Stopping a service once it has finished it's work

Question

I have an Android Service that is started by my application and does some things in a threadPool using Executors.newCachedThreadPool()

Once it has finished doing it's work I would like the service to stopSelf(), how can I get the service to determine when it is no longer needed (ie, there are no more Threads executing) so that it can shut itself down automatically?

Answer 1

Do it the other way: the last Runnable should shut the Service upon completion.
