Answer 1

seems, i found the answer. It helps me!

I have used before android studio version 1.5 And that's why (maybe not) but i could't upgrade required firebase libs to 9.0.2 All this time i have used 9.0.0

So firstly i upgrade my android studio to updated stable version 2.2 and then update version of dependencies to next ones:

compile 'com.google.firebase:firebase-core:9.0.2'
compile 'com.google.firebase:firebase-auth:9.0.2'
compile 'com.google.firebase:firebase-database:9.0.2'

And now all values are saved to database from android app.

So do two things: 1. update android studio to last stable version 2. update firebase required libs versions

Hope this answer will help
