Why doesn't Android Facebook interface work with Fragments?

Question

I\'m switching some Android Facebook code from an Activity to a Fragment. Prior to the switch everything worked fine, but now the

Answer 1

Facebook SDK don't works with Fragment, but works with FragmentActivity. So you need:

1. Catch the FB login info in onActivityResult() in your parent FragmentActivity.
2. Pass activity results to your child Fragment

example:

1.

public class MainActivity extends FragmentActivity(){


/* catch FACEBOOK login info and call onFBLoginActivityResult() to pass it to FacebookFrragment*/
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

       android.support.v4.app.FragmentManager fm =   getSupportFragmentManager();
       FacebookFragment fbfragment= (FacebookFragment ) fm.findFragmentByTag("facebookfragment");
       selectPKEConfigFragment.onFBLoginActivityResult(requestCode, resultCode, data);

    }

}

2.

public class FacebookFragment extends Fragment{

        @Override
            public View onCreateView(LayoutInflater inflater, ViewGroup container, 
                Bundle savedInstanceState) {
        // ........... 

         // start Facebook Login

                    Session.openActiveSession(getActivity(), true, new Session.StatusCallback() {

                      // callback when session changes state
                      @Override
                      public void call(Session session, SessionState state, Exception exception) {
                        if (session.isOpened()) {
                          // make request to the /me API
                          Request.executeMeRequestAsync(session, new Request.GraphUserCallback() {

                            // callback after Graph API response with user object
                            @Override
                            public void onCompleted(GraphUser user, Response response) {
                              if (user != null) {
                               // TextView welcome = (TextView) findViewById(R.id.welcome);
                               // welcome.setText("Hello " + user.getName() + "!");
                                  Log.i(TAG,"User: " + user.getName());
                              }
                              else  Log.i(TAG,"User: null");
                            }
                          });
                        }
                        else Log.i(TAG,"session closed");
                      }


                    });

            }

        /*
         * replace onActivityResult
         */
        public void onFBLoginActivityResult(int requestCode, int resultCode, Intent data){
             Log.i(TAG,"Activity result SelectPKEConfig");
            Session.getActiveSession().onActivityResult(getActivity(), requestCode, resultCode, data);
        }
