Android Notification buttons not showing up

Question

This is my code to set up a notification with buttons.

Intent receiverIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pReceiverIntent = PendingIntent.getActivity(ctx, 1, receiverIntent, 0);
        Intent clearIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        clearIntent.setAction("clear");
        PendingIntent pClearIntent = PendingIntent.getActivity(ctx, 1, clearIntent, 0);

        Intent colorsIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        colorsIntent.setAction("colors");
        PendingIntent pColorsIntent = PendingIntent.getActivity(ctx, 1, colorsIntent, 0);

        Intent animationIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        animationIntent.setAction("animation");
        PendingIntent pAnimation = PendingIntent.getActivity(ctx, 1, animationIntent, 0);

        Notification.Builder builder;
        builder = new Notification.Builder(ctx).setSmallIcon(R.drawable.ic_launcher).setAutoCancel(false)
                .setContentTitle("Draw Me: A Live Wallpaper").setContentText("Never get bored again!")
                .setContentIntent(pReceiverIntent).addAction(R.raw.ic_menu_close_clear_cancel, "Clear", pClearIntent)
                .addAction(R.raw.ic_menu_edit, "Colors", pColorsIntent).addAction(R.raw.ic_menu_play_clip, "Animation", pAnimation);
        Notification notification = builder.build();

        NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notification);

Notification is showing up but buttons don't. My device has Android 4.1.1 I set up this notification in a Fragment. What am I doing wrong? Thanks!

Let me tell you something which is really awkward. If you have anything in your Ongoing Notification, You wont see the buttons. Typically it happens when you have phone connected to PC via USB. Hope this solves your problem
