-
-
-## Usage
-
-
-Before using the **AbilityContext** module, you must define a child class that inherits from **Ability**.
-
-
-  
-```js
-import Ability from '@ohos.application.Ability'
-class MainAbility extends Ability {
-    onWindowStageCreate(windowStage) {
-        let context = this.context;
-    }
-}
-```
