Go to this path or where ever you have your keytool.exe file
C:\Program Files\Java\jre7\bin
Hold
shift and right click -> then press Open command window here
terminal will pop up, paste this in:
keytool -list -v -keystore "C:\Users\"Your-User-Name(no quotes)"\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
You should see some lines with letters and numbers.
Find the line that begins by SHA1, like this one:
- SHA1 : 84:BD:28:73:1B:6F:C2:84:2C:8D:03:11:56:19:E4:KD:38:C3:80:73
It's what we call a certificate fingerprint.
At this point, we have to take this SHA1 certificate fingerprint and transform it into a real key to put in our XML code.
And for that it's time to go to the Google APIs website.
