如何使应用程序始终保持在后台，即使用户通过操作系统级别限制自行杀死/杀死

Question

由于我使用基于时间间隔的定位服务调用定位服务，但是当 onDestroy() 被调用时，所有服务都被停止，即使应用程序重新启动，位置也没有被获取并且警报管理器无法正常工作。

使用 GPS 位置提供程序。 使用 mqtt mosquitto 代理将位置发送到服务器。

public void onCreate() {
    super.onCreate();
    Log.i(TAG, "Inside onCreate() Method...............................");
    mLog.info(  "Inside onCreate() Method...............................");

    prefManager = new PrefManager(getApplicationContext());
    mqttParameters = MqttParams.getSetInstance();
    interval = GpsInterval.getSetInstance();
    Log.i(TAG, "mqttParameters : " + mqttParameters.toString());
    Log.i(TAG, "isPunchIn : " + isPunchIn);
    Log.i(TAG, "interval : " + interval);
    mLog.info(  "mqttParameters : " + mqttParameters.toString());
    mLog.info(  "isPunchIn : " + isPunchIn);
    mLog.info(  "interval : " + interval);
    try {
        if (Build.VERSION.SDK_INT >= 26) {

            String CHANNEL_ID = "my_service";
            String CHANNEL_NAME = "My Background Service";

            NotificationChannel channel = new NotificationChannel(CHANNEL_ID,
                    CHANNEL_NAME, NotificationManager.IMPORTANCE_NONE);
            ((NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE)).createNotificationChannel(channel);

            Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
                    .setCategory(Notification.CATEGORY_SERVICE).setPriority(PRIORITY_MIN).build();

            startForeground(101, notification);
        }
        // initialize();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
