setDisplay(null) to get midlet to run in background, why?

AtariPete · ‎08-21-2008

Overview

To properly run my midlet in the background on pausApp, I need always setDisplay to null. The code looks like this:

Display display = Display.getDisplay(this);
display.setCurrent(null);

If i do not set display to null, then the background thread of my application doesn't seem to run (the application really does pause).

Question

So this solution works great, but I'm curious to know why it works? Why must I set display to null for the application's background thread to run on pauseApp?

MIDlets do not support background processing. So it should be expected that a MIDlet is paused when it is not in the foreground.
