Note: There is a known issue running Instant Apps on the emulator image that includes the Google Play Store which will give this same error. For now, please use the emulator without Play Store.
Google Play Services giving statusCode=API_UNAVAILABLE means your device is not able to run Instant Apps for one reason or another. For example, you are not using a supported device or you are not in a launched country. Please see here for a list of supported development devices and here for a list of countries Instant Apps are available in.
The emulator should still work for development and will run outside of any restrictions. For instructions on setting up an emulator for Instant App development see here:
