Power of Android

Was studying about android, as its being famous in mobile technology these days. Here is summery of my first research.

What is Android?
Android is nothing but a software platform for mobile devices which are based on most flexible operating system i.e. Linux. Android is developed by Open Handset Alliance and acquired by Google. Android is a software stack for mobile devices that includes an operating system, middleware and key applications.

Android Development
Android applications are written in the Java programming language. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java.

An Android package archive file marked by an .apk suffix. This file is used for distribution and installation of the application on the mobile device.

Power of Android application.

• Phone's core applications and third-party applications are treated equally.
• Android actually breaks down all the barriers of application development by providing lots of libraries and tools. e.g Android enables developers to obtain the location of the device.
• By default, every Android application runs in its own Linux process.
• Every application has its own virtual machine. So the app runs in isolation from other apps.
• Each application is assigned a unique Linux user ID which is set with some permissions required by the perticular application only. Where as it is also possible that two or more android application share a same user id in some cases.
