sysRules.push_back(domainNameRule);
+    // Start event listening.
+    auto ret = HiSysEventManager::AddEventListener(testListener, sysRules);
+    // Remove the listener when the service ends.
+    if (ret == 0) {
+       HiSysEventManager::RemoveListener(testListener);
+    }
+    ```
+
+#### C HiSysEvent Listening
+
+1. Import the corresponding header file.
+
+    ```c++
+    #include "hisysevent_manager_c.h"
+    ```
+
+2. Implement the callback API for the service domain.
+
+    ```c++
+    void OnEventTest(HiSysEventRecord record)
+    {
+        printf("OnEventTest: event=%s", record.jsonStr);
+    }
+
+    void OnServiceDiedTest()
+    {
+        printf("OnServiceDied");
+    }
+    ```
+
+3. Call the listening API while passing in parameters such as **watcher** and **rules**. When the service ends, disable event listening.
+
+    ```c++
+    HiSysEventWatcher watcher;
+    watcher.OnEvent = OnEventTest;
+    watcher.OnServiceDied = OnServiceDiedTest;
+    // Add a HiSysEventWatchRule object based on the event tag, with RuleType left unspecified (in this case, ruleType is defaulted to WHOLE_WORD).
+    constexpr char DFX_TAG[] = "dfx";
+    HiSysEventWatchRule tagRule;
+    (void)strcpy_s(tagRule.tag, strlen(DFX_TAG) + 1, DFX_TAG);
+    tagRule.ruleType = 1;
+    tagRule.eventType = 0;
+    // Add a HiSysEventWatchRule object based on the event tag, with RuleType set as REGULAR.
+    constexpr char DFX_PATTERN_TAG[] = "dfx.*";
+    HiSysEventWatchRule regRule;
+    (void)strcpy_s(regRule.tag, strlen(DFX_PATTERN_TAG) + 1, DFX_PATTERN_TAG);
+    regRule.ruleType = 3;
+    regRule.eventType = 0;
+    // Add a HiSysEventWatchRule object based on the event domain and event name, with RuleType set as PREFIX.
+    constexpr char DOMAIN[] = "HIVIEWDFX";
+    constexpr char NAME[] = "APP_USAGE";
+    HiSysEventWatchRule domainNameRule;
+    (void)strcpy_s(domainNameRule.domain, strlen(DOMAIN) + 1, DOMAIN);
+    (void)strcpy_s(domainNameRule.name, strlen(NAME) + 1, NAME);
+    domainNameRule.ruleType = 2;
+    domainNameRule.eventType = 0;
+    // Start event listening.
+    HiSysEventWatchRule rules[] = {tagRule, regRule, domainNameRule};
+    int ret = OH_HiSysEvent_Add_Watcher(&watcher, rules, sizeof(rules) / sizeof(HiSysEventWatchRule));
+    // Remove the watcher when the service ends.
+    if (ret == 0) {
+        ret = OH_HiSysEvent_Remove_Watcher(&watcher);
+    }
+    ```
+
+### Development Examples
+
+#### C++ HiSysEvent Listening
+
+Suppose you want to enable listening for all events whose domain is **HIVIEWDFX** and name is **PLUGIN_LOAD**. The sample code is as follows:
+
+1. Add the **libhisysevent** and **libhisyseventmanager** dependencies of the **hisysevent** component to the **BUILD.gn** file of the service module.
+
+    ```c++
+    external_deps = [
+      "hisysevent:libhisysevent",
+      "hisysevent:libhisyseventmanager",
+    ]
+    ```
+
+2. Call the listening API in the **TestEventListening()** function. When the service ends, disable event listening.
+
+    ```c++
+    #include <iostream>
+
+    #include "hisysevent_manager.h"
+
+    using namespace OHOS::HiviewDFX;
+
+    class TestListener : public HiSysEventQueryCallback {

+        {
+            if (record == nullptr) {
+                return;
+            }
+            std::cout << record->AsJson() << std::endl;

+## request2 API Name Change
+
+Changed the name of the HTTP streaming request from **request2** to **requestInStream**. The original name **request2** does not clearly express the intent of the API and may cause ambiguity, which does not comply with the OpenHarmony API specifications. 
+ 
+  -  
+
+## dataProgress Event Name Change
+
+Changed the name of the streaming data receiving event from **dataProgress** to **dataReceiveProgress**. The original name **dataProgress** does not clearly express the meaning of the event, which does not comply with the OpenHarmony API specifications. 
+ 
+  -  
+
+**Change Impact**
+
+For applications developed based on earlier versions, the corresponding API and event names must be updated. Otherwise, API calls may fail, affecting the service logic.
+
+**Key API/Component Changes**
+
+Involved APIs:
+
+  - request2;
+  - on(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+  - off(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+
+Before change:
+  - request2(url: string, callback: AsyncCallback<number>): void;
+  - request2(url: string, options: HttpRequestOptions, callback: AsyncCallback<number>): void;
+  - request2(url: string, options?: HttpRequestOptions): Promise<number>;
+  - on(type: "dataProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+  - off(type: 'dataProgress', callback?: Callback<{ receiveSize: number, totalSize: number }>): void;
+
+After change:
+  - requestInStream(url: string, callback: AsyncCallback<number>): void;
+  - requestInStream(url: string, options: HttpRequestOptions, callback: AsyncCallback<number>): void;
+  - requestInStream(url: string, options?: HttpRequestOptions): Promise<number>;
+  - on(type: "dataReceiveProgress", callback: Callback<{ receiveSize: number, totalSize: number }>): void;
+  - off(type: 'dataReceiveProgress', callback?: Callback<{ receiveSize: number, totalSize: number }>): void;
+
+**Adaptation Guide**
+
+Replace the API name **request2** and event name **dataProgress** in the original service code with **requestInStream** and **dataReceiveProgress**, respectively.

+## cl.hiviewdfx.1 Event Verification Specification Change for the write Method of the HiAppEvent Module
+
+Extended the event verification specifications for the **write** method of the HiAppEvent module to support predefined events of HUAWEI Analytics. Specific changes are as follows:
+
+  - The event name can start with a dollar sign ($) and can contain uppercase letters, lowercase letters, digits, and underscores (_). Before the change, the event name can contain lowercase letters, digits, and underscores (_).
+  - The event parameter name can start with a dollar sign ($) and can contain uppercase letters, lowercase letters, digits, and underscores (_). Before the change, the event parameter name can contain lowercase letters, digits, and underscores (_).
+
+**Change Impact**
+
+More event definition formats are supported for event logging.
+
+**Key API/Component Changes**
+
+Involved APIs:
+
+  - hiAppEvent.write;
+
+**Adaptation Guide**
+
+The event verification specifications are downward compatible. No additional adaptation is required.

+## cl.telephony.1 VoNRState Enum Value Change of setVoNState
+
+Changed the **VoNRState** enum values of the **setVoNState** API. The values value of **VONR_STATE_ON** is changed from **0** to **1** and that of **VONR_STATE_OFF** is defined as **0** to keep consistency with boolean values.
+
+**Change Impact**
+
+The new **VoNRState** enum values need to be used when **setVoNState** is called. The API function remains unchanged.
+
+**Key API/Component Changes**
+
+Before change:
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<void>): void;
+
+/**
+ * @systemapi Hide this for inner system use.
+ * @since 10
+ */
+export enum VoNRState {
+    /** Indicates the VoNR switch is on */
+    VONR_STATE_ON = 0,
+}
+```
+
+After change:
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<void>): void;
+
+/**
+ * Indicates the VoNR state.
+ *
+ * @enum { number }
+ * @syscap SystemCapability.Telephony.CallManager
+ * @systemapi Hide this for inner system use.
+ * @since 10
+ */
+export enum VoNRState {
+    /**
+     * Indicates the VoNR switch is off.
+     *
+     * @syscap SystemCapability.Telephony.CallManager
+     * @systemapi Hide this for inner system use.
+     * @since 10
+     */
+    VONR_STATE_OFF = 0,
+
+    /**
+     * Indicates the VoNR switch is on.
+     *
+     * @syscap SystemCapability.Telephony.CallManager
+     * @systemapi Hide this for inner system use.
+     * @since 10
+     */
+    VONR_STATE_ON = 1,
+}
+```
+
+
+**Adaptation Guide**
+
+When calling **setVoNState**, use the new **VoNRState** enum values. The sample code is as follows:
+
+
+```js
+call.setVoNRState( 0, VONR_STATE_ON, (err) => {
+    if (err) {
+        console.log(`callback: err->${JSON.stringify(err)}`);
+    }
+    
+});
+call.setVoNRState( 0, VONR_STATE_OFF, (err) => {
+    console.log(`callback: err->${JSON.stringify(err)}`);
+});
+```
+
+
+## cl.telephony.2 Callback Value Change of setVoNState
+
+Changed the callback value of **setVoNState** from a boolean value to **void**.
+
+**Change Impact**
+
+The callback value needs to be set to **void** when **setVoNState** is called.
+
+**Key API/Component Changes**
+
+Before change:
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<boolean>): void;
+function setVoNRState(slotId: number, state: VoNRState): Promise<boolean>;
+
+```
+
+After change:
+
+```js
+function setVoNRState(slotId: number, state: VoNRState, callback: AsyncCallback<void>): void;
+function setVoNRState(slotId: number, state: VoNRState): Promise<void>;
+```
+
+**Adaptation Guide**
+
+Set the callback value to **void** when calling **setVoNState**. The sample code is as follows:
+
+```js
+call.setVoNRState( 0, VONR_STATE_ON, (err) => {
+    if (err) {
+        console.log(`callback: err->${JSON.stringify(err)}`);
+    }
+    
+});
+call.setVoNRState( 0, VONR_STATE_OFF, (err) => {
+    console.log(`callback: err->${JSON.stringify(err)}`);
+});
+```
