“Activity not found” in Android

Question

I am using the navigation-drawer template in eclipse to do a simple Android application. I have some trouble with fragment. I declared a fragment called PresenceL

Answer 1

You have created a Fragment so you could not call it like a Activity. You need to replace a container view, properly an FrameLayout with your Fragment.

getSupportFragmentManager()
  .beginTransaction()
  .replace(R.id.content_frame, new PresenceLogFragment())
  .commit();
