NPE when resuming AuthenticationActivity

[twaddington]

Has anyone else encountered this error?

After calling WebAuthProvider.init(auth0)...start() to display the chrome tab view simply tapping "Back" or the "Close" button results in a crash:

This looks like a problem with the logic in AuthenticationActivity#onResume.

I could reproduce it by asking for response_type=code+id_token. I'll look into it. Thanks

This should be fixed in the latest patch. Please try 1.10.1 and reopen if necessary.
