Yes, sure. So in prototyping, basically to explain the whole Android application framework, start with Linux kernel, where we will be having the Wi-Fi driver, display driver, audio driver, USB driver. Proceeding ahead, we will have platform libraries where instances such as media, OpenGL, graphics, SSL, SQLite and free type of elements will be available in that layer of architecture. And further thereafter, we have Android runtime, that is what consists of post that will be having Android framework. What is the application layer? We will be having the home screen, context, camera, gallery and clock and calendar. Such instances will be having there in my current project. That's how we have managed.
