Answer 1

A possible walkthrough would be to downgrade the emulator's API version (e.g. from 23 to 20) by creating a new emulator (Tools -> Android -> AVD Manager -> Create New Virtual Device. On the second screen, select your prefered (e.g. 20) API version.

Answer 2

The updated Android tools (which contains the Android Emulator system image) isn't out yet. Only once that is out will your emulators have Google Play Services 9.8, which is a prerequisite for Firebase SDK 9.8.

If you want to test on an emulator, you will have to downgrade your app to Firebase SDK 9.6 for the moment.

If you deploy to a physical device, it'll likely already have the latest version.
