Location tracking on Oreo and later by using an IntentService

Question

I am working on a location tracking application. I need to fetch the user location on every 500-meter displacement or in every 30 minutes. I created a foreground service and returned START_STICKY on onStartCommand method. Tracking is working perfectly until the app is cleared from recent apps. If I cleared my app from recent apps section the foreground service also removing from the background. how can I make it sticky there forever?

Note: I am doing this location tracking with the knowledge of user .

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Temp.msg(TAG, "onStartCommand");

    startMyOwnForeground();
    return START_STICKY;
} 


private void startMyOwnForeground() {
    String NOTIFICATION_CHANNEL_ID = Temp.getNotificationChannelId();
    String channelName = Temp.getNotificationChannelName();
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        NotificationChannel chan = null;
        chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_NONE);

        chan.setLightColor(Color.BLUE);
        chan.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        assert manager != null;
        manager.createNotificationChannel(chan);
    }
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
    Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.drawable.ic_push_notifications)
            .setContentTitle("Checked In")
            .setPriority(NotificationManager.IMPORTANCE_HIGH)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build();
    startForeground(1, notification);
}

Note: I tried START_STICKY and START_NOT_STICKY on onStartCommand method but it both removed from the background when the app removed from recent apps

Answer 1

I found why the app is removing from the background. That was not my code's problem. It happened because the phone I used was Redmi. In Redmi phones, It requires additional permission (AutoStart permission) from Redmi phone settings. You can get more info about this from Foreground service getting killed from Oreo
