java.io.IOException: AUTHENTICATION_FAILED in Android Firebase (and SERVICE_NOT_AVAILABLE)

Question

I'm getting following error on some devices while fetching firebase token:

Fatal Exception: d.b.a.b.g.f
java.io.IOException: AUTHENTICATION_FAILED

Here is the code which is responsible to fetch firebase token:

FirebaseInstanceId.getInstance().getInstanceId().addOnCompleteListener(new OnCompleteListener<InstanceIdResult>() {
            @Override
            public void onComplete(@NonNull Task<InstanceIdResult> task) {
                if (task.getResult() != null && task.isSuccessful()) {
                    String firebaseToken = task.getResult().getToken();
                }
            }
        });

I'm using following gradle dependencies.

implementation 'com.google.firebase:firebase-analytics:17.4.3'
implementation 'com.google.firebase:firebase-crashlytics:17.0.1'
implementation 'com.google.firebase:firebase-messaging:20.2.0'

I found similar questions and problems but no conclusive answer. Some suggest it may be result of broken internet connection but my app needs authenticate before entering the app so internet is available. Is there anybody encountered same issue? Best regards.

I experienced this issue, so factory reset the device and it works now. Sadly I do not know what caused it. – Cockswain

How will you factory reset a user's device? @HungryArthur. What if your app users are getting this error? – Itagaki

I should have pointed out these were on internal devices that we had control over. – Cockswain

If this happens on Android Emulator, do a Wipe Data from AVD on that specific instance and then start it. – Aperient

@ŠemsudinTafilović - this worked haven't tested on real device thanks. – Topo

Answer 1

implementation platform('com.google.firebase:firebase-bom:26.4.0')
implementation "com.google.firebase:firebase-messaging"

The bomb has been planted (c) Google... And it is still there...
Ended up with the following code:

    try {
        FirebaseMessaging.getInstance().getToken().addOnCompleteListener(task -> {
            if (task.isSuccessful()) {
                final String token = task.getResult();
                //GOT the token!
            }
        });
    } catch (Exception e) {
        // OMG, Firebase is used to log Firebase crash :)
        // I'm not sure if this will work...
        FirebaseCrashlytics.getInstance().recordException(e);
        gotFBCrash = true;
    }
    if (gotFBCrash) {
        FirebaseInstanceId.getInstance().getInstanceId().addOnCompleteListener(task -> {
            if (task.isSuccessful()) {
                final String token = task.getResult().getToken();
                //GOT the token!
            }
        });
    }

Actually the second part is two times deprecated code (thats why I'm here - updating to actual code results in app crash) but it works. You can use only the second way to obtain FCM token if you wish and hate try/catch

Answer 2

It's bug on Firebase side, more and more users are affected by this issue:

Here the issue on Google issue tracker:

• https://issuetracker.google.com/issues/143413382

And here the issue on Firebase issue tracker:

• https://github.com/firebase/firebase-android-sdk/issues/1286

If you can get more information from your users to help Google developers fixing this issue, it could help =)

Answer 3

in my case, non of above solved my issue, I get token from service callback and do with it whatever I need

public class LatestFirebaseMessagingService extends FirebaseMessagingService {

@Override
public void onNewToken(String mToken) {
    super.onNewToken(mToken);
    Log.e("TOKEN",mToken);
}

Answer 4

It's been two years since the question's been posted, BUT the exception still exists on some devices / emulators. One of the reasons is unavailable/disabled Google Play app/services (I've just encountered this exception today).

Google Play services is required to create a token and it will fail on devices without it.

In production users probably downloaded the app via Google Play, so play services are enabled – Asur

Answer 5

Try Sign in into google account in android studio using top right sign in icon. This works for me.

Reckoner

This what worked for me, Thank you – Underproduction

Answer 6

One of the reasons might be that multiple emulators are running. Leaving only one emulator solved the issue for me.
