如何主动关闭应用

Answer 1

可以使用UIAbilityContext.terminateSelf方法停止Ability。参考如下示例：

import UIAbility from '@ohos.app.ability.UIAbility'; 
import { BusinessError } from '@ohos.base'; 
 
export default class EntryAbility extends UIAbility { 
  onForeground() { 
    try { 
      this.context.terminateSelf((err: BusinessError) => { 
        if (err.code) { 
          // 处理业务逻辑错误 
          console.error(`terminateSelf failed, code is ${err.code}, message is ${err.message}`); 
          return; 
        } 
        // 执行正常业务 
        console.info('terminateSelf succeed'); 
      }); 
    } catch (err) { 
      // 捕获同步的参数错误 
      let code = (err as BusinessError).code; 
      let message = (err as BusinessError).message; 
      console.error(`terminateSelf failed, code is ${code}, message is ${message}`); 
    } 
  } 
}
