I'm faced with almost the same problem FATAL EXCEPTION: Firebase-Messaging-Intent-Handle -- java.lang.NoClassDefFoundError. I was trying to update for the latest version of firebase analytics and messaging, and in one build it`s work for me. But after I removed some SDK(Facebook and Tenjin), and upload a new build this error show again. I try to remove all firebase, but the error still here, even when I don't use firebase.
On closed testing I am seeing crashes with this:
java.lang.NoClassDefFoundError: aewt
