Looking for working (complete project) example for OAuth 2.0 Access to gmail [closed]

Question

I have read Oauth2 Docs but still am yet to get a start to finish working example.

I am a beginner and struggling to get a solution working.

I am just about to the point where I am willing to pay someone to code this for me. But it seems like it should be fairly simple and that there has to be a start to finish working example out there.

So, do you have an example of an Android app that uses OAuth 2.0 to enable the sending of email via gmail? I also need an example of using the users contacts to prepopulate a list for the user to choose from as the recipient of the email.

If I could find a free, complete example I would be indebted forever.

NOTE: I posted a similar question here... looking for Android Gmail SMTP Oauth example

And the answer was good but being a beginner I was never able to get it to work.

thanks for any help.

Answer 1

I didn't have time to implement Google OAuth2,
but I can suggest you to make use of this open source library.

generic oauth2 login for android

covers OAuth2 implementation for Facebook, Foursquare, Gowalla.
I would assume that should be easy to extend for Google, as OAuth2 is pretty much standard and communities differs mostly on loading user profile part.
