Android YouTube-Sign-In alternatives to WebView

view story

http://stackoverflow.com – I created an android application which allows the user to sign in to YouTube in a WebView. After that, the user get an access token (OAuth 2.0) and can access his favorite videos. This works fine, but doing a Sign In in a WebView seems no to be the nicest solution. Is there a way to provide YouTube authentication without using a WebView? ( for implementing OAuth, i followed this tutorial: http://blog.blundell-apps.com/tut-oauth-youtube-api-access/ ) (HowTos)
