How to test my intent handle logic inside my android application

My application is used to provide the functionality to our client(application) to access the remote device by using intent, the API logic is quite simple as client send the intent to our application and wait for the response by listening to the intent for result.

I am looking for a test framework can be used for my verification purpose, there are many service and thread inside each intent handle so it is not very easy to write unit test, instead i wander if i can use more general test framework to test the api only.

Any kindly advise is welcome.
