Now, Your Friends Are Alarmed

String parameter that is the "name" of the service. What role this name

plays is unclear. So, add a functional constructor:

public PostMonitor() {

super("PostMonitor");

}

Now you can get rid of the isActive and threadBody data members, along

with all references to them (which you will find in onCreate() and

onDestroy()).

Now, if you rebuild and reinstall the project, Patchy should work as before.

The exception is that if you have Patchy on a device, and you let the device

fall asleep while Patchy is still active, you should still receive status updates.

Here is the entire listing of PostMonitor after all of these changes:
