I have followed Firebase quick start guide to complete initial setup of Firebase. I haven't used any of it's classes yet , just done basic setup for later use. But now I get an error in logcat. Note that the error doesn't cause a crash ( yet , dunno)

Here is the error:

Task exception on worker thread: java.lang.IncompatibleClassChangeError: The method 'java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir(android.content.Context)' was expected to be of type virtual but instead was found to be of type direct (declaration of 'com.google.firebase.iid.zzg' appears in /data/data/myPackageName/files/instant-run/dex/slice-com.google.firebase-firebase-iid-9.0.0_some-ID-which-I-think-shouldn't-be-exposed-here-classes.dex): com.google.android.gms.measurement.internal.zzt.zzEd(Unknown Source)

So what is this error about? Should I just ignore it and keep going?

Just use compile 'com.google.firebase:firebase-database:10.0.1' instead of compile 'com.firebase:firebase-client-android:2.5.2' in your gradle file. In my case works without erros.
