List all music in MediaStore with the PATHs

Question

Ok so I've been working on this project for a few days now and most of my time has been working out how to list all the music on a device in a LIST VIEW or something else, I have searched for a few days now and this is killing me. I did get so close at one point with all the music in one folder showing, though since most people will have sub folders for things like artiest and albums I need a way to search sub folders for MP3s or music files.

Here is what I have so far for Music collection:

package com.androidhive.musicplayer;

import java.io.File;
import java.io.FilenameFilter;
import java.util.ArrayList;
import java.util.HashMap;

import android.provider.MediaStore;

public class SongsManager {
// SDCard Path
final String MEDIA_PATH = new String(MediaStore.Audio.Media.getContentUri("external").toString());
private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();

// Constructor
public SongsManager(){

}

/**
 * Function to read all mp3 files from sdcard
 * and store the details in ArrayList
 * */
public ArrayList<HashMap<String, String>> getPlayList(){
    File home = new File(MEDIA_PATH);

    if (home.listFiles(new FileExtensionFilter()).length > 0) {
        for (File file : home.listFiles(new FileExtensionFilter())) {
            HashMap<String, String> song = new HashMap<String, String>();
            song.put("songTitle", file.getName().substring(0, (file.getName().length() - 4)));
            song.put("songPath", file.getPath());

            // Adding each song to SongList
            songsList.add(song);
        }
    }
    // return songs list array
    return songsList;
}

/**
 * Class to filter files which are having .mp3 extension
 * */
class FileExtensionFilter implements FilenameFilter {
    public boolean accept(File dir, String name) {
        return (name.endsWith(".mp3") || name.endsWith(".MP3"));
    }
}

}

Thanks to anyone who can help. :)

Answer 1

Although, the post is old, for other people like me to get the idea of creating a list of music with their file path, I added the solution here. MediaStore.Audio.Media.DATA column actually contains media file path. You can get necessary information by using the following snippet:

ContentResolver cr = getActivity().getContentResolver();

Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + "!= 0";
String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
Cursor cur = cr.query(uri, null, selection, null, sortOrder);
int count = 0;

if(cur != null)
{
    count = cur.getCount();

    if(count > 0)
    {
        while(cur.moveToNext())
        {
            String data = cur.getString(cur.getColumnIndex(MediaStore.Audio.Media.DATA));
            // Add code to get more column here

            // Save to your list here
        }

    }

    cur.close();
}
