Android development is commonly done using Android Studio or some other IDE environment. This short tutorial takes a different perspective of Android programming, and discusses ways in which developing, compiling, installing and debugging Android applications can be achieved on the command line.

The Jkop framework includes a number of widgets, which are reusable user interface components that can be used to construct good-looking, modern user interfaces for mobile devices as well as web and desktop applications. The Jkop Widget API offers a common development framework regardless of the underlying platform, but would use the underlying platform-specific mechanisms to provide the actual functionality.

In this tutorial, we will learn how to develop a simple cross platform mobile application using Sling and SQLite as database.
