I recently updated Android Studio to version 2.2.2 and have been experiencing some issues, among them my application name is no longer being recognized in the manifest. I also migrated to the new Firebase SDK based on the documentation located here:
I am not exactly sure of the cause, but have been reading about multidexing as being one of the components related to this error. I am also receiving a run-time error below that I believe also relates to the issue:

Any help or advice is appreciated!
As you don't have a class com.troychuinard.fanpolls.FanPollsApplication, just remove the attribute name='.FanPollsApplication'. It will use standard android.app.Application instead.
I think when you add firebase, you application is over 64k methods and you need to follow this link about MultiDex
