 ### Starting a Page When the Target UIAbility Is Not Started for the First Time
 
-You start application A, and its home page is displayed. Then you return to the home screen and start application B. Now you need to start application A again from application B and access a specified page of application A. An example scenario is as follows: When you open the home page of the SMS application and return to the home screen, the SMS application is in the opened state with its home page. Then you open the home page of the Contacts application, access user A's details page, and touch the SMS icon to send an SMS message to user A. The SMS application is started again and the sending page is displayed.
+If the target UIAbility has been started, the initialization logic is not executed again. Instead, the **onNewWant()** lifecycle callback is directly triggered. To implement redirection, parse the required parameters in **onNewWant()**.
+
+An example scenario is as follows:
+
+1. A user opens the SMS application. The UIAbility instance of the SMS application is started, and the home page of the application is displayed.
+2. The user returns to the home screen, and the SMS application switches to the background.
+3. The user opens the Contacts application and finds a contact.
+4. The user touches the SMS button next to the contact. The UIAbility instance of the SMS application is restarted.
+5. Since the UIAbility instance of the SMS application has been started, the **onNewWant()** callback of the UIAbility is triggered, and the initialization logic such as **onCreate()** and **onWindowStageCreate()** is skipped.

+C-->>U: The page of the Contact app is displayed.

+The development procedure is as follows:
 
-In summary, when a UIAbility instance of application A has been created and the main page of the UIAbility instance is displayed, you need to start the UIAbility of application A from application B and access a different page.
+1. When the UIAbility instance of the SMS application is started for the first time, call [getUIContext()](../reference/apis/js-apis-window.md#getuicontext10) in the **onWindowStageCreate()** lifecycle callback to obtain the [UIContext](../reference/apis/js-apis-arkui-UIContext.md).
 
-1. In the target UIAbility, the **Index** page is loaded by default. The UIAbility instance has been created, and the **onNewWant()** callback rather than **onCreate()** and **onWindowStageCreate()** will be invoked. In the **onNewWant()** callback, parse the **want** parameter and bind it to the global variable **globalThis**.
-   
    ```ts
-   import UIAbility from '@ohos.app.ability.UIAbility'
+   import AbilityConstant from '@ohos.app.ability.AbilityConstant';
+   import UIAbility from '@ohos.app.ability.UIAbility';
+   import Want from '@ohos.app.ability.Want';
+   import window from '@ohos.window';
    
-   export default class FuncAbility extends UIAbility {
-     onNewWant(want, launchParam) {
-       // Receive the parameters passed by the initiator UIAbility.
-       globalThis.funcAbilityWant = want;
+   import { Router, UIContext } from '@ohos.arkui.UIContext';
+   
+   export default class EntryAbility extends UIAbility {
+     funcAbilityWant: Want;
+     uiContext: UIContext;
+   
+     ...
+     
+     onWindowStageCreate(windowStage: window.WindowStage) {
+       // Main window is created. Set a main page for this UIAbility.
        ...
+   
+       let windowClass: window.Window;
+       windowStage.getMainWindow((err, data) => {
+         if (err.code) {
+           console.error(`Failed to obtain the main window. Code is ${err.code}, message is ${err.message}`);
+           return;
+         }
+         windowClass = data;
+         this.uiContext = windowClass.getUIContext();
+       })
      }
    }
    ```
 
-2. In FuncAbility, use the router module to implement redirection to the specified page on the **Index** page. Because the **Index** page of FuncAbility is active, the variable will not be declared again and the **aboutToAppear()** callback will not be triggered. Therefore, the page routing functionality can be implemented in the **onPageShow()** callback of the **Index** page.
-   
+2. Parse the **want** parameter passed in the **onNewWant()** callback of the UIAbility of the SMS application, call [getRouter()](../reference/apis/js-apis-arkui-UIContext.md#getrouter) in the **UIContext** class to obtain a [Router](../reference/apis/js-apis-arkui-UIContext.md#router) instance, and specify the target page. When the UIAbility instance of the SMS application is started again, the specified page of the UIAbility instance of the SMS application is displayed.
+
    ```ts
-   import router from '@ohos.router';
-   
-   @Entry
-   @Component
-   struct Index {
-     onPageShow() {
-       let funcAbilityWant = globalThis.funcAbilityWant;
-       let url2 = funcAbilityWant?.parameters?.router;
-       if (url2 && url2 === 'funcA') {
-         router.replaceUrl({
-           url: 'pages/Second',
+   export default class EntryAbility extends UIAbility {
+     funcAbilityWant: Want;
+     uiContext: UIContext;
+   
+     onNewWant(want: Want, launchParams: AbilityConstant.LaunchParam) {
+       if (want?.parameters?.router && want.parameters.router === 'funcA') {
+         let funcAUrl = 'pages/Second';
+         let router: Router = this.uiContext.getRouter();
+         router.pushUrl({
+           url: funcAUrl
+         }).catch((err) => {
+           console.error(`Failed to push url. Code is ${err.code}, message is ${err.message}`);
          })
        }

 The **Want** object passed in by the widget host to the widget provider contains a flag that specifies whether the requested widget is normal or temporary.
 
-- Normal widget: a widget persistently used by the widget host
+- Normal widget: a widget persistently used by the widget host, for example, a widget added to the home screen.
 
-- Temporary widget: a widget temporarily used by the widget host
+- Temporary widget: a widget temporarily used by the widget host, for example, the widget displayed when you swipe up on a widget application.
+
+Converting a temporary widget to a normal one: After you swipe up on a widget application, a temporary widget is displayed. If you touch the pin button on the widget, it is displayed as a normal widget on the home screen.
 
 Data of a temporary widget will be deleted on the Widget Manager if the widget framework is killed and restarted. The widget provider, however, is not notified of the deletion and still keeps the data. Therefore, the widget provider needs to clear the data of temporary widgets proactively if the data has been kept for a long period of time. If the widget host has converted a temporary widget into a normal one, the widget provider should change the widget data from temporary storage to persistent storage. Otherwise, the widget data may be deleted by mistake.
