How to setup Android application to use FCM?

Question

I've done the step by step in the tutorial, get json, adding dependecies (classpath 'com.google.gms:google-services:3.0.0'),
apply plugin (apply plugin: 'com.google.gms.google-services'), modify manifest file. (Don't forget to put these into application, not outside it!)

<service android:name=".MyFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>
<service android:name=".FirebaseIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

create firebaseMessagingService Class (MyFirebaseMessagingService.java)

public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "FCM Service";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // TODO: Handle FCM messages here.
    // If the application is in the foreground handle both data and notification messages here.
    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated.
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}
}

creating FirebaseIDService.java that extends FirebaseInstanceIdService

public class FirebaseIDService extends FirebaseInstanceIdService {
private static final String TAG = "FirebaseIDService";

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

/**
 * Persist token to third-party servers.
 *
 * Modify this method to associate the user's FCM InstanceID token with any server-side account
 * maintained by your application.
 *
 * @param token The new token.
 */
private void sendRegistrationToServer() {
    // Add custom implementation, as needed.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);
}
}

Here my main activity class snippet:

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    //FCM
    FirebaseIDService firebaseIDService = new FirebaseIDService();
    MyFirebaseMessagingService myFirebaseMessagingService = new MyFirebaseMessagingService();

Then I send the push notification from console, but nothing happens. What part is missing? or something is not working? I dunt get any logcat info from both class i create

UPDATE: this what i did to fix the Firebase not linked issue: I need to call the class manually and get token, and its working

FirebaseIDService firebaseIDService = new FirebaseIDService();
    firebaseIDService.getId();

But somehow, the push notification still not coming, the FCM class i used not giving any logcat, any idea?

UPDATE: so far i dunt find solution yet on receiving the message. the class that extends FirebaseMessagingService still not working, not showing anything in logcat, but it does showing something like this: D/FA: Logging event (FE): _nf, Bundle[{_o=fcm, _ndt=0, _nmn=Bayu testing PN, _nmt=1492745322, _nmid=2820998932030178856}]

No, it wont show that in logcat, my mainactivity class is correct,no ? i just need to create the class on mainactivity to run onTokenRefresh function, right? — Gabriel, Apr 20 '17 at 07:48
Remove your `FirebaseIDService firebaseIDService = new FirebaseIDService(); MyFirebaseMessagingService myFirebaseMessagingService = new MyFirebaseMessagingService();` lines from mainActivity because it willl automatically called.. — Rujul Gandhi, Apr 20 '17 at 07:49
i remove it, somehow i found this on logcat: D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization. Why is that? is this cause the error? — Gabriel, Apr 20 '17 at 07:57
The codes look okay. Are you positive that you're sending the message to the correct registration token? — AL., Apr 20 '17 at 08:45
i got the token, its very long string, like this: eKifiKFRQf8:APA91bGSwWpH5ziyM_HToeup_K98lZlbL0ivEedZZ-0g3wLnJlXt36yesY6yvWjlaS3mK3R6cZghE4a8dm5EwtY1BARo9t1Ctx4E0L0NMN-xXTi-vvskP1ll10mX0xLyDs7Jvw1kjCrT — Gabriel, Apr 20 '17 at 08:50

I have it working now, the issue is because i put service outside of the application, so the services must inside the application, so the onReceivedMessage will work

Please consider updating the question with the portion of the wrong manifest, and explain in the answer what was the error. So a future reader can learn from this question. – Diego Giorgini Apr 22 '17 at 00:59

You probably skipped this step, since i don't see you mentioned it:
In your module Gradle file (usually the app/build.gradle), add the apply plugin line at the bottom of the file to enable the Gradle plugin:

apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  compile 'com.google.firebase:firebase-core:10.2.1'

  // Getting a "Could not find" error? Make sure you have
  // the latest Google Repository in the Android SDK manager
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

Please note the: compile 'com.google.firebase:firebase-core:10.2.1'
