The longRoutine is the drawing procedure which may take up to several
seconds.
Yep, I tried to relay that onto another thread and draw into the
SurfaceView but the problem I've faced is that
the original view(s) are still repainted with onDraw() thus the content
(the background thread is rendering all the time) is missing. It's
called from the deep android internals so I don't believe I trigger it
somehow - it's
just a reaction on the invalidate().
Well, it is covered with blank rectangle but I can see the actual
content under that rectangle.
BTW that looks like a thread condition over there as sometimes (very
rarely) I can see the content for a few moments which then becomes
covered with background color.
So far I also tried to:
a) setWillNotDraw(true);
b) unset the background color of the view
Interestingly that in a sample application (a SurfaceView in a
RelativeView) the b) approach does help and since that we don't have
such a problem there.
So the problem now could be read like this (I'm starting to think there
is no way to peek events from the queue, right? :) :
How to switch the SurfaceView's onDraw() method off?
Any cluea of what can make it been called also appreciated.
Thanks,
Andrei

I want it to implement the break for the routine running on the UI thread.
private void longRoutine() {
while (flag){
if (queue.peekMessage() != null) {
return;
}
<whatever the code is>
}
}
Or am I missing something and actually a way exists?
It's called a "background thread". All the cool programmers use them.
Why do you think that you need longRoutine() to be on the main
application thread?
