crash闪退时能保存状态并重新恢复启动

import appRecovery from '@ohos.app.ability.appRecovery'; 
import AbilityStage from '@ohos.app.ability.AbilityStage'; 
import Want from '@ohos.app.ability.Want'; 
 
export default class MyAbilityStage extends AbilityStage { 
  onCreate() { 
    console.log('fyh:MyAbilityStage,onCreate'); 
    appRecovery.enableAppRecovery( 
      appRecovery.RestartFlag.ALWAYS_RESTART, 
      appRecovery.SaveOccasionFlag.SAVE_WHEN_ERROR, 
      appRecovery.SaveModeFlag.SAVE_WITH_FILE 
    ); 
    let want: Want = { 
      bundleName: 'com.example.binfo', 
      abilityName: "EntryAbility" 
    }; 
    //恢复应用设置启动want 
    appRecovery.setRestartWant(want); 
  } 
}
