In the pre and post execute methods, we worry about the Progress Dialog and re-enabling the button. Before loading it to a device, take a closer look at the on Pre Execute method of the Async Task.
The on click view handler is responsible for disabling the button and then spawning a new Async Task that will handle the background work.
