Answer 1

This method does not need to exist.

public void show(FragmentTransaction manager, Object o) {}

At least, you shouldn't need to override / overload the existing show(FragmentTransaction transaction, String tag) method.

If you delete it, there should be no errors.

This code, for example, compiles fine.

public class MainActivity extends android.support.v7.app.AppCompatActivity {

     public static class PopUpFragment extends android.support.v4.app.DialogFragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.pop, container, false);
            return rootView;
        }
    }

    @Override
    protected void onCreate(Bundle b) {
        super.onCreate(b);
        setContentView(R.layout.activity_main);

        PopUpFragment pop = new PopUpFragment();
        pop.show(getSupportFragmentManager(), null);

    }
}
