Android: support package Fragment

Question

I tried this example

I build for API Level 15 and use support package as well. This funktion causes trouble:

@Override
        public Fragment getItem(int position) {
            return ArrayListFragment.newInstance(position);
        }

Error Message:

The return type is incompatible with FragmentPagerAdapter.getItem(int)

Make sure you are using this class: android.support.v4.app.Fragment instead of android.app.Fragment

Import android.support.v4.app.Fragment instead of android.app.Fragment.
Get the fragment manager using getSupportFragmentManager() instead of getFragmentManager()

thants what eclipse suggested. AT Override public android.support.v4.app.Fragment getItem(int position) { return ArrayListFragment.newInstance(position); brings: Type mismatch: cannot convert from MenuFragen.ArrayListFragment to Fragment like in the example i use getSupportFragmentManager @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.menufragen); mAdapter = new MyAdapter(getSupportFragmentManager()); – user1324936 Apr 17 '12 at 19:14
