How can I access playlist created by android default music app and call the music app to play it?

Question

I am writing an android app, and I want to access the playlist created by android default music app.

In my app, the user should be able to browse the playlist and select any playlist to play.

So basically I want to know how to access it and when user selects any playlist, how to pass it to default music app to play it in background.

Is it something to do with ContentProvider or mediastore?? I really don't know how to access data on other apps.

Thank you so much!

To play the songs from above playlists, I m calling the function

PlaySongsFromAPlaylist( PlayListID ); // 0 < PlayListID < count

from the above onCreate method. And remaining code is as per mentioned below.

public void PlaySongsFromAPlaylist(int playListID){

    String[] ARG_STRING = {MediaStore.Audio.Media._ID,MediaStore.Audio.Media.DATA,MediaStore.Audio.Media.DISPLAY_NAME,MediaStore.Video.Media.SIZE,android.provider.MediaStore.MediaColumns.DATA};
    Uri membersUri = MediaStore.Audio.Playlists.Members.getContentUri("external", playListID);
    Cursor songsWithingAPlayList = mThis.managedQuery(membersUri, ARG_STRING, null, null, null);
    int theSongIDIwantToPlay = 0; // PLAYING FROM THE FIRST SONG
    if(songsWithingAPlayList != null)
    {
        songsWithingAPlayList.moveToPosition(theSongIDIwantToPlay);
        String DataStream = songsWithingAPlayList.getString(4);
        PlayMusic(DataStream);
        songsWithingAPlayList.close();
    }   
}

 public static void PlayMusic(String DataStream){
    MediaPlayer mpObject = new MediaPlayer();
    if(DataStream == null)
        return;
    try {
        mpObject.setDataSource(DataStream);
        mpObject.prepare();
        mpObject.start();
    } catch (Exception e) {
        e.printStackTrace();
    }
 }

Hope this will work. :)
