but they are not run within a Java ME (Mobile Edition) VM, and Java-compiled classes and
executables will not run natively in Android.
Part of the Linux Phone Standards Forum (LiPS) or the Open Mobile Alliance (OMA) —
Android runs on an open-source Linux kernel, but, while their goals are similar, Android’s
complete software stack approach goes further than the focus of these standards-defining
Simply an application layer (such as UIQ or S60) — Although Android does include an application
layer, “Android’’ also describes the entire software stack, encompassing the underlying
operating system, the API libraries, and the applications themselves.

many alternative hardware devices.
Google’s answer to the iPhone — The iPhone is a fully proprietary hardware and software

Most of the applications we create in Android will fall into one of the following categories:

Background Application — These type of application only works at background of phone software. It does not show their visibility, most of its lifetime hidden like alarm clock.
Intermittent Applications — It works at both foreground and background. This type of application do most of their work in the background. Most well-designed applications fall into this category. A common example would be a media player.
Widgets and Live Wallpapers Apps — Some applications are represented only as a home-screen
Widget or as a Live Wallpaper.
