We need to navigate between Captivate courses loaded to a Mobile Device with no browser.

We are building training courses to support a business application that will run a specialized Android devices that are locked down to run one specific business application. The devices will not include a browser. We are loading the individual courses as APKs. We need a method of navigating between the courses without a browser. Can we build one course that serves as the navigation and calls the other courses? Can we get to each individual course and then back to the menu? We also need to get from the courses back to the original business application. Again, the devices is locked down and users will not have access to a browser or the standard Android desktop. Our developers can build something in javascript or the Android "Intent" language, if necessary. But it would help to have some consultation from a Captivate developer who knows how the Captivate courses are compiled for mobile devices.
