-## How to Develop
-
-   The following describes how to obtain the raw file list, raw file content, and raw file descriptor on the JavaScript side as an example.
-
-1. Create a project.
-
-![Creating a C++ application](figures/rawfile1.png)
-
-2. Add dependencies.
-
-After a project is created, the **cpp** directory is created under the project. The directory contains files such as **libentry/index.d.ts**, **hello.cpp**, and **CMakeLists.txt**.
-
-1. Open the **src/main/cpp/CMakeLists.txt** file, and add **librawfile.z.so** and **libhilog_ndk.z.so** to **target_link_libraries**.
-
-    ```c++
-    target_link_libraries(entry PUBLIC libace_napi.z.so libhilog_ndk.z.so librawfile.z.so)
-    ```
-
-2. Open the **src/main/cpp/types/libentry/index.d.ts** file, and declare the application functions **getFileList**, **getRawFileContent**, and **getRawFileDescriptor**.
-
-    ```c++
-    import resourceManager from '@ohos.resourceManager';
-    export const getFileList: (resmgr: resourceManager.ResourceManager, path: string) => Array<String>;
-    export const getRawFileContent: (resmgr: resourceManager.ResourceManager, path: string) => Uint8Array;
-    export const getRawFileDescriptor: (resmgr: resourceManager.ResourceManager, path: string) => resourceManager.RawFileDescriptor;    
-    ```
-
-3. Modify the source file.
-
-1. Open the **src/main/cpp/hello.cpp** file. During initialization, the file maps the external JavaScript APIs **getFileList**, **getRawFileContent**, and **getRawFileDescriptor** to C++ native APIs **GetFileList**, **GetRawFileContent**, and **GetRawFileDescriptor**.
-
-    ```c++
-    EXTERN_C_START
-    static napi_value Init(napi_env env, napi_value exports)
-    {
-        napi_property_descriptor desc[] = {
-            { "getFileList", nullptr, GetFileList, nullptr, nullptr, nullptr, napi_default, nullptr },
-            { "getRawFileContent", nullptr, GetRawFileContent, nullptr, nullptr, nullptr, napi_default, nullptr },
-            { "getRawFileDescriptor", nullptr, GetRawFileDescriptor, nullptr, nullptr, nullptr, napi_default, nullptr }
-        };
-
-        napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc);
-        return exports;
-    }
-    EXTERN_C_END
-    ```
-
-2. Add the three functions to the **src/main/cpp/hello.cpp** file.
-
-    ```c++
-    static napi_value GetFileList(napi_env env, napi_callback_info info)
-    static napi_value GetRawFileContent(napi_env env, napi_callback_info info)
-    static napi_value GetRawFileDescriptor(napi_env env, napi_callback_info info)
-    ```
-
-3. Obtain JavaScript resource objects from the **hello.cpp** file, and convert them to native resource objects. Then, call the native APIs to obtain the raw file list, raw file content, and raw file descriptor {fd, offset, length}. The sample code is as follows:
-
-    ```c++
-    // Example 1: Use GetFileList to obtain the raw file list.
-    static napi_value GetFileList(napi_env env, napi_callback_info info)
-    {
-        OH_LOG_Print(LOG_APP, LOG_ERROR, GLOBAL_RESMGR, tag, "NDKTest Begin");
-        size_t requireArgc = 3;
-        size_t argc = 2;
-        napi_value argv[2] = { nullptr };
-        // Obtain arguments of the native API.
-        napi_get_cb_info(env, info, &argc, argv, nullptr, nullptr);
-
-        // Obtain argv[0], which specifies conversion of the JavaScript resource object (that is, OH_ResourceManager_InitNativeResourceManager) to a native object.
-        NativeResourceManager *mNativeResMgr = OH_ResourceManager_InitNativeResourceManager(env, argv[0]);
-
-        // Obtain argv[1], which specifies the relative path of the raw file.
-        size_t strSize;
-        char strBuf[256];
-        napi_get_value_string_utf8(env, argv[1], strBuf, sizeof(strBuf), &strSize);
-        std::string dirName(strBuf, strSize);
-
-        // Obtain the corresponding rawDir pointer object.
-        RawDir* rawDir = OH_ResourceManager_OpenRawDir(mNativeResMgr, dirName.c_str());
-
-        // Obtain the number of files and folders in rawDir.
-        int count = OH_ResourceManager_GetRawFileCount(rawDir);
-
-        // Traverse rawDir to obtain the list of file names and save it.
-        std::vector<std::string> tempArray;
-        for(int i = 0; i < count; i++) {
-            std::string filename = OH_ResourceManager_GetRawFileName(rawDir, i);
-            tempArray.emplace_back(filename);
-        }
-
-        napi_value fileList;
-        napi_create_array(env, &fileList);
-        for (size_t i = 0; i < tempArray.size(); i++) {
-            napi_value jsString;
-            napi_create_string_utf8(env, tempArray[i].c_str(), NAPI_AUTO_LENGTH, &jsString);
-            napi_set_element(env, fileList, i, jsString);
-        }
-
-        // Close the rawDir pointer object.
-        OH_ResourceManager_CloseRawDir(rawDir);
-        OH_ResourceManager_ReleaseNativeResourceManager(mNativeResMgr);
-        return fileList;
-    }
-
-    // Example 2: Use rawDir pointer object to obtain the content of the raw file.
-    napi_value CreateJsArrayValue(napi_env env, std::unique_ptr<uint8_t[]> &data, long length)
-    {
-        napi_value buffer;
-        napi_status status = napi_create_external_arraybuffer(env, data.get(), length,

-        }
-        napi_value result = nullptr;
-        status = napi_create_typedarray(env, napi_uint8_array, length, buffer, 0, &result);
-        if (status != napi_ok) {
-            OH_LOG_Print(LOG_APP, LOG_ERROR, GLOBAL_RESMGR, tag, "Failed to create media typed array");
-            return nullptr;

-        return result;

-
-    ```js

-                    let rawfileDescriptor = testNapi.getRawFileDescriptor(this.resmgr, "rawfile1.txt");
-                    console.log("getRawFileDescriptor" + rawfileDescriptor.fd, rawfileDescriptor.offset, rawfileDescriptor.length);

+## How to Develop
+
+The following describes how to obtain the file list in the **rawfile** directory, file content, and FD {fd, offset, length} on the JavaScript side as an example.
+
+1. Create a project.
+
+   ![Creating a C++ application](figures/rawfile1.png)
+
+2. Add dependencies.
+
+   After the project is created, the **cpp** directory is created under the project. The directory contains files such as **libentry/index.d.ts**, **hello.cpp**, and **CMakeLists.txt**.
+
+   1. Open the **src/main/cpp/CMakeLists.txt** file, and add **librawfile.z.so** and **libhilog_ndk.z.so** to **target_link_libraries**.
+
+      ```
+      target_link_libraries(entry PUBLIC libace_napi.z.so libhilog_ndk.z.so librawfile.z.so)
+      ```
+
+      
+
+   2. Open the **src/main/cpp/types/libentry/index.d.ts** file, and declare the application functions **getFileList**, **getRawFileContent**, and **getRawFileDescriptor**.
+
+      ```c++
+      import resourceManager from '@ohos.resourceManager';
+      export const getFileList: (resmgr: resourceManager.ResourceManager, path: string) => Array<String>;
+      export const getRawFileContent: (resmgr: resourceManager.ResourceManager, path: string) => Uint8Array;
+      export const getRawFileDescriptor: (resmgr: resourceManager.ResourceManager, path: string) => resourceManager.RawFileDescriptor;    
+      ```
+
+      
+
+3. Modify the source file.
+
+   1. Open the **src/main/cpp/hello.cpp** file. During initialization, the file maps the external JavaScript APIs **getFileList**, **getRawFileContent**, and **getRawFileDescriptor** to C++ native APIs **GetFileList**, **GetRawFileContent**, and **GetRawFileDescriptor**.
+
+      ```c++
+      EXTERN_C_START
+      static napi_value Init(napi_env env, napi_value exports)
+      {
+          napi_property_descriptor desc[] = {
+              { "getFileList", nullptr, GetFileList, nullptr, nullptr, nullptr, napi_default, nullptr },
+              { "getRawFileContent", nullptr, GetRawFileContent, nullptr, nullptr, nullptr, napi_default, nullptr },
+              { "getRawFileDescriptor", nullptr, GetRawFileDescriptor, nullptr, nullptr, nullptr, napi_default, nullptr }
+          };
+      
+          napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc);
+          return exports;
+      }
+      EXTERN_C_END
+      ```
+
+      
+
+   2. Add the three functions to the **src/main/cpp/hello.cpp** file.
+
+      ```c++
+      static napi_value GetFileList(napi_env env, napi_callback_info info)
+      static napi_value GetRawFileContent(napi_env env, napi_callback_info info)
+      static napi_value GetRawFileDescriptor(napi_env env, napi_callback_info info)
+      ```
+
+      
+
+   3. Obtain JavaScript resource objects from the **hello.cpp** file, and convert them to Native resource objects. Then, call the Native APIs to obtain the file list, file content, and FD {fd, offset, length}. 
+
+      The sample code is as follows:
+
+      ```c++
+      // Example 1: Use GetFileList to obtain the raw file list.
+      static napi_value GetFileList(napi_env env, napi_callback_info info)
+      {
+          OH_LOG_Print(LOG_APP, LOG_ERROR, GLOBAL_RESMGR, tag, "NDKTest Begin");
+          size_t requireArgc = 3;
+          size_t argc = 2;
+          napi_value argv[2] = { nullptr };
+          // Obtain arguments of the native API.
+          napi_get_cb_info(env, info, &argc, argv, nullptr, nullptr);
+      
+          // Obtain argv[0], which specifies conversion of the JavaScript resource object (that is, OH_ResourceManager_InitNativeResourceManager) to a native object.
+          NativeResourceManager *mNativeResMgr = OH_ResourceManager_InitNativeResourceManager(env, argv[0]);
+      
+          // Obtain argv[1], which specifies the relative path of the raw file.
+          size_t strSize;
+          char strBuf[256];
+          napi_get_value_string_utf8(env, argv[1], strBuf, sizeof(strBuf), &strSize);
+          std::string dirName(strBuf, strSize);
+      
+          // Obtain the corresponding rawDir pointer object.
+          RawDir* rawDir = OH_ResourceManager_OpenRawDir(mNativeResMgr, dirName.c_str());
+      
+          // Obtain the number of files and folders in rawDir.
+          int count = OH_ResourceManager_GetRawFileCount(rawDir);
+      
+          // Traverse rawDir to obtain the list of file names and save it.
+          std::vector<std::string> tempArray;
+          for(int i = 0; i < count; i++) {
+              std::string filename = OH_ResourceManager_GetRawFileName(rawDir, i);
+              tempArray.emplace_back(filename);
+          }
+      
+          napi_value fileList;
+          napi_create_array(env, &fileList);
+          for (size_t i = 0; i < tempArray.size(); i++) {
+              napi_value jsString;
+              napi_create_string_utf8(env, tempArray[i].c_str(), NAPI_AUTO_LENGTH, &jsString);
+              napi_set_element(env, fileList, i, jsString);
+          }
+      
+          // Close the rawDir pointer object.
+          OH_ResourceManager_CloseRawDir(rawDir);
+          OH_ResourceManager_ReleaseNativeResourceManager(mNativeResMgr);
+          return fileList;

+# @ohos.secureElement (SE Management)
+
+The **secureElement** module provides APIs for operating and managing the SecureElement (SE). The SE service mentioned in this document is an **SEService** instance. For details, see [newSEService](#secureelementnewseservice).
+
+The instances of the following classes are involved in this document.
+
+| Class   | Description                                          |
+| ------- | ---------------------------------------------- |
+| Session | A **Session** instance represents a session for connecting to an available SE on the device.|
+| Reader  | A **Reader** instance represents an SE reader supported by the device.         |
+| Channel | A **Channel** instance represents an ISO/IEC 7816-4 channel opened to the SE.  |
+
+> **NOTE**
+>
+> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.

+
+## Session.openLogicalChannel
+
+openLogicalChannel(aid: number[], p2: number, callback: AsyncCallback<Channel>):void
+
+Opens a logical channel with the applet represented by the given AID (the AID is not null and the length is not 0).
+
+If the AID length is 0, this API sends a **select** command with the AID length of 0 (as per [GPCS]) to select the Issuer Security Domain of the SE.
+
+If the AID is null, this API sends the **MANAGE CHANNEL Open** only. In this case, the default applet associated with the logical channel is selected.
+
+**P2** is usually **0x00**. The device shall allow any value of **P2** and the following values: **0x00**, **0x04**, **0x08**, **0x0C** as defined in [ISO 7816-4](https://www.iso.org/standard/77180.html).

+# Native API Introduction
+
+Native APIs, also called Native Develop Kit (NDK), are a set of native interfaces and tools provided by the OpenHarmony SDK for implementing key application features by using C or C++. Different from JS APIs, the Native APIs provide only part of underlying capabilities of OpenHarmony, such as the libc, graphics library, window system, multimedia, and compression library. The Native APIs will be build as a dynamic library before being packaged into an application.
+
+## Concepts
+
+|Term|Description|
+|--|--|
+|Native API|Native interfaces, build scripts, and compiler toolchains provided by the **native** package in the OpenHarmony SDK for third-party application development. Native APIs include the C runtime libc, 3D graphics library **OpenGL**, and Node-APIs for cross-language programming between JS and C.|
+|NDK|Native Develop Kit (NDK) that provides the Native APIs in OpenHarmony. NDK is the equivalent of Native API. Native API is the official name.|
+|SDK CAPI|C interfaces and toolchains in OpenHarmony Native APIs.<br/>Currently, OpenHarmony Native APIs contain only C interfaces. Therefore, Native API is CAPI. However, you are advised to use CAPI.|
+|Node-API|Native interfaces that implement cross-language invocation between C and JS. Node-API is formerly called napi. Although OpenHarmony Node-APIs are extension of the Node-APIs provided by **Node.js**, they are not fully compatible with the Node-APIs in **Node.js**.|
+|napi|Former name of Node-API. It is not used because it may be interpreted as Native API or Node-API by mistake. Currently, the interfaces in the Node-API header files still start with **napi_**.|
+
+## Native API Composition
+
+### Native API Directory Structure
+
+Native APIs are stored in the **$(SDK_ROOT)/native** directory of the SDK.
+
+|Directory|Description|
+|--|--|
+|build|Provides the toolchain cmake script used to build the dynamic library of an application. The **ohos.toolchain.cmake** file in this directory defines OpenHarmony cross-compilation options.|
+|build-tools|Provides build tools, such as CMake.|
+|docs|Provides Native API reference documents, which are extracted from the header files using Doxgen.|
+|llvm|Provides the LLVM, a cross compiler that supports the OpenHarmony Application Binary Interface (ABI).|
+|sysroot|Provides dependencies of links, including header files and dynamic libraries.|
+
+### Native APIs
+
+|Category|Description|Introduced Since Version|
+|--|--|--|
+|[C standard library](native-lib/third_party_libc/musl.md)|Provides more than 1500 libc interfaces based on musl.|8|
+|[C++ standard library](native-lib/third_party_libc/cpp.md)|Provides the libc++_shared library for C++ runtime. This library must be packed or statically linked to the application during packing.|8|
+|Log|Provides HiLog interfaces for printing logs to the system.|8|
+|Node-API|Provides APIs like Node-APIs (also called napis) for accessing the JS application environment. Node-APIs are provided by ArkUI and are part of Native APIs.|8|
+|XComponent|Provides Surface and touchscreen event interfaces for developing high-performance graphics applications on ArkUI.|8|
+|libuv|Provides a third-party asynchronous I/O library integrated by ArkUI.|8|
+|libz|Provides basic compression and decompression interfaces.|8|
+|Drawing|Provides a 2D graphics library for drawing on Surface.|8|
+|OpenGL|Provides OpenGL 3.0 interfaces.|8|
+|Rawfile|Provides application resource access interfaces for reading various resources packed in applications.|8|
+|OpenSLES|Provides interfaces for 2D and 3D audio acceleration.|8|
+|Mindspore|Provides AI model interfaces.|9|
+|Bundle management|Provides bundle service interfaces for querying bundle information of applications.|8|
+
+### Native API Documents
+
+* [Native API Reference](native-apis/_o_h___native_x_component.md): provides reference for Native APIs.
+* [Standard Libraries Supported by Native APIs](../reference/native-lib/third_party_libc/musl.md): describes the open-source standard libraries supported by Native APIs.
+* [Native API Development](../napi/napi-guidelines.md): describes how to use Native APIs.
+* [Using NDK to Build a CMake C/C++ Project](../faqs/how-to-migrate-cmake-with-ohosndk.md): describes how to use Native APIs to develop a CMake project.
+* [Using Node-APIs in Application Projects](../napi/napi-guidelines.md): describes how to use Node-APIs.
+
+## How to Use
+
+### Recommended Use of Native APIs
+
+Use Native APIs when you want to:
+
+1. Develop performance-sensitive code in computing-intensive scenarios, such as gaming and physical simulation.
+2. Reuse the existing C or C++ library.
+3. Customize libraries related to CPU features, such as neon acceleration.
+
+### Use of Native APIs Not Recommended
+
+Do not use Native APIs when you want to:
+
+1. Develop a pure OpenHarmony application.
+2. Develop an application that is compatible on as many OpenHarmony devices as possible.
+
+## Debugging Capabilities
+
+1. OpenHarmony provides remote code debugging by using the low-level Debugger (LLDB). For details, see [LLDB](https://gitee.com/openharmony/third_party_llvm-project/blob/master/lldb/README_en.md).
+2. OpenHarmony provides the log debugging for the musl library. For details, see "Debugging Capabilities" in [libc](./native-lib/third_party_libc/musl.md).

+# libc++
+
+Currently, OpenHarmony uses the C++ standard library [(libc++)](https://libcxx.llvm.org/) of the LLVM project.
+
+## Version
+
+From OpenHarmony 3.0, libc++ uses Clang/LLVM 10.0.1.
+
+From OpenHarmony 3.2, libc++ is upgraded to Clang/LLVM 12.0.1.
+
+From OpenHarmony 4.0, libc++ is upgraded to Clang/LLVM 15.0.4.
+
+## Supported Capabilities
+
+The C++11 and C++14 standards are supported, and the C++17 and C++20 standards are on the way. For details about the standards supported by language features, see the corresponding Release Notes at [https://libcxx.llvm.org/](https://libcxx.llvm.org/).
+
+## ABI Compatibility
+In OpenHarmony, both the system library and application native library use the libc++. However, the two libc++ are different. The libc++ of the system library is updated with the image version, while the libc++ of the application native library is updated with the SDK version used for compilation. Both the libc++ libraries cross multiple major versions, which may cause Application Binary Interface (ABI) compatibility issues. To solve this problem, OpenHarmony differentiates the libc++ libraries as follows:
+  * System library: uses **libc++.so**, which is released with the system image.
+  * Application native library: uses **libc++_shared.so**, which is released with the application.
+
+The two libc++ libraries use different namespaces. **libc++_shared.so** uses **__n1** as the namespace for C++ symbols, and **libc++.so** uses **__h** as the namespace for C++ symbols.
+
+> **CAUTION**
+>
+> Currently, the Native API supports C only. The system library can use any programming language.

+The C standard library (libc) provides standard header files and common library implementations (such as input/output processing and string handling) in C language programming.
 
-**Table 1** Standard libraries supported by OpenHarmony
+OpenHarmony uses musl as the libc. musl is a lightweight, fast, simple, and free open-source libc. For details, see [musl libc Reference Manual](http://musl.libc.org/manual.html).
 
-| Library     | Description                                                        |

-- libm: provides basic mathematical functions.
+libdl: provides dynamic linker interfaces such as dlopen. Currently, OpenHarmony provides a link to libdl, and the interfaces are defined in libc.
 
-
-- libdl: provides functions related to dynamic linking, such as **dlopen**.
-
-
-**Version**
+## musl Version
 
 1.2.0
 
-**Capabilities**
-
-C standard library includes a set of header files in accordance with standard C and provides common functions, such as the functions related to input/output (I/O) and string control.
-
-**musl**
-
+From OpenHarmony 4.0, musl 1.2.3 is supported.
+
+## Supported Capabilities
+OpenHarmony provides header files and library interfaces that are compatible (not fully compatible) with C99, C11, and POSIX, and supports Armv7-A, Arm64, and x86_64 architectures.
+
+To better adapt to the basic features of OpenHarmony devices, such as high performance, low memory, high security, lightweight, and multi-form support, OpenHarmony has optimized the musl library and removed the interfaces that are not applicable to embedded devices.
+
+### New Capabilities
+1. The dynamic loader supports isolation by namespace. The dynamic libraries that can be loaded by **dlopen()** are restricted by the system namespace. For example, the system dynamic libraries cannot be opened.
+2. **dlclose()** can be used to unload a dynamic library. This capability is not supported by musl.
+3. The symbol-versioning is supported.
+4. **dlopen()** can directly load uncompressed files in a .zip package.
+
+### Debugging Capabilities
+The libc provides dynamic settings of the basic log functions (disabled by default) for developers to view internal exceptions of the libc. You can set the **param** to enable or disable the log functions, without recompiling the libc. However, you are advised not to use the log functions in official release versions because they affect the running performance.
+
+#### 1. musl.log
+Set **musl.log.enable** to **true** to enable the **musl.log** function. To print other logs, you need to enable this function first.
+```
+setparam musl.log.enable true
+```
+
+#### 2. Loader log function
+The loader starts applications and invokes dlopen() and dlclose() in libc. To view exceptions in the dynamic loading process, enable the loader log function.
+* Enable the loader log of all applications (exercise caution when using this function).
+```
+param set musl.log.ld.app true
+```
+* Enable the loader log of the specified application. {app_name} specifies the target application.
+```
+param set musl.log.ld.all false
+param set musl.log.ld.app.{app_name} true
+```
+* Enable the loader log of all applications except the specified application.
+```
+param set musl.log.ld.all true
+param set musl.log.ld.app.{app_name} false
+```

 ### Development Example
 After completing codec module driver adaptation, use the HDI APIs provided by the codec module for further development. The codec HDI provides the following features:
 
-1. Provides codec HDI APIs for video services to implement encoding and decoding of video services.
-2. Provides standard interfaces for device developers to ensure that the OEM vendors comply with the HDI adapter standard. This promises a healthy evolution of the ecosystem.
+- Provides codec HDI APIs for video services to implement encoding and decoding for video services.
+- Provides standard interfaces for device developers to ensure that the OEM vendors comply with the HDI adapter standard. This promises a healthy evolution of the ecosystem.
 
 The development procedure is as follows:
 
 1. Initialize the driver, including initializing the instances, callbacks, and component.
 2. Set codec parameters and information such as the video width, height, and bit rate.
 3. Apply for input and output buffers.
-4. Flip codec buffers, enable the component to enter the **OMX_Executing** state, and process the callbacks.

 Automatic framing is not supported in rk OMX decoding. Therefore, you need to manually divide data into frames. Currently, data is divided into frames from code 0x000001 or 0x00000001 and sent to the server for processing. The sample code is as follows:
 
 ```cpp
 // Read a file by frame.
-bool OMXCore::ReadOnePacket(FILE* fp, char* buf, uint32_t& nFilled)
+bool CodecHdiDecode::ReadOnePacket(FILE *fp, char *buf, uint32_t &filledCount)

 The codec HDI provides the following callbacks:
 
-- **EventHandler**: Called when a command is executed. For example, when the command for changing the component state from **OMX_StateIdle** to **OMX_StateExecuting** is executed, this callback is invoked to return the result.
-- **EmptyBufferDone**: Called when the input data is consumed. If the client needs to fill in data to encode or decode, call **EmptyThisBuffer()**.
-- **FillBufferDone**: Called when the output data is filled. If the client needs to read the encoded or decoded data, call **FillThisBuffer()**.
+- **EventHandler**: Called when a command is executed. For example, when the command for changing the component state from **CODEC_STATE_IDLE** to **CODEC_STATE_EXECUTING** is executed, this callback is invoked to return the result.
+- **EmptyBufferDone**: Called when the input data is consumed. If the client needs to fill data to encode or decode, it must call **EmptyThisBuffer()** again.

 ## Overview
 
-### WLAN
+### Function
 
-The Wireless Local Area Network (WLAN) driver module is developed based on OpenHarmony Hardware Driver Foundation (HDF). It supports modular assembly and building, automatic adaptation to device differences, and cross-OS porting.
+A wireless LAN (WLAN) allows users to easily connect to a wireless network to transmit and share data and move around within the area and remain connected to the network. The WLAN driver developed based on the Hardware Driver Foundation (HDF) shields hardware component differences and provides stable basic capability interfaces for upper-layer WLAN services, including starting a scan, associating with or disassociating from a hotspot, obtaining or setting MAC addresses, and obtaining link information.
 
-### Working Principles
-
-You can modify your driver code based on the unified APIs provided by the WLAN module. The WLAN module provides:
-
-- APIs for the underlying layer to implement capabilities, such as opening or closing a WLAN hotspot, scanning hotspots, and connecting to or disconnecting from a hotspot.
-- APIs for the Hardware Device Interface (HDI) layer to implement capabilities, such as setting or obtaining the device Media Access Control (MAC) address and setting the transmit power.
-
-The following figure shows the WLAN architecture. The WLAN driver module implements startup loading, parses configuration files, and provides bus abstraction APIs. The WLAN chip driver module provides the MAC Sublayer Management Entity (MLME).
-
-  **Figure 1** WLAN architecture
-
-  ![image](figures/WLAN_architecture.png "WLAN architecture")
+### Basic Concepts
 
-  The following figure shows the WLAN driver architecture.
+Before development, you need to understand the following basic concepts related to WLAN:
 
-  **Figure 2** WLAN driver architecture
+- AP
+  
+  A wireless access point (AP) is a central node of a network that provides the wireless access service. Once connecting to the wireless network, the device can access data.
 
-  ![image](figures/WLAN_driver_architecture.png "WLAN driver architecture")
+- STA
+  
+  A station (STA) is a basic component of a WLAN. Each terminal connected to a WLAN, such as a notebook and a personal digital assistant (PDA), is an STA.
 
-The WLAN driver consists of the following modules:
+- SSID
+  
+  A service set identifier (SSID) identifies a wireless network. Each WLAN has its SSID.
 
-1. WLAN Message: provides an independent interface for each service or a composite service interface for multiple dependent services. It can run in the user mode, kernel mode, and MCU to implement complete decoupling between components.
+- bssid
+  
+  A basic service set identifier (BSSID) is a 48-bit MAC address that uniquely identifies a basic service set on a WLAN.
+  
+- Scan
 
-2. WLAN Configuration Core: parses WLAN configuration files.
+  A terminal device scans the wireless network to obtain visible wireless network information, including the hotspot SSID, operating frequency band, and signal strength.
 
-3. Access point (AP): allows devices to connect to the WLAN.
+- Associate
 
-4. Station (STA): a device that has access to the WLAN system and allows transmission and reception of data.
+  When a terminal device is associated with a valid hotspot, it can communicate with the AP. A device (STA) can set up a connection with only one AP at a time.
 
-5. mac80211: defines MAC-layer APIs for underlying drivers.
-
-6. Bus: provides a unified bus abstract interface for the upper layer. It shields the differences between different kernels by calling the Secure Digital Input Output (SDIO) interfaces provided by the platform layer and encapsulating the adapted USB and PCIe interfaces. It also encapsulates different types of bus operations in a unified manner to shield differences between different chipsets. The complete bus driving capabilities provided by the bus module help simplify and streamline the development of different chip vendors.
-
-7. NetDevice: creates dedicated network devices to shield differences between OSs, provides unified interfaces for Wi-Fi drivers, unified HDF NetDevice data structure, and unified management, registration, and deregistration capabilities, and connects to the Linux network device layer on mini-, small-, standard, and large-system devices.
-
-8. NetBuf: encapsulates the unified data structure of the Linux or LiteOS native network data buffer and the operation interfaces for network data.
+### Working Principles
 
-9. FlowCtl: processes data based on the priority when the data volume is too large.
+This document describes how to develop WLAN functions based on the HDF. The following figure shows the WLAN framework.
 
-10. HCC-CFG: configures WLAN parameters, including the board configuration, driver configuration, and module configuration.
+![image](figures/WLAN-driver-framework.png "WLAN Framework")
 
-The relationships between the main modules are as follows:
+1. The upper-layer service calls a hardware device interface (HDI) based on service requirements to deliver user-mode messages to the client through the Wi-Fi Protected Access (WPA) layer or hardware abstraction layer (HAL). The WPA layer provides interfaces for setting the encryption mode, associating with a hotspot, setting a channel, and hiding the hotspot. As a supplement to the WPA layer, the HAL provides APIs for setting the country code or MAC address and obtaining channel information.
+   
+2. The Message module distributes user-mode messages to modules, such as the AP and STA, by component.
+   
+3. Hdf_Mac80211 defines MAC-layer interfaces for underlying drivers. The command field is delivered to Hdf_Mac80211 and then sent to the WLAN chip firmware through the Bus module.
+   
+4. The Bus module provides unified bus abstraction interfaces for the upper layer. It shields the differences between kernels by calling the Secure Digital Input Output (SDIO) interfaces provided by the platform layer and encapsulating the USB and PCIe interfaces. The Bus module also encapsulates different types of bus operations in a unified manner to shield differences between chipsets. The interfaces provided by the Bus module simplify and streamline the development of different chip vendors.
+   
+5. Extensible Authentication Protocol (EAP) over LAN (EAPOL) is a LAN-based extended authentication protocol. It is used to transmit EAP packets between a client and a device (access device or server) so that EAP packets can be transmitted on a LAN to complete the authentication process and enable the device to go online.
+   
+6. NetDevice creates dedicated network devices to shield differences between OSs. It provides unified interfaces for Wi-Fi drivers, unified HDF NetDevice data structs, and unified management, registration, and deregistration capabilities, and connects to the Linux network device layer on OpenHarmony devices.
+   
+7. NetBuf encapsulates the unified data structure of the Linux or LiteOS native network data buffer and the operation interfaces for network data.
+   
+8. The protocol stack works with the NetDevice and NetBuf modules to exchange data flows.
 
-1. The WLAN driver works with HCC-CFG and WLAN Configuration Core to parse and load configuration files.
+### Constraints
 
-2. The WLAN Message module distributes user-mode messages to the AP and STA by component.
+The WLAN driver provides basic capability interfaces for upper-layer WLAN services. The HDI interfaces apply to the standard system, and the HAL interfaces apply to mini and small systems.
 
-3. Commands are delivered to mac80211, and then forwarded by the Bus module to the WLAN chip firmware.
+## Development Guidelines
 
-4. The protocol stack works with the NetDevice, NetBuf, and FlowCtl modules to exchange data flows.
+### When to Use
 
-## How to Develop
+The WLAN driver provides basic capability interfaces for upper-layer WLAN services to ensure that users can easily access the wireless network and transmit and share data. Refer to the following when you adapt your WLAN module to OpenHarmony.

-### Development Procedure
-#### WLAN Framework Adaptation
-
-The WLAN driver framework developed based on the HDF and Platform framework provides a unified driver model regardless of the OS and system on a chip (SoC). When developing your WLAN driver, you need to configure data based on the WLAN driver framework.
-**Development Procedure**
-
-1. Configure hardware (such as modules and chips) parameters in the **wlan_platform.hcs** file. The HDF parses the file to generate structure objects with full configuration.
-
-2. Implement initialization and deinitialization of the WLAN module (such as initialize and deinitialize the WLAN chip and WLAN chip driver).

+#### Initializing and deinitializing the WLAN Chip and WLAN Chip Driver
+
+   - Implement the driver adaptation entry function
 
      Define a variable of the HdfDriverEntry type based on the chip to hook functions of **Bind()**, **Init()**, and **Release()**. Call **HDF_INIT** to register the driver entry with the HDF. During driver loading, the HDF calls the **Bind** function and then the **Init** function to load the driver. If **Init()** fails to be called, the HDF calls **Release()** to release driver resources.

 Smartperf-Host是一款深入挖掘数据、细粒度地展示数据的性能功耗调优工具，旨在为开发者提供一套性能调优平台，支持对CPU调度、频点、进程线程时间片、堆内存、帧率等数据进行采集和展示，展示方式为泳道图，支持GUI（图形用户界面）操作进行详细数据分析。
 ## 架构图
 ![系统架构图](figures/smartperf_frame.png)
+
 该组件整体分为设备端和PC端两部分，设备端和PC端基于gRPC（Remote Procedure Call）通信框架进行数据交互。
 
 设备端内部分为应用程序内嵌组件、命令行工具、性能调优服务、性能调优插件集合、部分系统工具及部分系统内核等模块。设备端提供了插件扩展能力，对外提供了插件接口，基于该扩展能力可以按需定义自己的能力，并集成到框架中来，目前基于插件能力已经完成了native内存插件、trace插件等，详细介绍见[性能调优组件](https://gitee.com/openharmony/developtools_profiler)。

+
+**getFileAssets接口获取文件资源兼容性影响：**
+
+在API version 10上，摒弃了物理目录作为相册的设计，采用了逻辑相册的设计，一个相册中可以添加多个文件，一个文件也可以在多个相册中呈现。新的设计将带来parent、albumId、albumUri和albumName属性使用上的不兼容，无法作为MediaFetchOptions的参数在getFileAssets接口中使用。下面示例代码为错误示例：
+
+1. 使用[getMediaLibrary](../../../application-dev/reference/apis/js-apis-medialibrary.md#medialibrarygetmedialibrary)接口获取媒体库实例。
+2. 创建检索条件[MediaFetchOptions](../../../application-dev/reference/apis/js-apis-medialibrary.md#mediafetchoptions7)。
+3. 调用[getFileAssets](../../../application-dev/reference/apis/js-apis-medialibrary.md#getfileassets7)接口获取文件资源。
+
+**错误示例：**
+
+```js
+import mediaLibrary from '@ohos.multimedia.mediaLibrary';
+
+async function example() {
+  try {
+    let context = getContext(this);
+    let media = mediaLibrary.getmediaLibrary(context);
+    let fileKeyObj = mediaLibrary.FileKey;
+    let albumId = 1;
+    let getImageOp = {
+      selections: fileKeyObj.ALBUM_ID + '= ?', // 使用parent、albumId、albumUri和albumName属性查询均无法获取文件资源。
+      selectionArgs: [albumId.toString()],
+    };
+    const fetchFileResult = await media.getFileAssets(getImageOp); // 查询失败，获取的fetchFileResult为空。
+    const fileAsset = await fetchFileResult.getFirstObject();
+    console.info('mediaLibrary fileAsset displayName: ' + fileAsset.displayName);
+  } catch (err) {
+    console.error('mediaLibrary fail, err: ' + err);
+  }
+}
+```
+
+推荐使用以下方式调用getFileAssets接口获取文件资源：
+
+**正确示例：**
+
+```js
+import mediaLibrary from '@ohos.multimedia.mediaLibrary';
+
+async function example() {
+  try {
+    let context = getContext(this);
+    let media = mediaLibrary.getmediaLibrary(context);
+    let fileKeyObj = mediaLibrary.FileKey;
+    let imageType = mediaLibrary.MediaType.IMAGE;
+    let getImageOp = {
+      selections: fileKeyObj.MEDIA_TYPE + '= ?',
+      selectionArgs: [imageType.toString()],  // 查询所有图片类型的文件。
+    };
+    const fetchFileResult = await media.getFileAssets(getImageOp); 
+    const fileAsset = await fetchFileResult.getFirstObject();
+    console.info('mediaLibrary fileAsset displayName: ' + fileAsset.displayName);
+  } catch (err) {
+    console.error('mediaLibrary fail, err: ' + err);
+  }
+}
+```
+
+**createAsset接口创建相册兼容性影响：**
+
+由于API version 10的SDK上relativePath和相册没有关联关系，文件创建成功后，relativePath的最后一级目录不会作为相册呈现。
+
+**getAlbums接口获取相册兼容性影响：**
+
+由于API version 10的SDK上relativePath和相册没有关联关系，在使用getAlbums时不支持relativePath作为查询条件，并且ALBUM_NAME参数只能使用"Camera"和"Screenshots"。下面示例代码为错误示例：
+
+1. 使用[getMediaLibrary](../../../application-dev/reference/apis/js-apis-medialibrary.md#medialibrarygetmedialibrary)接口获取媒体库实例。
+2. 创建相册检索条件[MediaFetchOptions](../../../application-dev/reference/apis/js-apis-medialibrary.md#mediafetchoptions7)。
+3. 调用[getAlbums](../../../application-dev/reference/apis/js-apis-medialibrary.md#getalbums7)接口获取相册。
+
+**错误示例：**
+
+```js
+import mediaLibrary from '@ohos.multimedia.mediaLibrary';
+
+async function example() {
+  try {
+    let context = getContext(this);
+    let media = mediaLibrary.getmediaLibrary(context);
+    let AlbumNoArgsfetchOp = {
+      selections: mediaLibrary.FileKey.ALBUM_NAME + ' = ?',
+      selectionArgs: ['新建相册1'], // 获取albumName为新建相册1的相册。
+    };
+    const fetchFileResult = await media.getAlbums(AlbumNoArgsfetchOp); // 查询失败，获取的fetchFileResult为空。
+    const album = await fetchFileResult.getFirstObject();
+    console.info('mediaLibrary album albumName: ' + album.albumName);
+  } catch (err) {
+    console.error('mediaLibrary fail, err: ' + err);
+  }
+}
+```
+
+使用如下示例代码可以获取Camera和Screenshots相册。
+
+**正确示例：**
+
+```js
+import mediaLibrary from '@ohos.multimedia.mediaLibrary';
+
+async function example() {
+  try {
+    let context = getContext(this);
+    let media = mediaLibrary.getmediaLibrary(context);
+    let AlbumNoArgsfetchOp = {
+      selections: mediaLibrary.FileKey.ALBUM_NAME + ' = ? OR ' + mediaLibrary.FileKey.ALBUM_NAME + ' = ?',
+      selectionArgs: ['Camera', 'Screenshots'], // 获取相机相册和截屏录屏相册。
+    };
+    const fetchFileResult = await media.getAlbums(AlbumNoArgsfetchOp);
+    const album = await fetchFileResult.getFirstObject();
+    console.info('mediaLibrary album albumName: ' + album.albumName);
+  } catch (err) {
+    console.error('mediaLibrary fail, err: ' + err);
+  }
+}
+```
+
+**FileAsset.commitModify接口获取相册兼容性影响：**
+
+在API version 10的SDK上去掉了针对audio无意义的orientation属性，在使用commitModify接口时将无法对audio资源的orientation属性进行修改。
