Failed to find byte code for com/google/firebase

I have the same error

Failed to find byte code for com/google/firebase/database/Transaction$Handler

(although i don't use firebase/database).

Have found that disabling instant run in AndroidStudio settings resolve this issue.

In the dependencies add:

compile 'com.google.firebase:firebase-database:11.8.0'
compile 'com.google.firebase:firebase-storage:11.8.0'

to be able to use ChildEventListener and StreamDownloadTask$StreamProcessor

Also you may have to write the other firebase dependencies

This is addressed in the latest react-native-firebase v4 release candidate, available here: https://github.com/invertase/react-native-firebase/releases/tag/v4.0.0-rc.3

The fix was ultimately to update the react-native-firebase build.gradle to use compileOnly instead of compile statements.
