Android Twitter Login button not working

Question

I'm writing an application that includes a sign in with twitter button. The button is okay. It shows on the screen when I click I give auth but I cant save the token and secret to a string variable. I mean it is empty always. The code at the below has been created by fabric.io automatically and I have added some stuff in it but it is not working. There is no error it just doesn't change the variable token and secret. I have tried this by an TextView object that changes in the success case and it never changes. What should I do? I just want to save token and secret to get user's information another time.

loginButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);
    loginButton.setCallback(new Callback<TwitterSession>() {
        @Override
        public void success(Result<TwitterSession> result) {
            System.out.println("Okay we are logged in now!");

            TwitterSession session = Twitter.getSessionManager().getActiveSession();
            TwitterAuthToken authToken = session.getAuthToken();
            token = authToken.token;
            secret = authToken.secret;
            String answers = "";
            User user = new User(userid,token,secret,answers);
            registerUser(user);
            twitterauth = true;
        }

        @Override
        public void failure(TwitterException exception) {
            // Do something on failure
        }
    });

EDİT: I'm taking an error like the following, if I click the sign in with Twitter button again:

2660-2660/com.website.nameofmyapp E/Twitter﹕ Authorization completed with an error

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1195)

All I want to do is simple to start a new activity when "success" happens automatically.

Answer 1

Two points helped me in this -

1- In MainActivity.java add this

    TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
    Fabric.with(this, new Twitter(authConfig));

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    FragmentManager fragment = getSupportFragmentManager();
    if (fragment != null) {
        fragment.findFragmentByTag("TwitterLogin").onActivityResult(requestCode, resultCode, data);
    }
    else Log.d("Twitter", "fragment is null");
}

2- In your fragment class add this-

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    loginButton.onActivityResult(requestCode, resultCode, data);
}
