Well I have some kind of a Drawing view in the second tab, and that view is being drawn from outside, which works...even if that View is not in focus.
Now, On the first tab, I have a button which when clicked, tries to save the Drawing view's content to a file as an image. At this point, when I call getDrawingCache to get the bitmap, it always returns null. But, if I just, for once, switch over to the second tab, I always get a valid bitmap of that drawing view.
