موفق باشید

در پوشه value  یک فایل style بسازید

 <?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="NotificationText">
        <item name="android:textColor">?android:attr/textColorPrimaryInverse</item>
    </style>

    <style name="NotificationTitle">
        <item name="android:textColor">?android:attr/textColorPrimaryInverse</item>
        <item name="android:textStyle">bold</item>
    </style>

امیر جان این کد من برای ارسال نوتیفیکیشن api بالای 11:

              Intent intent1 = new Intent(context, khabarNotVojodView.class);   
  PendingIntent pendingIntent =
                        PendingIntent.getActivity(context, 0, intent1, PendingIntent.FLAG_ONE_SHOT);
                NotificationManager nm =
                        (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                Notification.Builder mBuilder = new Notification.Builder(context)
                        .setSmallIcon(R.drawable.iconkochik)
                        .setContentIntent(pendingIntent)
                        .setTicker(KHnotification_description_khabarNotVojod)
                        .setLargeIcon(myBitmap)
                        .setContentText(KHName_khabarNotVojod)
                        .setContentTitle(KHnotification_description_khabarNotVojod)
                        .setAutoCancel(true);
                Notification notif = mBuilder.getNotification();

                nm.notify(321, notif);

و این هم برای زیر 11 هست:

             Intent intent1 = new Intent(context, khabarNotVojodView.class);
    PendingIntent pendingIntent =
                        PendingIntent.getActivity(context, 0, intent1, PendingIntent.FLAG_ONE_SHOT);
                NotificationManager nm =
                        (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notif = new Notification(
                        R.drawable.iconkochik,
                        KHnotification_description_khabarNotVojod,
                        System.currentTimeMillis());
                CharSequence from = KHnotification_description_khabarNotVojod;
                // CharSequence from = "پنح";
                CharSequence message = KHName_khabarNotVojod;
                //  CharSequence message = "برنامه ای بسیار جذاب";
                notif.setLatestEventInfo(context, from, message, pendingIntent);
                nm.notify(321, notif);

اون کدی که دادی باید کجا وارد بشه؟(Remote Views)
