How can I go to new screen(Intent) after logging successfully in Facebook android

Question

I am working on a android application in which I need to open a Facebook login window and then after logging successfully, I need to move to another intent (or new screen) .

So as soon as user is logged in successfully, it should go to another screen in my app. I am having a very hard time making this thing to work. I have got the sample examples from the Facebook SDK so I was testing it out on those examples, I created another screen named Screen2.java(new xml file) having only a single button just to test it out.

So in my case what it should do is as soon as you are logged in successfully it should go to . Screen2 intent . So I made some changes in the Main.java class mentioned here in this tutorial but it is not working for me. Meaning as soon as I am logged in to Facebook, it doesn't goes to .Screen2 intent that I have created. Can anyone help me out here?

I made changes only in Main.java class as below by adding new Intent in the method onAuthSucceed() -

public class SampleAuthListener implements AuthListener {

    @Override
    public void onAuthSucceed() {
        mText.setText("You have logged in! ");
        // mRequestButton.setVisibility(View.VISIBLE);
        // mUploadButton.setVisibility(View.VISIBLE);
        // mPostButton.setVisibility(View.VISIBLE);

        Intent i = new Intent(Main.this, Screen2.class);
        startActivity(i);
    }

    @Override
    public void onAuthFail(String error) {
        mText.setText("Login Failed: " + error);
    }
}

NOTE:- I am able to login into Facebook but after logging successfully, it doesn't goes to my new Intent.

Any help will be appreciated.

I was under the impression you needed something like this

private Session.StatusCallback callback = new Session.StatusCallback() {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        onSessionStateChange(session, state, exception);
    }
};

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    if (state.isOpened()) {
        Log.d(TAG, "Logged in...");
        //fire intent
    } else if (state.isClosed()) {
        Log.d(TAG, "Logged out...");
    }
}
