For me the function cardScrollView.setSelection(cardScrollView.getSelectedItemPosition() + 1) doesnt seem to work.
Im calling the function after my glass receives a message from my nodeJs server, but it just doesnt seem to do anything. It's not showing me another card.
When I call cardScrollView.getSelectedItemPosition() I DO get the currently selected index however.
Maybe I'm doing something wrong?
Here is the mainActivity with where Im trying to call the function (The line I'm talking about is in the client.on("event", new EventCallback() function):

Does somebody have any suggestions? I've spend a few hours of research on this and I'm pulling my hair out.
Thanks!
