不从警报接收器启动服务

Question

我是android的新手。我的目标是在特定时间启动服务。上面的代码没有显示出良好的效果。

闹钟接收器：

public class AlarmReceiverActivity extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    Intent background = new Intent(context, BackgroundService.class);
    context.startService(background);
}}

服务类：

@TargetApi(Build.VERSION_CODES.N)
public class BackgroundService extends Service {
private boolean isRunning  = false;
private Context context;
private Thread backgroundThread;






@Override
public IBinder onBind(Intent intent) {
    return null;
}



private Runnable myTask = new Runnable() {
    public void run() {

        //task

        stopSelf();
    }
};

@Override
public void onCreate() {
    this.context = this;
    this.isRunning = true;
    this.backgroundThread= new Thread(myTask);
    }






@Override
public void onDestroy() {
    this.isRunning = false;
    stored3();

}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    //if(!this.isRunning) {
        //this.isRunning = true;
        this.backgroundThread= new Thread(myTask);
        this.backgroundThread.start();
        stored4();
    //}

    return START_STICKY;
}}

Oncreate方法不是由系统执行的，所以我猜问题来自报警接收器。代码有问题吗？我会感激任何帮助。
