Answer 1

Try this, it works for me

Step 1) Project Structure -> select project -> go to "signing" and select default or any keystore and fill proper details. In case you are not able to fill the details, click the green '+' button. Step 2) Goto Build Types -> select your build type and select your "Signing Config"-> select "config". Step 3) Create new SHA-1 key and add in google console credential.

Answer 2

You will need to add your SHA-1 key to the google cloud console project

Answer 3

You need add release apk sha1. If you added sha1 when your app in debugMode it will only work on Debug APK. So you have to create a sha1 by your release APK keystore,

keytool -exportcert -keystore keystorePath -list -v
