用户或系统杀死它时以编程方式重新启动服务

Question

我有一个后台服务，即使我的主要活动被杀或处于后台，也会运行很长时间。

问题出在：

1. 用户从设置手动杀死服务---＆gt; app ---＆gt; myapp 强制停止
2. 功耗密集型模式（例如华为的超级模式）处于活动状态

在这种情况下，我的服务被终止，无法自动重启。

这是我的服务代码：

public class MyService extends Service {

  protected final String TAG = this.getClass().getName();

  @Override
  public void onCreate() {
    super.onCreate();
  }

  @Override
  public final int onStartCommand(Intent intent, int flags, int startId) {

      Log.i(TAG, "onStarCommand(): Received id " + startId + ": " + intent);
      return START_STICKY;

  }

  @Override
  public final IBinder onBind(Intent intent) {
    return m_messenger.getBinder();
  }

  @Override
  public void onDestroy() {
    super.onDestroy();
    Log.i(TAG, "Service Stopped.");
  }    

  @Override
  public void onTaskRemoved(Intent rootIntent){
    Intent restartServiceTask = new Intent(getApplicationContext(),this.getClass());
    restartServiceTask.setPackage(getPackageName());    
    PendingIntent restartPendingIntent =PendingIntent.getService(getApplicationContext(), 1,restartServiceTask, PendingIntent.FLAG_ONE_SHOT);
    AlarmManager myAlarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    myAlarmService.set(
        AlarmManager.ELAPSED_REALTIME,
        SystemClock.elapsedRealtime() + 1000,
        restartPendingIntent);

    super.onTaskRemoved(rootIntent);
  }
}
