Fragments starting twice

Question

I have this app in which im using fragments, but somehow everytime I start the app, every activity(fragment) is started two times. I\'m banging my head about this but I cannot f

Answer 1

Maybe using a newInstance method will correct this starting of two fragments. Ad populum I see alot of newInstance code when I'm looking at fragment examples.

public class MainFragment extends Fragment {

public static Fragment newInstance(int instance# pass in receipieces and cats here) {
    MainFragment f = new MainFragment();
    // Supply num input as an argument.
    Bundle args = new Bundle();
    args.putParcelableArrayList("all", recepies);
    args.putSerializable("cats", cats);
    args.putParcelableArrayList(Constants.MAINRECEPIES, mainRecepies);
    args.putBoolean("search", true);
    fragment.setArguments(args);
    return f;
}

meanwhile back in the activity that shows the fragment use new instance to start the fragment.

private void showMainFragment() {
    Fragment fragment = MainFragment.newInstacne(instance# pass in recipies and cats here);

    FragmentManager fragmentManager = getFragmentManager();
    fragmentManager.beginTransaction().add(R.id.content_frame, fragment)
            .commit();

}
