Given an Android music playlist name, how can one find the songs in the playlist?

Question

The playlist names can be found by a query on MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI and then look at the MediaStore.Audio.PlaylistsColumns.NAME<

Answer 1

this is the way to get all playlist from the device

public ArrayList getPlayList() {

            ArrayList arrayList=new ArrayList();

            String[] proj = {"*"};
            Uri tempPlaylistURI = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI;

            // In the next line 'this' points to current Activity. 
            // If you want to use the same code in other java file then activity, 
            // then use an instance of any activity in place of 'this'. 

            Cursor playListCursor= activity.managedQuery(tempPlaylistURI, proj, null,null,null);

            if(playListCursor == null){
                System.out.println("Not having any Playlist on phone --------------");
                return arrayList;//don't have list on phone 
            } 

            System.gc();

            String playListName = null;

            System.out.println(">>>>>>>  CREATING AND DISPLAYING LIST OF ALL CREATED PLAYLIST  <<<<<<");

            for(int i = 0; i  " + i + "  : " + playListName );
                arrayList.add(playListName);
            } 

            if(playListCursor != null)
                playListCursor.close();

            return arrayList;



        }
