Sign in onResume #2
Description
If activity is in the background for a while, the app loses sign-in status, and cant open for example leaderboard.
According to Google docs, sign in should be called onResume
Since the state of the signed-in player can change when the activity is not in the foreground, we recommended calling silentSignIn() from the activity's onResume() method.
