Another black screen when exiting app via Home

in Android Processing • 3 years ago

I recently added a separate thread to my program - images seem to load (much) quicker now as compared to when they were loaded in the setup routine. However, this seems to cause the black screen when I start the app again. The same phenomenon was described here but was "fixed" when using A3D in the size() command. The issue has cropped up again now that I have started to use a separate thread.

The code is basically set up like this:

void setup(){
...
imageThread = new imageThread(); // loads images faster
imageThread.start();
}
void draw(){
...
}
private class imageThread extends Thread{
imageThread();
public void run() {
// Load images here.
}
}

Note: Using System.Exit(0) seemed to fix the black screen problem but that may have it's own issues...

I'd recommend using requestImage() instead of loadImage(), it takes care of the threading for you.

The black screen issue is on the list to be checked into.

Thanks for replying.

requestImage() does in fact work; I placed it inside draw(). It seems to bring about the same black screen issue however, and I don't think System.Exit(0) "fixes" the black screen in this case. Maybe that helps figure out the black screen issue? The issue occurs whether I use a separate thread or if threading is performed inside requestImage(). ~~And the following code only seemed to helped when my separate thread was used.~~ <-- May not be true... the black ~~smoke monster~~ screen does not rear it's ugly head when using my separate thread and using if (bSetup == true) {System.Exit(0);}.... inside of onPause(). I should try requestImage() with System.Exit(0) and report back.

onPause() {
System.Exit(0);
super.onPause();
}
