I've been searching day and night now for a proper OAuth2 library to use for my android app.
I came across many, including apache amber (formally leeloo) and the android developer specified one (http://developer.android.com/training/id-auth/authenticate.html) which seems to be deceperated.
Yet none of them work or even merge with my project error free (ie. missing methods in jars).
Thus my question is, if there is ANY proper OAuth2 library out there that can be used for android. All I need is a library that allows me to retrieve an authentication code, followed by the token call which will allow autorize requests.
Any links towards an interesting project (git or w/e) are most appreciated.
