Android: FCM java.io.IOException: SERVICE_NOT_AVAILABLE error on some devices

Question

I use FCM in my project

It work correct on Sony xperia, Galaxy S6, Motorola and more. But on Galaxy S3 i get java.io.IOException: SERVICE_NOT_AVAILABLE error

Time of Galaxy S3 is auto and google play is updated

Internet connection is strong and i connected to open internet without proxy

You may refer with this [thread](https://stackoverflow.com/questions/18325099/service-not-available-some-devices-on-android-gcm). This [error](https://developers.google.com/android/reference/com/google/android/gms/gcm/GoogleCloudMessaging#ERROR_SERVICE_NOT_AVAILABLE) means that your device can't read the response or there was a 500/503 from the server. You should use exponential back off and retry. — abielita, May 07 '18 at 14:11
@abielita My app is crashing with `Fatal Exception: com.google.android.gms.tasks.RuntimeExecutionException java.io.IOException: SERVICE_NOT_AVAILABLE` while try to retrieve the token from result. so my concern is how to prevent the app from crashing with this error? — Stella, Aug 08 '18 at 05:48
before accessing the result check for if(task!=null && task.isSuccessful())){ task.getResult()} this check will avoid app from getting crashed — Vijayalaxmi, Dec 11 '20 at 18:38

This error is caused when the device is unable to register to Firebase. Make sure the internet is working when this code is called. And put the code within try-catch to stop app from crashing.

Edit: Either add an internet connection check before registering the device or fetching token. Or wrap the Fetch token code in try-catch block to prevent app from crashing.

Also, in my case, the problem might be, when phone connected to Charles proxy. – Yuriy Dec 21 '21 at 12:25

Make sure that you have included

task.isSuccessful()

check in your code inside overriden onComplete method like this -

FirebaseMessaging.getInstance().getToken() .addOnCompleteListener(new OnCompleteListener() {

        @Override
        public void onComplete(@NonNull Task<String> task) {
            if(task.isSuccessful()) {
                fcmToken = task.getResult();
            }
        }
    });

If not, whenever a network error or some other issue occurs at the time of registration of fcm token, then you may get FIS_Authentication_Failed or SERVICE_NOT_AVAILABLE type of errors.

In my case problem was in Google Mobile Services app. After clearing its data problem disappeared.

I found a key for problem after launching on another device, where issue doesn't reproduces.
