What is “Android”

“Android is a software stack for mobile

devices that includes an operating system,

middleware and key applications. The Android

SDK provides the tools and APIs necessary

to begin developing applications on the

Android platform using the Java programming

language.”

http://developer.android.com/guide/basics/what-is-android.html

Geekic Overlook

Although the Java syntax is used

and Java bytecode serves as an

input for creating an Android application,

the actual runtime environment is the

Dalvik VM which does not support all the

standard Java behaviors or libraries (like

Swing)

●

Geek points: Standard JVMs use a stack,

the Delvik VM is register-based
