Is there a library like RPX for Android?

Does someone know of a library that is fairly "drop in" and allows you to easily put together multiple authentication options开发者_开发问答 in an Android app to services like Facebook, OpenID, Twitter, etc. much like RPX does?

Make a little HTML page with RPX embedded inside it (like a real site) inside your res folder and render it using WebView. You would need WebView anyways since as a requirement of OpenID and OpenAuth and everything needs you to go to their site. So in the end, you would need to load up a WebView to show the user that screen anyways.
