NullPointerException on FirebaseMessagingService.zzo(Unknown Source)

Does anyone knows about this crash?

Fatal Exception: java.lang.NullPointerException
       at com.google.firebase.messaging.FirebaseMessagingService.zzo(Unknown Source)
       at com.google.firebase.messaging.FirebaseMessagingService.zzn(Unknown Source)
       at com.google.firebase.messaging.FirebaseMessagingService.zzm(Unknown Source)
       at com.google.firebase.iid.zzb$2.run(Unknown Source)
       at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076)
       at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569)
       at java.lang.Thread.run(Thread.java:856)

It doesn't happen that much, about 0.1% of sessions.

Reported environments: GI-I9500_TMMARS / Android 4.1.1.

String name;

In order to fix this error you should update firebase in your Gradle file and add the 2nd line: 

compile 'com.google.firebase:firebase-messaging:10.0.1' 
compile 'com.google.firebase:firebase-core:10.0.1' // also need to add this line.

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

Don't forget to update the Gradle file in the root folder of your project as well otherwise you won't be able to get the version 10.0.1:

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

This problem is discussed as an issue for the Quick Start project. Comments there from the Firebase support team indicate the problem is fixed in SDK version 9.4.0. Are you building with that version?
