This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I have noticed that on Mobile applications when you transition between Activities, if drawing the View hierarchy of the new Activity takes time we see a blank, dark screen. This is the default background for the Window. I know that this can be avoided most of the times by offloading time consuming tasks to background Threads and making (Activity Life cycle)callbacks return ASAP.
However, my question is -
Is it possible to change this background? Like give it a color consistent with applications theme or maybe even have a video stream playing in background? We can then have Activities just painted on top of it?
