Its Anatomy and Features:
Google Android created a storm in the mobile operating system arena even before any mobile manufacturer started shipping mobile phones based on Android. The first question that creeps into our thought is what is android all about and how is it different from the rest?
Well, it goes like this,
Android is the first truly open source comprehensive platform for mobile phones, in simple words is a software stack for mobile devices that includes an operating system, user interface and key applications. Though the key players of mobile operating systems like Symbian, Microsoft windows CE, Apple are already established in this field, Google has tried to make its presence felt by giving many firsts with Android to developers.
In all, the Android is a complete set of software that is needed to run mobile phone without having any proprietary impediment from the manufacturer. Android will provide an open mobile software platform that enables creation of applications that would run and give same user experience on any Android based phone. This hasn’t been the case till now because developers had to refer to the manufacturer’s phones specifications before developing the mobile applications for it. So with Android, if the developer has an idea of app for mobiles he won’t have to go into mobile phone’s specifications but rather develop the app and have it deployed on Android-based handset irrespective of its manufacturer.
How the applications are developed for Android?
The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.
