Overriding onNewToken and getting tokens from firebase errors

Question

I want to retrieve my token and i'm doing exactly as many examples says On FirebaseMessagingService i have this

 @Override
    public void onNewToken(String token) {
        super.onNewToken(token);
        Log.e("Refreshed token:",token);
    }

And i got the error

Method does not override method from it's superclass

and of course the super.onNewToken(token) has the error

cannot resolve method

On my mainactivity i have this inside OnCreate()

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener<InstanceIdResult>() {
     @Override
     public void onSuccess(InstanceIdResult instanceIdResult) {          
           String newToken = instanceIdResult.getToken();    
     }
 });

And the errors i get are:

Cannot resolve getInstanceId()

Cannot resolve InstanceIdResult

cannot resolve getToken()

and Method does not override method from it's

superclass

Update

Class declaration

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static final String TAG = MyFirebaseMessagingService.class.getSimpleName();

    private NotificationUtils notificationUtils;


    @Override
    public void onNewToken(String token) {
        super.onNewToken(token);
        Log.e("Refreshed token:",token);
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.e(TAG, "From: " + remoteMessage.getFrom());

        if (remoteMessage == null)
            return;

        // Check if message contains a notification payload.
        if (remoteMessage.getNotification() != null) {
            Log.e(TAG, "Notification Body: " + remoteMessage.getNotification().getBody());
            handleNotification(remoteMessage.getNotification().getBody());
        }

        // Check if message contains a data payload.
        if (remoteMessage.getData().size() > 0) {
            Log.e(TAG, "Data Payload: " + remoteMessage.getData().toString());

            try {
                JSONObject json = new JSONObject(remoteMessage.getData().toString());
                handleDataMessage(json);
            } catch (Exception e) {
                Log.e(TAG, "Exception: " + e.getMessage());
            }
        }
    }

Make sure you are using latest `dependencies` of `implementation 'com.google.firebase:firebase-messaging:17.3.4` https://firebase.google.com/docs/cloud-messaging/android/client — AskNilesh, Dec 03 '18 at 10:43
show the class declaration, where you wrote `class yourclass extends FirebaseMessagingService` — Vladyslav Matviienko, Dec 03 '18 at 10:44
looks weird. Can you also show the dependancies? (the firebase one at least) — Vladyslav Matviienko, Dec 03 '18 at 10:50
@VladyslavMatviienko check the dependancies!I know it's weird!!! — Alex, Dec 03 '18 at 10:51
can you check inside the `FirebaseMessagingService` class what is the signature of `onNewToken` method? CTRL+Click on the `FirebaseMessagingService` in your code to open it — Vladyslav Matviienko, Dec 03 '18 at 10:54
@VladyslavMatviienko when i press ctrl-click it says no usages found in all places — Alex, Dec 03 '18 at 10:56
oh, if you are using a MacOS, then it should be command + click — Vladyslav Matviienko, Dec 03 '18 at 10:56
`CTRL+Click on the FirebaseMessagingService`, not on the `onNewToken` — Vladyslav Matviienko, Dec 03 '18 at 11:02
@AlexKolydas you code is working fine for me have u tried **`Clean-ReBuild`** or `Invalidate-cache and restart android studio` — AskNilesh, Dec 03 '18 at 11:02
@VladyslavMatviienko sorry i'm stupid :P check the second update — Alex, Dec 03 '18 at 11:05
as you see, this class is really missing the `onNewToken` method. I have no idea why unfortunately. I'd suggest you to re-download the dependencies. — Vladyslav Matviienko, Dec 03 '18 at 11:13
@VladyslavMatviienko thank you very much for your time!i will see what i can do! — Alex, Dec 03 '18 at 11:21
I have the same problem, can you tell me how you resolved it please? — Haya Akkad, Jun 17 '19 at 01:55

build.gradle (app):

implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-messaging:17.3.4'

extend class:

package /*package name*/;

import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;

public class MyFcmListenerService extends FirebaseMessagingService {
    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is also called
     * when the Instance ID token is initially generated, so this is where
     * you retrieve the token.
     */
    @Override
    public void onNewToken(String token) {
        Log.d("TAG", "New token: " + token);
        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(token); //As I understand it, you need to implement it yourself.
    }
}

in tag in AndroidManifest.xml:

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

Add to your activity where you want to get a token:

FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(MainActivity.this,  new OnSuccessListener<InstanceIdResult>() {
       @Override
       public void onSuccess(InstanceIdResult instanceIdResult) {
           String newToken = instanceIdResult.getToken();
       }
    });

There is an error with `getApplication ()` for the code below. Do you know how to handle it? `private void sendRegistrationToServer(@Nullable String token) { if (token != null) { ((SubApp) getApplication()).getRepository().registerInstanceId(token); // No need to unregister the previous Instance ID token because the server // automatically removes invalidated tokens. } }` — Namikaze Minato, May 03 '20 at 03:50
And still: `Method doesn't override method from its superclass`. I am working on classytaxijava that I get these errors — Namikaze Minato, May 03 '20 at 03:53
