On a computer your are ok but not on an Android device.
To perform the oauth2 login, the app is forced to send the user to a specific Google webpage. There are only 2 ways to do that, load it inside a WebView within the app or send to an external url to be opened by the phone browser.
In both cases, Android (/Google) will capture that and use the "add account to Android" provider.
Now, let's suppose that you want to use your own custom WebView to avoid that, then the oauth2 page on Google server will perform a check against that and will refuse to load.
Officially "for security reason for the user".
