Android Question Firebase null pointer exception

[mc73]

Following the firebase push notifications' tutorial, I end up with the following error:

firebasemessaging_subscribetotopics (java line: 228)
java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.firebase.iid.FirebaseInstanceId.zza(java.lang.String)' on a null object reference

I attach the test project zipped. Any help would be appreciated, thank you.

Has the last release of firebaseanalytics anything to do with Firebase messaging? I'm using the old library and it works very well for Messaging

With the updated sdk components you need to have this new version. But just for the macros included i think
