Sending notifications from smartphone to Wear OS smartwatch

I've been trying to develop a simple app that can send notifications from a smartphone to an Wear OS smartwatch (more specifically, a Huawei Smartwatch 2).
I've used this code as a basis: github link. Note that this code doens't have the "notifications part" I'm trying to develop.
The bottom line is: I can receive data on the smartwatch, but only when the app on it is running. The ServiceListener service, from what I could tell, from debugging, is not being activated. Basically, anything I write on that file, even Log data, isn't being displayed.
The ServiceListener service:

Realm Database / App crashes in start up / call realm.init(context) before creating a realm configuration

I'm a newbie in Android and I'm trying to create a Realm database by watching tutorials. But my app doesn't start, it crashes. My main idea is the user finds nearby shops, by his location, select type of shop if he wants (restaurant, caffee etc) and if he can't find the shop he wants, the app gives him the option to add a shop (by pin a marker in a map, select a name and a type). In the errors gives me call realm.init(context) before creating a realm configuration Whoever can help I'd appreciate it. This app is my graduation project. I've reached this far;

Update your Manifest File.
Change tag android:name="Your.Pakage.Name.AppController"
"path.to.this.class.AppController"
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:name="Your.Pakage.Name.AppController"
android:theme="#style/AppTheme">
Update:
Now you are setting actionbar properties and getting issue.
To fix change Activity to AppCompatActivity
ListViewActivity extend AppCompatActivity

Sinch Service does not seem to start with Android Studio and Parse.com (Android Messaging Tutorial)

I am following this tutorial: https://www.sinch.com/tutorials/android-messaging-tutorial-using-sinch-and-parse
Github for tutorial: https://github.com/sinch/android-messaging-tutorial
The issue I have is that the service does not seem to start at all. I have gone over the code and cannot spot anything that looks wrong (but then again i'm a beginner lol).
I am not receiving any broadcast back in the MenuFragment3 class and due to that the progressDialog just keeps spinning. I have also checked to see if a service is running on both a number of emulators and a real device, like I said it seems as though the service never starts and I really cannot see why.
If you need anything more let me know and thanks for any help!
Firstly I start the service when a user logs in here:
serviceIntent = new Intent(getApplicationContext(), MessageService.class);
startService(serviceIntent);
Heres the manifest:

You're trying to initialize Parse using your Sinch key and secret. In addition, you should initialize Parse in your application's onCreate method. Try:
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
currentUserId = ParseUser.getCurrentUser().getObjectId();
if (currentUserId != null && !isSinchClientStarted()) {
startSinchClient(currentUserId);
}
broadcaster = LocalBroadcastManager.getInstance(this);
return super.onStartCommand(intent, flags, startId);
}

libGDX & Google Play Game Services "java.lang.RuntimeException: Unable to instantiate activity ComponentInfo"

Ok, so I'm trying to implement Google Play Games Services into my libGDX game. I followed the tutorial here: http://helios.hud.ac.uk/u1070589/blog/?p=202
When i run my game on my nexus, it force closes and logcat gives this Fatal Exception:
java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.ggtized.bb/com.ggtized.bb.MainActivity}: java.lang.ClassNotFoundException: Didn't find class "com.ggtized.bb.MainActivity" on path: DexPathList...
Without the implementation, my game works fine. But the tutorial seems to have been a success for many and i want GPGS too..
What is causing this error. I have no idea.. Can someone help and might tell me whats the problem? Thank you for your replies!!

And here's my Main Game Class
package com.ggtized.bb;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Game;
import com.ggtized.Screens.SplashScreen;
import com.ggtized.BHelpers.AssetLoader;
import com.ggtized.BHelpers.IReqHandler;
public class BGame extends Game implements ApplicationListener {
// Code for Ads
public static IReqHandler ExternalHandler;
// *****GPGS
private GoogleInterface platformInterface;
public BGame(IReqHandler irh, GoogleInterface aInterface) {
BGame.ExternalHandler = irh;
platformInterface = aInterface;
platformInterface.Login();
}
#Override
public void create() {
AssetLoader.load();
setScreen(new SplashScreen(this));
}
#Override
public void dispose() {
super.dispose();
AssetLoader.dispose();
}
}

I finally managed to find a way to solve the issue. In your BaseGameUtils Build Path--->Librairies, you normally have a android-support-v4.jar (or a similar .jar). Delete it from the Build Path (you already have it in the Build Path of your main app, seems to be conflicting in this case).
