Firebase Realtime Database is taking too much time for the first time connection

Here we are making an app using Firebase Relatime Database. When our app open for the first time it tries to connect to firebase database which takes a lot to time. And after that first connection it is really fast. I want to know how to establish the connection fast for the first time?

In this we can use SERVICE long running background task to solve first time slow connection ISSUE.

/**
 * Created by bipin on 1/18/17.
 */

public class FirstConnectionService extends Service {


    public static DatabaseReference databaseReference;
    private static String TAG = FirstConnectionService.class.getSimpleName();


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

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

        getDriverStatus();

        return START_STICKY;
    }


    /**
     *  long running background task using services
     */
    private void getDriverStatus() {

        try {

            databaseReference = FirebaseDatabase.getInstance().getReferenceFromUrl(
                    Constants.FIREBASE_DRIVER + "/" + 100 + "/status");
            databaseReference.addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot dataSnapshot) {

                    AppUtils.showLog(TAG, "onDataChange");

                }

                @Override
                public void onCancelled(DatabaseError databaseError) {

                    AppUtils.showLog(TAG, "onCancelled");

                }
            });

        } catch (Exception ex) {
            ex.printStackTrace();
        }

    }

}

And Start the service by checking if it is already running.

    /**
    * First check if service is already running.
    */
    if (!ServiceUtils.isMyServiceRunning(FirstConnectionService.class, this)) {

        AppUtils.showLog("FirstConnectionService", "isMyServiceRunning: false");
        startService(new Intent(this, FirstConnectionService.class));

    } else {

        AppUtils.showLog("FirstConnectionService", "isMyServiceRunning: true");

    }

Service Utils

/**
 * Created by bipin on 1/18/17.
 */

public class ServiceUtils {

    /**
     * Check if service is already running in background
     * */
    public static boolean isMyServiceRunning(Class<?> serviceClass, Context context) {

        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);

        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {

            if (serviceClass.getName().equals(service.service.getClassName())) {

                return true;

            }
        }
        return false;
    }

}
