Later this year, the Google Play services and Firebase SDKs will migrate from the Android Support libraries to androidx-packaged library artifacts. We are targeting this change for June/July of 2019. This will not only make our SDKs better, but make it easier for you to use the latest Jetpack features in your app.

If your app depends on any com.google.android.gms or com.google.firebase libraries, you should prepare for this migration. To quickly test your build with androidx -packaged library artifacts, add the following two lines to your gradle.properties file:

android.useAndroidX=true android.enableJetifier=true
