Question

Using code from open source MusicDroid with the following code that I found during a search for this problem, I can only get mp3 files that are in the root directory /sdcard/

File home = Environment.getExternalStorageDirectory();

if (home.listFiles( new Mp3Filter()).length > 0) {
    for (File file : home.listFiles( new Mp3Filter())) {
        songs.add(file.getAbsolutePath());
    }
    ArrayAdapter<String> songList = new ArrayAdapter<String>
          (this,R.layout.song_item,songs);
    setListAdapter(songList);
}

How can I get all the mp3 files from the card (in any directory) into my ‘songs’ list?

Answer 1

Depending on what you want, you could just query the media store. Android scans the sdcard every time it is remounted, so MediaStore.Audio should have all the information you need.
