Hiya.
That leads to an error: Cannot make a static reference to the non-static 
method getApplicationContext() from the type Context. 
Also, that call would only obtain the application context which is not the 
same as the Application singleton that, for example, you can obtain from an 
Activity via:
MyApp myApp = (MyApp) getApplication();

Well, sure. I was just showing you the class and method you needed.

Yes it is. Try it. I just did.

Oh, yeah sorry about that :D
I hadn't realised that you can use the application context like that.
So, yes in my onPerformSync I am able to do:
FooApp app = (FooApp) getContext().getApplicationContext();
Thanks, I'm still unsure how to acheive what I'm after from here, but it's
a step forward..

A simple static boolean flag should suffice. Each component will run in the
main thread initially to start up. First check the flag, if set, abort the
sync, if not, set it, then proceed with background sync, then reset it when
done.
