鈴聲的來源可以是內建在應用程式內部raw目錄下的資原始檔，也可以通過開啟系統鈴聲選擇頁面去選擇：

1、內建在應用程式內部raw目錄下的資原始檔

notification.sound = Uri.parse("android.resource://" + getPackageName()  
                + "/" + R.raw.sound_pull_down);

2、通過開啟系統鈴聲選擇頁面去選擇

Intent i = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
			i.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_DEFAULT, true);
			i.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_NOTIFICATION);
			i.putExtra(RingtoneManager.EXTRA_RINGTONE_SHOW_SILENT, false);
			Uri ringtongUri = null;
			String uri = SharedPreferenceUtil.getInfoFromShared(SharedPreferenceUtil.KEY_NOTIFY_SOUND_URI);
			if (!ResourceUtils.isEmpty(uri)) {
				ringtongUri = android.net.Uri.parse(uri);
			} else {
				ringtongUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
			}
			
			i.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, getString(R.string.notification_ringtong));
			i.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, ringtongUri);
			startActivityForResult(i, REQUEST_NOTIFY_SOUND);
 

	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (requestCode == REQUEST_NOTIFY_SOUND) {
			if (resultCode == RESULT_OK) {
				Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
				// RingtoneManager.isDefault(uri);
				if (uri != null) {
					String ringTonePath = uri.toString();
					SharedPreferenceUtil.setInfoToShared(SharedPreferenceUtil.KEY_NOTIFY_SOUND_URI, ringTonePath);
				} else {
					SharedPreferenceUtil.setInfoToShared(SharedPreferenceUtil.KEY_NOTIFY_SOUND_URI, "");
				}
