This is what I have done.

Inside op control:

if(INSERT SOMETHING HERE) {

new Thread() {
     public void run() {
          //Code to run here:
          Thread.sleep(time in ms);
          //More code
          }.start()
     }
}

What this does is every time the if statement becomes true it creates a thread and runs the code in run() {} then kills the thread. you can use Thread.sleep(); inside this and it will NOT affect your main code only whats in that thread.

This has worked well for me.

Hope this helps!
