Greetings, Dianne, Yi and others, I have a need to do something similar, that is to access a backend native service from the application.
Going through the messages here, there are several things that are unclear to me. I'd really appreciate if you can provide more information on them. (1) On the native service side (C/C++), I can create a native binder service class. I can also implement a native executable to instantiate the binder service and add the service to the service manager. Then what is the right way to start the native service? (Run the native executable in some start up scripts?) (2) On the application side (Java), Dianne, you mentioned "make a shared library that apps request with <uses-library>", exactly what is this shared library? Is it the native shared library containing the interface implementation of the service?
