+# Setting the Icon and Name of a Mission Snapshot
+
+Setting a unique icon and name for each mission snapshot of an application helps you better manage the missions and functions of the application.
+
+By default, the **icon** and **label** fields in the [abilities tag](../quick-start/module-configuration-file.md#abilities) of the [module.json5 file](../quick-start/module-configuration-file.md) are used to set the icon and label.
+
+Figure 1 Mission snapshot of a UIAbility
+
+![](figures/mission-list-recent.png)
+
+You can also use [UIAbilityContext.setMissionIcon()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissionicon) and [UIAbilityContext.setMissionLabel()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissionlabel) to customize the icon and name for a mission snapshot. For example, for a UIAbility instance in multiton mode, you can configure the icon and name for each mission snapshot based on different functions.
+
+This document describes the following operations:

+## Setting a Mission Snapshot Icon (for System Applications Only)
+
+Call [UIAbilityContext.setMissionIcon()](../reference/apis/js-apis-inner-application-uiAbilityContext.md#uiabilitycontextsetmissionicon) to set the icon of a mission snapshot. The icon is an object of the [PixelMap](../reference/apis/js-apis-image.md#pixelmap7) type. For details about how to obtain the context, see [Obtaining the Context of UIAbility](uiability-usage.md#obtaining-the-context-of-uiability).

+# Subscribing to System Environment Variable Changes
+
+System environment variables are system settings (for example, the system language or screen direction) of a device that may change during the running of an application.
+
+By subscribing to the changes of system environment variables, the application can detect the changes in a timely manner and process the changes accordingly, providing better user experience. For example, when the system language changes, the application can display the UI in the new language; when the user rotates the device to landscape or portrait mode, the application can re-arrange the UI to adapt to the new screen orientation and size.
+
+The system environment variable changes are usually triggered by options in **Settings** or icons in **Control Panel**. For details about the system environment variables that support subscription, see [Configuration](../reference/apis/js-apis-app-ability-configuration.md).
+
+In OpenHarmony, you can subscribe to system environment variable changes in the following ways:
+
+- [Using ApplicationContext for Subscription](#using-applicationcontext-for-subscription)
+- [Using AbilityStage for Subscription](#using-abilitystage-for-subscription)
+- [Using UIAbility for Subscription](#using-uiability-for-subscription)
+- [Using ExtensionAbility for Subscription](#using-extensionability-for-subscription)
+
+## Using ApplicationContext for Subscription
+
+[ApplicationContext](../reference/apis/js-apis-inner-application-applicationContext.md) provides an API for registering a callback function to subscribe to the system environment variable changes. It also provides an API for deregistration so you can release related resources when they are no longer needed.
+
+1. Call **ApplicationContext.on(type: 'environment', callback: EnvironmentCallback)** to subscribe to changes in system environment variables. The code snippet below is used to subscribe to system language changes on a page.
+
+   ```ts
+   import common from '@ohos.app.ability.common';
+   
+   @Entry
+   @Component
+   struct Index {
+     private context = getContext(this) as common.UIAbilityContext;
+     private callbackId: number; // ID of the subscription for system environment variable changes.
+   
+     subscribeConfigurationUpdate() {
+       let systemLanguage: string = this.context.config.language; // Obtain the system language in use.
+   
+       // 1. Obtain an ApplicationContext object.
+       let applicationContext = this.context.getApplicationContext();
+   
+       // 2. Subscribe to system environment variable changes through ApplicationContext.
+       let environmentCallback = {
+         onConfigurationUpdated(newConfig) {
+           console.info(`onConfigurationUpdated systemLanguage is ${systemLanguage}, newConfig: ${JSON.stringify(newConfig)}`);
+   
+           if (this.systemLanguage !== newConfig.language) {
+             console.info(`systemLanguage from ${systemLanguage} changed to ${newConfig.language}`);
+             systemLanguage = newConfig.language; // Save the new system language as the system language in use, which will be used for comparison.
+           }
+         },
+         onMemoryLevel(level) {
+           console.info(`onMemoryLevel level: ${level}`);
+         }
+       }
+   
+       this.callbackId = applicationContext.on('environment', environmentCallback);
+     }
+   
+     // Page display.
+     build() {
+       // ...
+     }
+   }
+   ```
+
+2. Call **ApplicationContext.off(type: 'environment', callbackId: number)** to release the resources.
+
+   ```ts
+   import common from '@ohos.app.ability.common';
+   
+   @Entry
+   @Component
+   struct Index {
+     private context = getContext(this) as common.UIAbilityContext;
+     private callbackId: number; // ID of the subscription for system environment variable changes.
+   
+     unsubscribeConfigurationUpdate() {
+       let applicationContext = this.context.getApplicationContext();
+       applicationContext.off('environment', this.callbackId);
+     }
+   
+     // Page display.
+     build() {
+       // ...
+     }
+   }
+   ```
+
+## Using AbilityStage for Subscription
+
+The AbilityStage component provides the [AbilityStage.onConfigurationUpdate()](../reference/apis/js-apis-app-ability-abilityStage.md#abilitystageonconfigurationupdate) callback for subscribing to system environment variable changes. This callback is invoked when a system environment variable changes. In this callback, the latest system environment configuration is obtained through the [Configuration](../reference/apis/js-apis-app-ability-configuration.md) object.  
+
+> **NOTE**
+>
+> - AbilityStage is not automatically generated in the default project of DevEco Studio. For details about how to create an AbilityStage file, see [AbilityStage Component Container](abilitystage.md).
+> - The callback used to subscribe to system environment variable changes has the same lifecycle as the [AbilityStage](../reference/apis/js-apis-app-ability-abilityStage.md) instance and will be destroyed when the instance is destroyed.
+
+The code snippet below uses the [AbilityStage.onConfigurationUpdate()](../reference/apis/js-apis-app-ability-abilityStage.md#abilitystageonconfigurationupdate) callback to subscribe to the system language changes.
+
+```ts
+import AbilityStage from '@ohos.app.ability.AbilityStage';
+
+let systemLanguage: string; // System language in use.
+
+export default class MyAbilityStage extends AbilityStage {
+    onCreate() {
+        systemLanguage = this.context.config.language; // Obtain the system language in use when the AbilityStage instance is loaded for the first time.
+        console.info(`systemLanguage is ${systemLanguage} `);
+    }
+
+    onConfigurationUpdate(newConfig) {
+        console.info(`onConfigurationUpdated systemLanguage is ${systemLanguage}, newConfig: ${JSON.stringify(newConfig)}`);

+
+## Using UIAbility for Subscription
+
+The UIAbility component provides the **UIAbility.onConfigurationUpdate()** callback for subscribing to system environment variable changes. This callback is invoked when a system environment variable changes. In this callback, the latest system environment configuration is obtained through the [Configuration](../reference/apis/js-apis-app-ability-configuration.md) object, without restarting the UIAbility.
+
+> **NOTE**
+>
+> The callback used to subscribe to system environment variable changes has the same lifecycle as the UIAbility instance and will be destroyed when the instance is destroyed.
+
+The code snippet below uses the **onConfigurationUpdate()** callback to subscribe to the system language changes.
+
+```ts
+import UIAbility from '@ohos.app.ability.UIAbility';
+
+let systemLanguage: string; // System language in use.
+
+export default class EntryAbility extends UIAbility {
+    onCreate(want, launchParam) {
+        systemLanguage = this.context.config.language; // Obtain the system language in use when the UIAbility instance is loaded for the first time.
+        console.info(`systemLanguage is ${systemLanguage} `);
+    }
+
+    onConfigurationUpdate(newConfig) {
+        console.info(`onConfigurationUpdated systemLanguage is ${systemLanguage}, newConfig: ${JSON.stringify(newConfig)}`);
+
+        if (systemLanguage !== newConfig.language) {

+## Using ExtensionAbility for Subscription
+
+The ExtensionAbility component provides the **onConfigurationUpdate()** callback for subscribing system environment variable changes. This callback is invoked when a system environment variable changes. In this callback, the latest system environment configuration is obtained through the [Configuration](../reference/apis/js-apis-app-ability-configuration.md) object.
+
+> **NOTE**
+>
+> The callback used to subscribe to system environment variable changes has the same lifecycle as the ExtensionAbility instance and will be destroyed when the instance is destroyed.

 ### 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)
+- AppScope (only for 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.)

+## AccessibilityExtensionAbility概述
+
+“信息无障碍”译自“Accessibility”，是指任何人在任何情况下都能平等、方便地获取信息并利用信息。其目的是缩小全社会不同阶层、不同地区、不同年龄、不同健康状况的人群在信息理解、信息交互、信息利用方面的数字鸿沟，使其更加方便地参与社会生活，享受数字发展带来的便利。
+
+AccessibilityExtensionAbility为无障碍扩展服务框架，允许三方开发自己的扩展服务，提供在应用程序和扩展服务之间交换信息的标准机制，以便为各种障碍人群和障碍场景提供辅助能力，增强用户的无障碍使用体验。例如在使用微信时，利用辅助应用旁白，用户可以“听见”当前屏幕内容。
+
+![AccessibilityFramework](figures/AccessibilityFramework.png)
+
+1. Accessibility App：开发者基于无障碍扩展服务框架扩展出来的扩展服务应用，如视障用户使用的读屏App。
+2. Tartget App：被Accessibility App辅助的目标应用。
+3. AccessibilityAbilityManagerService（AAMS）：无障碍扩展服务框架主服务，用于对Accessibility App生命周期进行管理，同时为Accessibility App和Target App提供信息交互的桥梁。
+4. AccessibilityAbility（AAkit）：Accessibility App利用AAkit构建扩展服务Ability运行环境，并为Accessibility App提供可查询和操作Target App的接口，如查询节点信息、对节点执行点击/长按操作等。
+5. AccessibilitySystemAbilityClient（ASACkit）：Target App通过ASACkit向AAMS发送无障碍事件，如内容变化事件等，同时响应Accessibility App通过AAMS请求的指令，如查询节点信息、对节点执行点击/长按操作等。
+
 ## 如何创建一个无障碍扩展服务
 
 开发者在创建一个无障碍扩展服务时，如工程满足环境要求，开发者可自主选择是否跳过创建工程步骤，在已有工程中新增无障碍扩展服务。
