Yahoo Integration in Android

I plan to integrate Yahoo into my Android app to get the name and personal data of the user. How to integrate Yahoo with Android?

I spent several hours searching for a tutorial / sample Android application that integrates a Yahoo account using OAuth, but I cannot find it.

Take a look at the following code: you need a Signpost library Pointer library

import oauth.signpost.OAuth; import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer; import oauth.signpost.commonshttp.CommonsHttpOAuthProvider; import oauth.signpost.exception.OAuthCommunicationException;
