Hi I am trying to run an Android Program I have created that can connect to Firebase with Authentication using email and password but it seems that I cannot even authenticat
I had the same issue and spent half a day working it out.
In your emulator, go to settings->apps->Google Play Services and compare the version used to what appears in your build.gradle file.
In my case the emulator was running an earlier version and no amount of updates seemed to change it.
In build.gradle, I changed the following:
compile 'com.google.android.gms:play-services:9.6.1'
to
compile 'com.google.android.gms:play-services:8.+'
After which I restarted android-studio and it worked flawlessly.
