I want to add a youtube fragment into my already existing fragments dynamically. The code I used is below:
        // setting the Youtube Player Dynamically
private int setYoutubePlayer(String desc, View view, int prevID,
        Bundle input) {
    if (desc.indexOf("=") != -1) {
        desc = desc.substring(desc.indexOf("=") + "=".length());
    } else {
        return prevID;
    }
    final String url = desc;
    LinearLayout videoLayout = new LinearLayout(view.getContext());
    videoLayout.setOrientation(LinearLayout.VERTICAL);
    prevID++;
    videoLayout.setId(prevID);
    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager
            .beginTransaction();
    fragment.setVideoId(url);
    LinearLayout itemLayout = (LinearLayout) view.findViewById(R.id.items);
    itemLayout.addView(videoLayout);
    fragmentTransaction.add(itemLayout.getId(), fragment,
            "youtube fargment " + prevID);
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();
    return prevID;
}
I need to get the youtube fragment in the appropriate fragment. As I checked when always a new fragment get loaded (when swipe between fragments), the new inner fragment needs to be the first loaded fragment.
Any help will be gladly accepted.
SOLVED: Thank you Koby You were right. i had to replace "getActivity().getSupportFragmentManager();" with "getChildFragmentManager()". The problem was apparently the Sherlock library came with a old android v4 support library. I had to update the support library in the Sherlock. It worked for me.....
