 ## IDL Overview
 To ensure successful communications between the client and server, interfaces recognized by both parties must be defined. The OpenHarmony Interface Definition Language (IDL) is a tool for defining such interfaces. OpenHarmony IDL decomposes objects to be transferred into primitives that can be understood by the operating system and encapsulates cross-boundary objects based on developers' requirements.

 ### Specifications for Compiling IDL Files
 Only one interface type can be defined in an IDL file, and the interface name must be the same as the file name. The interface definition of the IDL file is described in Backus-Naur form (BNF). The basic definition format is as follows:
 ```
 [<*interface_attr_declaration*>]interface<*interface_name_with_namespace*>{<*method_declaration*>}
 ```
 In the preceding information, <*interface_attr_declaration*> declares interface attributes. Currently, only the **oneway** attribute is supported, indicating that all methods in the interface are unidirectional. Such a method returns value without waiting for the execution to complete. This attribute is optional. If this attribute is not set, synchronous call is used. The interface name must contain the complete interface header file directory, namespace, and method declaration. Empty interfaces are not allowed.
 The method declaration format in the interface is as follows:
 ```
 [<*method_attr_declaration*>]<*result_type*><*method_declaration*>
 ```
 In the preceding information, <*method_attr_declaration*> describes the interface attributes. Currently, only the **oneway** attribute is supported, indicating that the method is unidirectional. Such a method returns value without waiting for the execution to complete. This attribute is optional. If this attribute is not set, synchronous call is used. <*result_type*> indicates the type of the return value, and <*method_declaration*> indicates the method name and parameter declaration.
 The parameter declaration format is as follows:
 ```
 [<*formal_param_attr*>]<*type*><*identifier*>
 ```
 The value of <*formal_param_attr*> can be **in**, **out**, or **inout**, indicating that the parameter is an input parameter, an output parameter, or both an input and an output parameter, respectively. A **oneway** method does not allow **output** or **inout** parameters or return values.

For example, for **IIdlTestService.idl**, the generated files are **i_idl_test_service.h**, **idl_test_service_proxy.h**, **idl_test_service_stub.h**, **idl_test_service_proxy.cpp**, and **idl_test_service_stub.cpp**.
+You can run the **./idl -gen-cpp -d dir -c dir/iTest.idl** command (**-d** indicates the output directory) to generate the interface file, stub file, and proxy file in the **dir** directory in the execution environment.

 ## Widget Overview
 A widget is a set of UI components used to display important information or operations for an application. It provides users with direct access to a desired application service, without requiring them to open the application.
-A widget displays brief information about an application on the UI of another application (host application, currently system applications only) and provides basic interactive features such as opening a UI page or sending a message. The widget host is responsible for displaying the widget.
+A widget displays brief information about an application on the UI of another application (host application, currently system applications only) and provides basic interactive functions such as opening a UI page or sending a message.  
 Basic concepts:
- Widget provider
+- Widget provider: an atomic service that controls what and how content is displayed in a widget and interacts with users.
+- Widget host: an application that displays the widget content and controls the position where the widget is displayed in the host application.
-  The widget provider is an atomic service that provides the content to be displayed. It controls the display content, component layout, and component click events of a widget.
+- Widget Manager: a resident agent that manages widgets added to the system and provides functions such as periodic widget update.

 > The widget host and provider do not keep running all the time. The Widget Manager starts the widget provider to obtain widget information when a widget is added, deleted, or updated.
 You only need to develop widget content as the widget provider. The system automatically handles the work done by the widget host and Widget Manager.
 The widget provider controls the widget content to display, component layout, and click events bound to components.

+- Normal widget: a widget that will be persistently used by the widget host
-Temporary widget: a widget that is temporarily used by the widget host
+- Temporary widget: a widget that is temporarily used by the widget host
 Data of a temporary widget is not persistently stored. If the widget framework is killed and restarted, data of a temporary widget will be deleted. However, the widget provider is not notified of which widget is deleted, and still keeps the data. Therefore, the widget provider should implement data clearing. In addition, the widget host may convert a temporary widget into a normal one. If the conversion is successful, the widget provider should process the widget ID and store the data persistently. This prevents the widget provider from deleting persistent data when clearing temporary widgets.

 # Ability Development
 ## When to Use
-Unlike the FA model, the [stage model](stage-brief.md) requires you to declare the application package structure in the `module.json` and `app.json` files during application development. For details about the configuration file, see [Application Package Structure Configuration File](../quick-start/stage-structure.md).

+- Create an ability that supports screen viewing and human-machine interaction. You must implement the following scenarios: ability lifecycle callbacks, obtaining ability configuration, requesting permissions, and notifying environment changes.
 - Start an ability. You need to implement ability startup on the same device, on a remote device, or with a specified UI page.
 - Call abilities. For details, see [Call Development](stage-call.md).
 - Connect to and disconnect from a Service Extension ability. For details, see [Service Extension Ability Development](stage-serviceextension.md).
 - Continue the ability on another device. For details, see [Ability Continuation Development](stage-ability-continuation.md).

 ### Requesting Permissions
-If an application needs to obtain user privacy information or use system capabilities, for example, obtaining location information or using the camera to take photos or record videos, it must request the permission from consumers. During application development, you need to specify the involved sensitive permissions, declare the required permissions in `module.json`, and use the `requestPermissionsFromUser` API to request the permission from consumers in the form of a dialog box.

 ### Notifying of Environment Changes
-Environment changes include changes of global configurations and ability configurations. Currently, the global configurations include the system language and color mode. The change of global configurations is generally triggered by the configuration item in **Settings** or the icon in **Control Panel**. The ability configuration is specific to a single `Ability` instance, including the display ID, screen resolution, and screen orientation. The configuration is related to the display where the ability is located, and the change is generally triggered by the window. For details on the configuration, see [Configuration](../reference/apis/js-apis-configuration.md).

 ### Starting an Ability with the Specified Page
 If the launch type of an ability is set to `singleton` and the ability has been started, the `onNewWant` callback is triggered when the ability is started again. You can pass start options through the `want`. For example, to start an ability with the specified page, use the `uri` or `parameters` parameter in the `want` to pass the page information. Currently, the ability in the stage model cannot directly use the `router` capability. You must pass the start options to the custom component and invoke the `router` method to display the specified page during the custom component lifecycle management. The sample code is as follows:

-To implement multi-device-form tailoring and multi-window scalability, OpenHarmony decouples the component manager from the window manager. The ability lifecycle defined in the stage model includes only the creation, destruction, foreground, and background states. The gain focus and lose focus states that are closely related to UI content are defined in the window stage. This implements weak coupling between the abilities and windows. On the service side, the window manager notifies the component manager of the foreground and background changes, so the component manager only senses the foreground and background changes but not the focus changes.

 ## How to Develop
 The following example shows how to implement a distributed data object synchronization.
 1. Import the @ohos.data.distributedDataObject module to the development environment.
+   ```js   
-   ```js
+   import distributedObject from '@ohos.data.distributedDataObject';   
-   import distributedObject from '@ohos.data.distributedDataObject'
   ```
+2. Request the permission. <br>Add the required permission in the **config.json** file. The sample code is as follows:
+    ```
+     {
+       "module": {
+           "reqPermissions": [
+               {
+                  "name": "ohos.permission.DISTRIBUTED_DATASYNC"
+               }
+           ]
+       }
+     }
+    ```
+    This permission must also be authorized by the user through a dialog box when the application is started for the first time. The sample code is as follows:
+    ```js
+    import featureAbility from '@ohos.ability.featureAbility';
+    function grantPermission() {
+        console.info('grantPermission');
+        let context = featureAbility.getContext();
+        context.requestPermissionsFromUser(['ohos.permission.DISTRIBUTED_DATASYNC'], 666, function (result) {
+            console.info(`result.requestCode=${result.requestCode}`)

-   **Sampling**
+- **Sampling rate**
+  Sampling rate is the number of samples extracted from a continuous signal per second to form a discrete signal. It is measured in Hz. Generally, human hearing range is from 20 Hz to 20 kHz. Common audio sampling rates include 8 kHz, 11.025 kHz, 22.05 kHz, 16 kHz, 37.8 kHz, 44.1 kHz, 48 kHz, 96 kHz, and 192 kHz.
-    Sampling is a process to obtain discrete-time signals by extracting samples from analog signals in a continuous time domain at a specific interval.
+- **Channel**
+  Channels refer to different spatial positions where independent audio signals are recorded or played. The number of channels is the number of audio sources used during audio recording, or the number of speakers used for audio playback.

-    Audio data is in stream form. For the convenience of audio algorithm processing and transmission, it is generally agreed that a data amount in a unit of 2.5 to 60 milliseconds is one audio frame. This unit is called sampling time, and its length is specific to codecs and the application requirements.
-   **PCM**
-    Pulse code modulation \(PCM\) is a method used to digitally represent sampled analog signals. It converts continuous-time analog signals into discrete-time digital signal samples.

+# Drawing Development
+## When to Use
+The Native Drawing module provides APIs for drawing 2D graphics and text. The following scenarios are common for drawing development:
+* Drawing 2D graphics
+* Drawing and painting text
+## Available APIs
+| API| Description|
+| -------- | -------- |
+| OH_Drawing_BitmapCreate (void) | Creates a bitmap object.|
+| OH_Drawing_BitmapBuild (OH_Drawing_Bitmap *, const uint32_t width, const uint32_t height, const OH_Drawing_BitmapFormat *) | Initializes the width and height of a bitmap object and sets the pixel format for the bitmap.|
+| OH_Drawing_CanvasCreate (void) | Creates a canvas object.|
+| OH_Drawing_CanvasBind (OH_Drawing_Canvas *, OH_Drawing_Bitmap *) | Binds a bitmap to a canvas so that the content drawn on the canvas is output to the bitmap (this process is called CPU rendering).|

+## Development Procedure for 2D Graphics Drawing
+The following steps describe how to use the canvas and brush of the Native Drawing module to draw a 2D graphics.
+1. **Create a bitmap object.** Use `OH_Drawing_BitmapCreate` in `drawing_bitmap.h` to create a bitmap object (named `cBitmap` in this example), and use `OH_Drawing_BitmapBuild` to specify its length, width, and pixel format.
+    ```c++
+    // Create a bitmap object.
+    OH_Drawing_Bitmap* cBitmap = OH_Drawing_BitmapCreate();
+    // Define the pixel format of the bitmap.
+    OH_Drawing_BitmapFormat cFormat {COLOR_FORMAT_RGBA_8888, ALPHA_FORMAT_OPAQUYE};
+    // Set the pixel format for the bitmap.
+    OH_Drawing_BitmapBuild(cBitmap, width, height, &cFormat);
+    ```
+2. **Create a canvas object.** Use `OH_Drawing_CanvasCreate` in `drawing_canvas.h` to create a canvas object (named `cCanvas` in this example), and use `OH_Drawing_CanvasBind` to bind `cBitmap` to this canvas. The content drawn on the canvas will be output to the bound `cBitmap` object.
+    ```c++
+    // Create a canvas object.
+    OH_Drawing_Canvas* cCanvas = OH_Drawing_CanvasCreate();
+    // Bind the bitmap to the canvas. The content drawn on the canvas will be output to the bound bitmap memory.
+    OH_Drawing_CanvasBind(cCanvas, cBitmap);
+    // Use white to clear the canvas.
+    OH_Drawing_CanvasClear(cCanvas, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0xFF, 0xFF));
+    ```
+3. **Construct a shape.** Use the APIs provided in `drawing_path.h` to draw a pentagram `cPath`.
+    ```c++
+    int len = 300;
+    float aX = 500;
+    float aY = 500;
+    float dX = aX - len * std::sin(18.0f);
+    float dY = aY + len * std::cos(18.0f);
+    float cX = aX + len * std::sin(18.0f);
+    float cY = dY;
+    float bX = aX + (len / 2.0);
+    float bY = aY + std::sqrt((cX - dX) * (cX - dX) + (len / 2.0) * (len / 2.0));
+    float eX = aX - (len / 2.0);
+    float eY = bY;
+    // Create a path object and use the APIs to draw a pentagram.
+    OH_Drawing_Path* cPath = OH_Drawing_PathCreate();
+    // Specify the start point of the path.
+    OH_Drawing_PathMoveTo(cPath, aX, aY);
+    // Draw a line segment from the last point of a path to the target point.
+    OH_Drawing_PathLineTo(cPath, bX, bY);
+    OH_Drawing_PathLineTo(cPath, cX, cY);
+    OH_Drawing_PathLineTo(cPath, dX, dY);
+    OH_Drawing_PathLineTo(cPath, eX, eY);
+    // Close the path. Now the path is drawn.
+    OH_Drawing_PathClose(cPath);
+    ```
+4. **Set the brush and pen styles.** Use `OH_Drawing_PenCreate` in `drawing_pen.h` to create a pen (named `cPen` in this example), and set the attributes such as the anti-aliasing, color, and thickness. The pen is used to outline a shape. Use `OH_Drawing_BrushCreate` in `drawing_brush.h` to create a brush (named `cBrush` in this example), and set the brush color. The brush is used to fill in a shape. Use `OH_Drawing_CanvasAttachPen` and `OH_Drawing_CanvasAttachBrush` in `drawing_canvas.h` to attach the pen and brush to the canvas.
+    ```c++
+    // Create a pen object and set the anti-aliasing, color, and thickness.
+    OH_Drawing_Pen* cPen = OH_Drawing_PenCreate();
+    OH_Drawing_PenSetAntiAlias(cPen, true);
+    OH_Drawing_PenSetColor(cPen, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0x00, 0x00));
+    OH_Drawing_PenSetWidth(cPen, 10.0);
+    OH_Drawing_PenSetJoin(cPen, LINE_ROUND_JOIN);
+    // Attach the pen to the canvas.
+    OH_Drawing_CanvasAttachPen(cCanvas, cPen);
+    // Create a brush object and set the color.
+    OH_Drawing_Brush* cBrush = OH_Drawing_BrushCreate();
+    OH_Drawing_BrushSetColor(cBrush, OH_Drawing_ColorSetArgb(0xFF, 0x00, 0xFF, 0x00));
+    // Attach the brush to the canvas.
+    OH_Drawing_CanvasAttachBrush(cCanvas, cBrush);
+    ```
+5. **Draw a shape.** Use `OH_Drawing_CanvasDrawPath` in `drawing_canvas.h` to draw a pentagram on the canvas. Call the corresponding APIs to destroy the objects when they are no longer needed.
+    ```c++
+    // Draw a pentagram on the canvas. The outline of the pentagram is drawn by the pen, and the color is filled in by the brush.
+    OH_Drawing_CanvasDrawPath(cCanvas, cPath);
+    // Destroy the created objects when they are no longer needed.
+    OH_Drawing_BrushDestory(cBrush);
+    OH_Drawing_PenDestory(cPen);
+    OH_Drawing_PathDestory(cPath);
+    ```
+6. **Obtain pixel data.** Use `OH_Drawing_BitmapGetPixels` in `drawing_bitmap.h` to obtain the pixel address of the bitmap bound to the canvas. The memory to which the address points contains the pixel data of the drawing on the canvas.
+    ```c++
+    // Obtain the pixel address after drawing. The memory to which the address points contains the pixel data of the drawing on the canvas.
+    void* bitmapAddr = OH_Drawing_BitmapGetPixels(cBitmap);
+    auto ret = memcpy_s(addr, addrSize, bitmapAddr, addrSize);
+    if (ret != EOK) {
+        LOGI("memcpy_s failed");
+    }
+    // Destroy the canvas object.
+    OH_Drawing_CanvasDestory(cCanvas);
+    // Destroy the bitmap object.
+    OH_Drawing_BitmapDestory(cBitmap);
+    ```
+## Development Procedure for Text Drawing and Display
+The following steps describe how to use the text drawing and display feature of the Native Drawing module.
+1. **Create a canvas and a bitmap.**
+    ```c++
+    // Create a bitmap.
+    OH_Drawing_Bitmap* cBitmap = OH_Drawing_BitmapCreate();
+    OH_Drawing_BitmapFormat cFormat {COLOR_FORMAT_RGBA_8888, ALPHA_FORMAT_OPAQUE};
+    OH_Drawing_BitmapBuild(cBitmap, width, height, &cFormat);
+    // Create a canvas.
+    OH_Drawing_Canvas* cCanvas = OH_Drawing_CanvasCreate();
+    OH_Drawing_CanvasBind(cCanvas, cBitmap);
+    OH_Drawing_CanvasClear(cCanvas, OH_Drawing_ColorSetArgb(0xFF, 0xFF, 0xFF, 0xFF));
+    ```
+2. **Set the typography style.**
+    ```c++
+    // Set the typography attributes such as left to right (LTR) for the text direction and left-aligned for the text alignment mode.
+    OH_Drawing_TypographyStyle* typoStyle = OH_Drawing_CreateTypographyStyle();
+    OH_Drawing_SetTypographyTextDirection(typoStyle, TEXT_DIRECTION_LTR);
+    OH_Drawing_SetTypographyTextAlign(typoStyle, TEXT_ALIGN_LEFT);
+    ```
+3. **Set the text style.**
+    ```c++
+    // Set the text color, for example, black.
+    OH_Drawing_TextStyle* txtStyle = OH_Drawing_CreateTextStyle();
+    OH_Drawing_SetTextStyleColor(txtStyle, OH_Drawing_ColorSetArgb(0xFF, 0x00, 0x00, 0x00));
+    // Set text attributes such as the font size and weight.
+    double fontSize = 30;
+    OH_Drawing_SetTextStyleFontSize(txtStyle, fontSize);
+    OH_Drawing_SetTextStyleFontWeight(txtStyle, FONT_WEIGHT_400);
+    OH_Drawing_SetTextStyleBaseLine(txtStyle, TEXT_BASELINE_ALPHABETIC);
+    OH_Drawing_SetTextStyleFontHeight(txtStyle, 1);
+    // Set the font families.
+    const char* fontFamilies[] = {"Roboto"};
+    OH_Drawing_SetTextStyleFontFamilies(txtStyle, 1, fontFamilies);
+    OH_Drawing_SetTextStyleFontStyle(txtStyle, FONT_STYLE_NORMAL);
+    OH_Drawing_SetTextStyleLocale(txtStyle, "en");
+    ```
+4. **Generate the final text display effect.**
+    ```c++
+    OH_Drawing_TypographyCreate* handler = OH_Drawing_CreateTypographyHandler(typoStyle,
+        OH_Drawing_CreateFontCollection());
+    OH_Drawing_TypographyHandlerPushTextStyle(handler, txtStyle);
+    // Set the text content.
+    const char* text = "OpenHarmony\n";
+    OH_Drawing_TypographyHandlerAddText(handler, text);
+    OH_Drawing_TypographyHandlerPopTextStyle(handler);
+    OH_Drawing_Typography* typography = OH_Drawing_CreateTypography(handler);
+    // Set the maximum width.
+    double maxWidth = 800.0;
+    OH_Drawing_TypographyLayout(typography, maxWidth);
+    // Set the start position for text display.
+    double position[2] = {10.0, 15.0};
+    OH_Drawing_TypographyPaint(typography, cCanvas, position[0], position[1]);
+    ```

+# NativeWindow Development
+## When to Use
+`NativeWindow` is a local platform window of OpenHarmony. It provides APIs for you to create a native window from `Surface`, create a native window buffer from `SurfaceBuffer`, and request and flush a buffer.
+The following scenarios are common for native window development:
+* Drawing content using native C++ code and displaying the content on the screen
+* Requesting and flushing a buffer when adapting to EGL `eglswapbuffer`
+## Available APIs
+| API| Description|
+| -------- | -------- |
+| OH_NativeWindow_CreateNativeWindowFromSurface (void \*pSurface) | Creates a `NativeWindow` instance. A new `NativeWindow` instance is created each time this function is called.|
+| OH_NativeWindow_DestroyNativeWindow (struct NativeWindow \*window) | Decreases the reference count of a `NativeWindow` instance by 1 and, when the reference count reaches 0, destroys the instance.|
+| OH_NativeWindow_CreateNativeWindowBufferFromSurfaceBuffer (void \*pSurfaceBuffer) | Creates a `NativeWindowBuffer` instance. A new `NativeWindowBuffer` instance is created each time this function is called.|
+| OH_NativeWindow_DestroyNativeWindowBuffer (struct NativeWindowBuffer \*buffer) | Decreases the reference count of a `NativeWindowBuffer` instance by 1 and, when the reference count reaches 0, destroys the instance.|
+| OH_NativeWindow_NativeWindowRequestBuffer (struct NativeWindow \*window struct NativeWindowBuffer \*\*buffer, int \*fenceFd) | Requests a `NativeWindowBuffer` through a `NativeWindow` instance for content production.|
+| OH_NativeWindow_NativeWindowFlushBuffer (struct NativeWindow \*window, struct NativeWindowBuffer \*buffer, int fenceFd, Region region) | Flushes the `NativeWindowBuffer` filled with the content to the buffer queue through a `NativeWindow` instance for content consumption.|
+| OH_NativeWindow_NativeWindowCancelBuffer (struct NativeWindow \*window, struct NativeWindowBuffer \*buffer) | Returns the `NativeWindowBuffer` to the buffer queue through a `NativeWindow` instance, without filling in any content. The `NativeWindowBuffer` can be used for another request.|
+| OH_NativeWindow_NativeWindowHandleOpt (struct NativeWindow \*window, int code,...) | Sets or obtains the attributes of a native window, including the width, height, and content format.|
+| OH_NativeWindow_GetBufferHandleFromNative (struct NativeWindowBuffer \*buffer) | Obtains the pointer to a `BufferHandle` of a `NativeWindowBuffer` instance.|
+| OH_NativeWindow_NativeObjectReference (void \*obj) | Adds the reference count of a native object.|
+| OH_NativeWindow_NativeObjectUnreference (void \*obj) | Decreases the reference count of a native object and, when the reference count reaches 0, destroys this object.|
+| OH_NativeWindow_GetNativeObjectMagic (void \*obj) | Obtains the magic ID of a native object.|
+## How to Develop
+The following steps describe how to use `OH_NativeXComponent` in OpenHarmony to draw content using native C++ code and display the content on the screen.
+1. Define an `XComponent` of the `texture` type in `index.ets` for content display.
+   ```js
+    XComponent({ id: 'xcomponentId', type: 'texture', libraryname: 'nativerender'})
+        .borderColor(Color.Red)
+        .borderWidth(5)
+        .onLoad(() => {})
+        .onDestroy(() => {})
+   ```
+2. Obtain an `OH_NativeXComponent` instance (named `nativeXComponent` in this example) by calling `napi_get_named_property`, and obtain a `NativeWindow` instance by registering the callback of the `OH_NativeXComponent` instance.
+    ```c++
+    // Define a NAPI instance.
+    napi_value exportInstance = nullptr;
+    // Define an OH_NativeXComponent instance.
+    OH_NativeXComponent *nativeXComponent = nullptr;
+    // Use the OH_NATIVE_XCOMPONENT_OBJ export instance.
+    napi_getname_property(env, exports, OH_NATIVE_XCOMPONENT_OBJ, &exportInstance);
+    // Convert the NAPI instance to the OH_NativeXComponent instance.
+    napi_unwarp(env, exportInstance, reinterpret_cast<void**>(&nativeXComponent));
+    ```
+3. Define the callback `OnSurfaceCreated`. During the creation of a `Surface`, the callback is used to initialize the rendering environment, for example, the `Skia` rendering environment, and write the content to be displayed to `NativeWindow`.
+    ```c++
+    void OnSurfaceCreatedCB(NativeXComponent* component, void* window) {
+        // Obtain the width and height of the native window.
+        uint64_t width_ = 0, height_ = 0;
+        OH_NativeXComponent_GetXComponentSize(nativeXComponent, window, &width_, &height_);
+        // Convert void* into a NativeWindow instance. NativeWindow is defined in native_window/external_window.h.
+        NativeWindow* nativeWindow_ = (NativeWindow*)(window);
+        // Set or obtain the NativeWindow attributes by calling OH_NativeWindow_NativeWindowHandleOpt.
+        // 1. Use SET_USAGE to set the usage attribute of the native window, for example, to HBM_USE_CPU_READ.
+        OH_NativeWindow_NativeWindowHandleOpt(nativeWindow_, SET_USAGE, HBM_USE_CPU_READ | HBM_USE_CPU_WRITE |HBM_USE_MEM_DMA);
+        // 2. Use SET_BUFFER_GEOMETRY to set the width and height attributes of the native window.
+        OH_NativeWindow_NativeWindowHandleOpt(nativeWindow_, SET_BUFFER_GEOMETRY, width_, height_);
+        // 3. Use SET_FORMAT to set the format attribute of the native window, for example, to PIXEL_FMT_RGBA_8888.
+        OH_NativeWindow_NativeWindowHandleOpt(nativeWindow_, SET_FORMAT, PIXEL_FMT_RGBA_8888);
+        // 4. Use SET_STRIDE to set the stride attribute of the native window.
+        OH_NativeWindow_NativeWindowHandleOpt(nativeWindow_, SET_STRIDE, 0x8);
+        // Obtain the NativeWindowBuffer instance by calling OH_NativeWindow_NativeWindowRequestBuffer.
+        struct NativeWindowBuffer* buffer = nullptr;
+        int fenceFd;
+        OH_NativeWindow_NativeWindowRequestBuffer(nativeWindow_, &buffer, &fenceFd);
+        // Obtain the buffer handle by calling OH_NativeWindow_GetNativeBufferHandleFromNative.
+        BufferHandle* bufferHandle = OH_NativeWindow_GetNativeBufferHandleFromNative(buffer);
+        // Create a Skia bitmap using BufferHandle.
+        SkBitmap bitmap;
+        SkImageInfo imageInfo = ...
+        bitmap.setInfo(imageInfo, bufferHandle->stride);
+        bitmap.setPixels(bufferHandle->virAddr);
+        // Create Skia Canvas and write the content to the native window.
+        ...
+        // After the write operation is complete, flush the buffer by using OH_NativeWindow_NativeWindowFlushBuffer so that the data is displayed on the screen.
+        Region region{nullptr, 0};
+        OH_NativeWindow_NativeWindowFlushBuffer(nativeWindow_, buffer, fenceFd, region)
+    }
+    ```
+4. Register the callback `OnSurfaceCreated` by using `OH_NativeXComponent_RegisterCallback`.
+    ```c++
+    OH_NativeXComponent_Callback &callback_;
+    callback_->OnSurfaceCreated = OnSurfaceCreatedCB;
+    callback_->OnSurfaceChanged = OnSurfaceChangedCB;
+    callback_->OnSurfaceDestoryed = OnSurfaceDestoryedCB;
+    callback_->DispatchTouchEvent = DispatchTouchEventCB;
+    OH_NativeXComponent_RegisterCallback(nativeXComponent, callback_)
+    ```
