Hi Natalie - Not sure what you mean by service you "spawned onto its own thread".
In any case, it looks like the Service is going to be pretty busy in that while(1) loop so it is not too surprising that it is not available to process the showMessage call. :) Yes they are two different threads. The Activity is blocking on the call to the service that is forever busy in the for loop. I think you need to put that loop in a thread and then you need a different Runnable for the handler post(). Here is an example - http://developer.android.com/resources/faq/commontasks.html#threading Also the serviceHandler.post(myProcess) in onCreate is a duplicate. This is where you need something like startLongWhileLoop() that creates a thread instead.
