Set default alarm sound programatically Android

问题

I've been trying to define the default alarm sound but with no success! I can sucessfully change the ringtone and the notification sound but the alarm doesn't change at all... I'm using this code for the alarm:

RingtoneManager.setActualDefaultRingtoneUri(getActivity(), RingtoneManager.TYPE_ALARM, Uri.parse(uri+"/"+id));

Many thanks!

Try this

 try {
            RingtoneManager.setActualDefaultRingtoneUri(getContext(),
                    RingtoneManager.TYPE_ALARM, newUri);
            Settings.System.putString(mCr, Settings.System.ALARM_ALERT,
                    newUri.toString());
            Toast.makeText(getContext(), "Done", Toast.LENGTH_SHORT).show();

        } catch (Throwable t) {

        }
