Why the Service still ( Seem to Be )alive after I call stopService

Question

I have a Service of My App,and I use it for Socket.IO. I don't want to allow binding,so:

/**
 * You must always implement this method, but if you don't want to allow binding
 * then you should return null.
 */
@Override
public IBinder onBind(@NonNull Intent intent) {
    return null;
}


@Override
public int onStartCommand(@NonNull Intent intent, int flags, int startId) {
    return START_NOT_STICKY;
}

And I init the Socket.IO in the onCreate():

@Override
public void onCreate() {
    super.onCreate();
    mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    Log.d(TAG, "Service Create");
    //...More
    setForeground();
    initSocketIO();
}


private void setForeground() {
    Intent notificationIntent = new Intent(this, LiveTabActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    //getNotification() is deprecated in API16
    if (Build.VERSION.SDK_INT >= 16) {
        Notification notification = new Notification.Builder(context)
                .setContentTitle(getString(R.string.app_name))
                .setContentText(getString(R.string.service_running))
                .setSmallIcon(R.drawable.defimgs)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.md1))
                .setContentIntent(pendingIntent).build();
        startForeground(100, notification);
        return;
    }
    Notification notification = new Notification.Builder(context)
            .setContentTitle(getString(R.string.app_name))
            .setContentText(getString(R.string.service_running))
            .setSmallIcon(R.drawable.defimgs)
            .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.md1))
            .setContentIntent(pendingIntent).getNotification();
    startForeground(100, notification);
}

@Override
public void onDestroy() {
    super.onDestroy();
    Log.d(TAG, "Service onDestroy");
    //...more
}

In initSocketIO() I init the data of Socket.IO so that I can receive the Message of the server.And when the Service receive the message ,It will have a Log and push a Notification.

After that the app work well.But in this App I want to provide the function for user to logout their account.So when user select to logout this App should stop the Service.

But when I use stopService() in the Activity to stop the Service, I can see the "Service onDestroy" in the LogCat but the Service is still alive! Because I can see the Log in LogCat when the Service receive message from Server!

Even if I use EventBus to send a Event to this Service to make this Service call stopSelf by itself , this problem remains.

So How can I stop the Service which start with Foreground ? Thanks for your help.

You do not show it in your code, but it sounds like you still have an active listener for socketIO. In onDestroy, you need to call off and disconnect on the Socket you previously created in initSocketIO. Also, if you started any background threads yourself in the service, you need to make sure they are shutdown in onDestroy.

Service is destroyed , but the listener of Socket.IO is still alive . Remember to close Socket.IO and shutdown the background thread.
