Facebook login in fragment in android

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 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);
        }
