Facebook login in fragment in android

You just need to add this code in your Activity onActivityResult.

for (Fragment fragment : getSupportFragmentManager().getFragments()) {            //System.out.println("@#@");            fragment.onActivityResult(requestCode, resultCode, data);        }

Then your fragment onActivityResult will surely gonna work.

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

Yes it's Posssible to implement facebook login in fragment, the only thing you need to do is call OnActivityResult in your host activity like this:

@Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        Fragment fragment = getFragmentManager().findFragmentById(R.id.your_host_fragment_in_activity);        fragment.onActivityResult(requestCode, resultCode, data);    }

and then call onActivityResult again in yout fragment.

You just need to add one line inside fragment

fbLoginButton.setFragment(this);

You will get the control in

@Overridepublic void onActivityResult(int requestCode, int resultCode, Intent data) {}
