Description
Right now the way the Activity and Service classes stop python is to kill the whole process. That's a very heavy handed way to stop the python thread since it prevents the application taking any action when it has to stop.
I think an one way to do this would be to define a custom python exception and raise it in the python interpreter. The application could catch the exception, perform any actions it needs, and then return gracefully. From the Java side, it would run this via the JNI from a different thread than python is running in. In that case, I believe you could use one of these two mechanisms to raise the exception in the python main thread.
