自定义通知声音,android奥利奥？

private void sendMyNotification(String messagE) {
    Intent intent;
    if (sharedPreferences.getBoolean(SPConstants.IS_LOGGED_IN,falsE)) {
        intent = new Intent(this,ActivityNotification.class);
    } else {
        intent = new Intent(this,ActivitySplash.class);
    }
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOp);
    PendingIntent pendingIntent = PendingIntent.getActivity(this,intent,PendingIntent.FLAG_ONE_SHOT);
    Uri soundUri = @L_475_4@manager.getDefaultUri(@L_475_4@manager.TYPE_NOTIFICATION);
    soundUri = Uri.parse("android.resource://" + getApplicationContext().getPackagename() + "/" + R.raw.panic);
    Au@L_121_6@manager manager = (Au@L_121_6@manager)getSystemservice(Context.AUdio_serviCE);
    manager.setStreamVolume(Au@L_121_6@manager.STREAM_MUSIC,100,0);
    NotificationCompat.builder notificationBuilder = new NotificationCompat.builder(this,CHAnnEL_ID)
            .setsmallIcon(R.mipmap.ic_launcher)
            .setContenttitle(getString(R.String.app_Name))
            .setContentText(messagE)
            .setAutoCancel(true)
            .setSound(soundUri)
            .setContenTintent(pendingIntent);
    notificationmanager notificationmanager =
            (notificationmanager) getSystemservice(Context.NOTIFICATION_serviCE);
