An Android application is a software application running on the Android platform. The Android platform is a software stack for mobile devices that includes an operating system, middleware and key applications. Android applications are written in Java programming language and run on Dalvik, a custom virtual machine designed for embedded use which runs on top of a Linux kernel. Android applications use the Android API, which is a collection of Java classes, to access core mobile device functionality such as location information, accelerometer data, network connections, and phone calls.
