I'm using minSDK = 8 and targetSDK = 17
At activity start, my 3 screens (3 different Views) are set to invisible in the XML layout. In onResume, I call setScreen(1), which starts an animation that sets View 'wait' to visible. However, at line 34 where 'wait' is set to visible, nothing happens. If I remove the comment // from line 43 where 'main' is set to invisible, 'wait' becomes visible.
Why does 'wait' not appear when line 43 is commented out? Why does it take setting the already invisible 'main' View to invisible for 'wait' to appear?
