ClassCastException fragments.MainActivity must implement OnHeadlineSelectedListener | classcastexception-fragments-mainactivity-must-implement-onheadlineselectedlistener


Problem:
You have two class with similar names HeadLinesFragment and HeadMyLinesFragment with OnHeadlineSelectedListener.
Check if call correct class in MainActivity.
For example if use HeadMyLinesFragment change implement to HeadMyLinesFragment too!


public class MainActivity extends FragmentActivity 
        implements HeadLinesFragment.OnHeadlineSelectedListener { 
// wrong implements you need correct class name 
//implements  HeadMyLinesFragment.OnHeadlineSelectedListener
//............
HeadMyLinesFragment firstFragment = new HeadMyLinesFragment(); // because in code using HeadMyLinesFragment
