如何通过代码触发APP重启

1.创建Ability 
//AbilityStage 
import appRecovery from ‘@ohos.app.ability.appRecovery’; 
import AbilityStage from ‘@ohos.app.ability.AbilityStage’; 
export default class MyAbilityStage extends AbilityStage { 
  onCreate() { 
    appRecovery.enableAppRecovery( 
      appRecovery.RestartFlag.ALWAYS_RESTART, 
      appRecovery.SaveOccasionFlag.SAVE_WHEN_ERROR, 
      appRecovery.SaveModeFlag.SAVE_WITH_FILE 
    ); 
 
    let want ={ 
      bundleName:‘com.example.test’, 
      abilityName:“EntryAbility” 
    } 
    appRecovery.setRestartWant(want) 
  } 
} 
 
2.配置Ability作为启动ability 
“module”: { 
“name”: “entry”, 
“srcEntry”: ‘./ets/AbilityStage/AbilityStage.ets’, 
… 
3.设置需要重启的UIAiblity 
“abilities”: [ 
{ 
“name”: “EntryAbility”, 
… 
“recoverable”: true, 
… 
4.页面执行重启APP的操作 
//page 
.onClick(() => { 
appRecovery.restartApp(); 
})
