  1. When i create a Blank Activity with Fragment it creates me an activity that extends from ActionBarActivity and then creates a class that extends from Fragment, how can i execute my MainFragment from an class that extends form ActionBarActivity.

  2. Your tutorial is great and helped me a lot but I want to create the login button on a popup window, how should I do that? and how can I hide the login button when the user has already loged in? and will you do some tutorials on facebook sharing and like button too?

  3. Is there a way to use the FB SDK log in button without using a fragment? Can I just put it straight on the MainActivity? If so, how do I do this?

  4. Thanks man! I got your site after one week and you wont believe even after trying millions of options it dint work. Amazing work 😀

  8. Hi, great tutorial but i seem to have an error through your code. when i run inspect code in android studio it comes up with an error such as…

     class anonymous in FacebookCallback callback (mobliedevelopment.terrelsimeongordon.hwl_fb.MainFragment)  

     Problem synopsis     
     Variable ‘accessToken’ at line 38 is never used

    i downloaded the source code yet the same error comes up

    this is the code that android is complaining about?

    private FacebookCallback callback = new FacebookCallback() {
    public void onSuccess(LoginResult loginResult) {
    AccessToken accessToken = loginResult.getAccessToken();
    Profile profile = Profile.getCurrentProfile();

    do you have any clue why it is not working and why it can not find accessToken? grateful if you could help answer this 1 million dollar question 🙂

  15. Hi,

    I am able to integrate facebook login into my app successfully by follwing your post. The actual req of my app is to trigger facebook status at the end of every month. When i try to login after two months login dialog does not open up. It throws a FacebookAuthorizationException. Can you please help me in figuring it out.

    Note: I believe due to access token expiry facebook login dialog does not open. You can check it
