Solution 1:

you need to use same version of firebasedependencies

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

or

compile'com.google.firebase:firebase-auth:9.6.1'compile'com.google.firebase:firebase-database:9.6.1'

Solution 2:

The problems of Multiple dex files define usually arise when you have duplicate dependency entry in your app build.gradle. In this case, you have a duplicate Firebase dependencies.

You need to use the same version either 9.0.2 or 9.6.1:

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

or

compile'com.google.firebase:firebase-auth:9.6.1'compile'com.google.firebase:firebase-database:9.6.1'

Please be aware that if you use some support library version like 24.0.0 there is a chance for compatibility issue with firebase. You need to use the latest of support library or find the compatible firebase version. Read more at android error while compiling com.android.support:support-v4:24.0.0
