Thread Pool
Because the BlackBerry has rather constrained Thread count limitations we use a Thread pool to manage our threads. To run something in the Thread pool use the code: MobileApplication.instance().getApplication().getThreadPool() to get a reference to the application's thread pool and then call invokeLater() with a runnable object to run it in the Thread Pool. Here is a complete example:
MobileApplication.instance().getApplication().getThreadPool().invokeLater( new Runnable() { public void run() { System.out.println("I'm in a Thread Pool."); } } );
This is different from calling Application.invokeLater() since the application invokeLater method runs your code on the event thread which could unnecessarily lock the UI.
