I'm planning to integrate Yahoo in my Android Application to get the name and personal details of a user. How do I integrate Yahoo with android?
I have spent several hours looking for a tutorial/sample android application that integrates Yahoo login using OAuth, but I can't find one.
Look at the following code , You need Signpost library Signpost Library
import oauth.signpost.OAuth;
import oauth.signpost.commonshttp.CommonsHttpOAuthConsumer;
import oauth.signpost.commonshttp.CommonsHttpOAuthProvider;
import oauth.signpost.exception.OAuthCommunicationException;
import oauth.signpost.exception.OAuthExpectationFailedException;
import oauth.signpost.exception.OAuthMessageSignerException;
import oauth.signpost.exception.OAuthNotAuthorizedException;
import oauth.signpost.signature.HmacSha1MessageSigner;
