Navigating and sending data from activity to fragment

Question

I created a navigation drawer. Now,navigation drawer requires all fragments. I want to send some information and move to this fragment which contains drawer from an activity. How do I implement this ? I am using Intent(activityclass.this,fragment.class) for navigation and putExtra for sending data. But the app crashes.

Answer 1

Fragments are not loaded using Intent. You need to use FragmentManager:

 Fragment fragment = new MyFragment();
 FragmentManager fragmentManager = getFragmentManager();       
 fragmentManager.beginTransaction().replace(R.id.container,fragment).commit();
