Design Android consists of a kernel based on

the Linux kernel 2.6and Linux Kernel 3.x (Android 4.0 onwards), with middleware, libraries and APIs written in C andapplication softwarerunning on an application frameworkwhich includes Java-compatible libraries based on Apache Harmony.

• Multi-touch Android has native support for multi-touch which was

initially made available in handsets such as the HTC Hero. The feature was originally disabled at the kernel level (possibly to avoid infringing Apple's patents on touch-screen technology at the time

handsets have a customized version of the operating system that supports it, either via the UMTS network (like the Samsung Galaxy S) or over IP.
