Estoy intentando configurar el ícono de la barra de estado de notificaciones como animado android.R.drawable.stat_sys_upload, funciona bien, pero el ícono no se anima:

private void showStatusNotification() {

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

    Builder notificationBuilder = new NotificationCompat.Builder(this);
    notificationBuilder.setAutoCancel(false);
    notificationBuilder.setOngoing(true);
    notificationBuilder.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(this,
            MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT));
    notificationBuilder.setContentTitle(getString(R.string.notification_title));
    notificationBuilder.setContentText(getString(R.string.notification_text));
    notificationBuilder.setSmallIcon(android.R.drawable.stat_sys_upload);
    notificationManager
            .notify(STATUS_NOTIFICATION_ID, notificationBuilder.build());
}
