Followers, Following and Tweets (just the number) knowing the user ID

[postllisas]

I am using Fabric Twitter on android, I just want to get the followers, following and tweets (the number) from one user whose ID I know, so I am not going to use the TwitterLoginButton for a Login, I have found a few examples but always with the login button.
Anybody can tell me how I can implement it?
I am stack here:

final String TWITTER_KEY = “1231231321”;
final String TWITTER_SECRET = “123123131”;
TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
Fabric.with(getContext(), new Twitter(authConfig));

    TwitterApiClient twitterApiClient = TwitterCore.getInstance().getApiClient();
    StatusesService statusesService = twitterApiClient.getStatusesService();
