UserRecoverableAuthException: NeedPermission

Question

I tried to follow tutorial: https://developers.google.com/android/guides/http-auth.

Code:

token = GoogleAuthUtil.getToken(getApplicationContext(),
           


        

Answer 1

On this docs page https://developers.google.com/+/mobile/android/sign-in the example has a good explanation for this exception.

In particular, it looks like this line should be noted:

Requesting an authorization code will always throw UserRecoverableAuthException on the first call to GoogleAuthUtil.getToken

catch (UserRecoverableAuthException e) {
  // Requesting an authorization code will always throw
  // UserRecoverableAuthException on the first call to GoogleAuthUtil.getToken
  // because the user must consent to offline access to their data.  After
  // consent is granted control is returned to your activity in onActivityResult
  // and the second call to GoogleAuthUtil.getToken will succeed.
  startActivityForResult(e.getIntent(), AUTH_CODE_REQUEST_CODE);
  return;
}
