`Please correct the above warnings first.` what does your warnings tell you? — nenick, Sep 22 '16 at 05:31
`compile 'com.facebook.android:facebook-android-sdk:[4,5)'`, is this a typo? — ישו אוהב אותך, Sep 22 '16 at 06:02

When using Firebase Authentication with compile 'com.google.firebase:firebase-auth:9.2.1' try adding the following flags to your proguard-rules.pro:

-keepattributes Signature
-keepattributes *Annotation*

Read more at Set up Firebase Authentication for Android.

For Firebase Realtime Database with compile 'com.google.firebase:firebase-database:9.2.1' you need to consider how your model objects will be serialized and deserialized after obfuscation. For details, read more at Set up Firebase Realtime Database for Android.
