how to add Follow or create Friendship using Fabric sdk

how to add Follow or create Friendship using Fabric sdk for twitter android app here is the link https://docs.fabric.io/android/twitter/index.html i am unable to get information from fabrics docs for follow

here is the answer Actually its required end point to be made for the api calls which is not available already

public class TwitterFollow extends TwitterApiClient {
        public TwitterFollow(TwitterSession session) {
            super(session);
        }
        public FollowService getFollowService() {
            return getService(FollowService.class);
        }

        /*interface used for Auth Api call for CreateFriendship*/
        public interface FollowService {
            @POST("/1.1/friendships/create.json")
            public void create(@Query("screen_name") String screen_name, @Query("user_id") String user_id, @Query("follow") boolean follow, Callback<User> cb);
        }
    }

and then using it

TwitterFollow apiClient = new TwitterFollow(session);
apiClient.getFollowService().create(TWITTER_ACCOUNT_NAME, null, true, new Callback<User>() {
                            @Override
                            public void success(Result<User> result) {
                                Toast.makeText(this, "Thanks for following!", Toast.LENGTH_SHORT).show();
                            }

                            @Override
                            public void failure(TwitterException e) {
                                Toast.makeText(this, "Error following", Toast.LENGTH_SHORT).show();
                            }
                        });
