Question

Answer 1

They are asking for the SHA1 fingerprint on your keystore file (You sign your apps using this before you can push them to google play)

you can get your key by doing this

keytool -exportcert -alias your-key-name -keystore /path/to/your/keystore/file -list -v

you can use your keystore file from another computer just put it on a USB stick or email it to yourself (Make sure to keep it private !IMPORTANT!) and point your IDE to the file
