But how? Kostya, Now I know for sure it's doable since you just released upgrades to your widgets that do it! Unfortunately, and I admit that I am being obtuse, I'm still not getting it. When I call RemoteViews.setInt(id,"setAlpha",value) what am I supposed to be passing in for the id parameter? It's not the layout id since that does not have a setAlpha method. I tried sending in the id of my background drawable but that gave me an error that it could not find the view. What's the magic incantation?
