get android release Certificate Fingerprints
Just to test it (with the debug fingerprint), run the following command in any directory with the terminal.
$ keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore -list -v
Then copy the SHA1 value and paste it into your Firebase console.
Be careful, the above will work for the debug environment, if you want to set up the release fingerprint you will have to create a keystore, check out this post to see how to do it, and then run the same command but instead of ~/.android/debug.keystore
you should put ~/YOUR/PATH/TO/KEYSTORE
$ keytool -exportcert -alias androiddebugkey -keystore ~/YOUR/PATH/TO/KEYSTORE -list -v
