Answer 1

How do I get the release api SHA1 fingerprint:

install your signed APK, from Playstore, or just copying it to the phone.

Plug USB cable if it is a real phone, and open Android Studio.

The first time you try to get maps, a Log entry will show something like:

E/Google Maps Android API: In the Google Developer Console (https://console.developers.google.com)

Ensure that the "Google Maps Android API v2" is enabled.
Ensure that the following Android Key exists:

API Key: AIzaS

Android Application (;): 56:AF:B2:;br.com.tinx.

then, just follow those instructions, creating a new entry in the Developer Console.

• if you hit your app maps prior seeing the log, you may need to close app from memory and try again)
• this procedure should work on an emulator too.
