Android music files location?

Question

I'm writing a music player app and I'm wondering where should I look for the user's music files. I want to find all the songs that the Music app normally finds and I'm curious how that app finds the songs. Is there an enum variable for a specific folder? Just a recursive search of the sd card? I know on my phone's sd card there's a Music folder; is that how it is on every android device and should I just recursively search that folder? Or should I just ask the user to find the folder?

Answer 1

You can find all music files from sdcard using below function.

public void getAllSongsFromSDCARD() 
{
    String[] STAR = { "*" };        
    Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";

    cursor = managedQuery(allsongsuri, STAR, selection, null, null);

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do {
                String song_name = cursor
                        .getString(cursor
                                .getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                int song_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media._ID));

                String fullpath = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.DATA));


                String album_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM));
                int album_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

                String artist_name = cursor.getString(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST));
                int artist_id = cursor.getInt(cursor
                        .getColumnIndex(MediaStore.Audio.Media.ARTIST_ID));



            } while (cursor.moveToNext());

        }
        cursor.close();
    }
}

Android automatically scans all external SD cards for audio and indexes this data, see the MediaStore.Audio class for details. This allows you to query by Albums, Artists, Genres and Playlists. If you just want a list of media files can be found by querying the content provider MediaStore.Audio.Media.EXTERNAL_CONTENT_URI.
