Android -- How to detect if Monkey Tool has finished working?

I'm developing an application which is basically about performing stress/functional tests for the devices that are being produced.

The application should wait until Monkey Tool finishes working so that it can produce a .log file and inform about the UI test. I have no troubles generally but I need to know if the Monkey Tool has finished the test.

I have checked the main documentation here: Monkey Android Documentation.

Also I had some time to look at Monkey source codes. An example one is: Monkey.java

Unfortunately, I couldn't really find any clue about detecting the moment when monkey finishes working.

So the real question is:

Is there a way to detect or get information when the monkey tool finishes testing the UI?
