This example demonstrates how to fetch the URI’s of system ringtones (RingtoneManager.TYPE_RINGTONE):

private List<Uri> loadLocalRingtonesUris() {
        List<Uri> alarms = new ArrayList<>();
        try {
            RingtoneManager ringtoneMgr = new RingtoneManager(getActivity());
            ringtoneMgr.setType(RingtoneManager.TYPE_RINGTONE);

            Cursor alarmsCursor = ringtoneMgr.getCursor();
            int alarmsCount = alarmsCursor.getCount();
            if (alarmsCount == 0 && !alarmsCursor.moveToFirst()) {
                alarmsCursor.close();
                return null;
            }

            while (!alarmsCursor.isAfterLast() && alarmsCursor.moveToNext()) {
                int currentPosition = alarmsCursor.getPosition();
                alarms.add(ringtoneMgr.getRingtoneUri(currentPosition));
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }

        return alarms;
    }

The list depends on the types of requested ringtones. The possibilities are:

• RingtoneManager.TYPE_RINGTONE
• RingtoneManager.TYPE_NOTIFICATION
• RingtoneManager.TYPE_ALARM
• RingtoneManager.TYPE_ALL = TYPE_RINGTONE | TYPE_NOTIFICATION | TYPE_ALARM

In order to get the Ringtones as android.media.Ringtone every Uri must be resolved by the RingtoneManager:

android.media.Ringtone osRingtone = RingtoneManager.getRingtone(context, uri);

To play the sound, use the method:

public void setDataSource(Context context, Uri uri)

from android.media.MediaPlayer. MediaPlayer must be initialised and prepared according to the State diagram
