Basically. You'll want to manage messages -- you don't want to stack up multiple DO_WIFI_SCAN messages. If you want to do something every X ms, in your message handling you would post a new message each time with a delay of X. Use Handler.removeMessages() to ensure that you don't have multiple timing messages active.
This approach is just a basic message loop, so just follow the same approach you'd use on other platforms for message-based code. HandlerThread is just a Thread running its own message loop, so instead of using sleep() to do timing you can do the same delayed message posting.
