As the name suggests, middleware is software components that sit in between—in this case between the operating system and the applications/application framework. The middleware includes libraries for many functions (data storage, graphics rendering, web browsing, and so on) and it also contains a special subsection called the Dalvik runtime.

5 More capabilities with native libraries We’re now going to look at the system libraries bundled with the Android platform. Welcome to the world of C/C++ and native libraries! These libraries are also exposed to the Android SDK via JNI, and therefore you don’t have to deal with native code (unless you want to), but it’s important to understand the relationships. Well cover these libraries briefly, to describe the Android middle tier. Our intention is to give you an idea of what’s possible with Android by looking at some of the technologies that ship with it.
