Android: Google Sign In - difference between 'DEFAULT_SIGN_IN' and 'DEFAULT_GAMES_SIGN_IN'
问题 I am trying to implement a Google Sign In into my app in AndroidStudio. I have it working with: GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().requestServerAuthCode(clientID).build(); I have my client ID correctly set up to the Web Application Client ID from the API console and SHA1 is definitely set up correctly. When i change to this (using DEFAULT_GAMES_SIGN_IN instead): GoogleSignInOptions gso = new GoogleSignInOptions.Builder
