I want to receive audio files in SD card

MediaScanner finds music for you by populating the MediaStore database. Here's some code to find music:

final Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    final String[] cursor_cols = {
            MediaStore.Audio.Media._ID,
            MediaStore.Audio.Media.ARTIST,
            MediaStore.Audio.Media.ALBUM,
            MediaStore.Audio.Media.TITLE,
    };
    final String where = MediaStore.Audio.Media.IS_MUSIC + "=1";
    final Cursor cursor = getContentResolver().query(uri, cursor_cols, where, null, null);
    cursor.moveToNext();
    final String artist = cursor.getString(_cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST));
    final String album = cursor.getString(_cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM));
    final String track = cursor.getString(_cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE));
    doSomethingHere(artist, album, track);

      

        
        
        
      

    

The data field contains a descriptor that you can use with the MediaPlayer. when first crawling and indexing the media, scan it with AsyncTask, but later when intent is received, use it with the service.
