4. Once you are in the “.android” directory, run the following command.keytool -exportcert -alias androiddebugkey -keystore debug.keystore | openssl sha1 -binary | openssl base64


Note: “androiddebugkey” can be the username for the keystone file and “debug.keystore” can be the name of the keynote file 

1. When it prompts you for a password, type android and hit Enter
