How to share a mp3 in raw folder with whatsapp? I try this, but doesnt work!!!!

Uri path =  Uri.parse("android.resource://my.path.sound/raw/sound");
Intent waIntent = new Intent(Intent.ACTION_SEND);
waIntent.setType("audio/mp3");
waIntent.setPackage("com.whatsapp");
waIntent.putExtra(Intent.EXTRA_STREAM, path);
startActivity(Intent.createChooser(waIntent, "Share with"));
