Android is the most important OS & platform in the world. Five years ago, when Android was introduced, it was met with wide skepticism and little enthusiasm by many pundits and experts. It delivered on that skepticism with a lackluster initial commercial launch. But today, Android is the dominant mobile operating system – preloaded on 70% of Smartphone’s shipped worldwide in 2012 – and it is now poised to be the OS that runs the world.


Android is the mobile operating system developed by Google. Android is a Linux-based software system, and similar to Linux, is free and open source software. This means that other companies can use the Android operating system developed by Google and use it in their mobile devices (more on that later). The distinguishing factor of this brand is a kernel. Android hosts a central core, which essentially is a strip code that helps the software operate. Android has the largest installed base of all operating systems of any kind. Android has been the best selling OS on tablets since 2013, and on Smartphone’s it is dominant by any metric. Google produces the software that runs almost every other mobile phone besides Apple’s I Phone.


Currently Google is working hard on Android OS. Google is going to make it more secure in very new version, which leads it to have more shares in market. Android is most growing mobile OS in the market. Google is also working on Android Studio very fast and try to solve the developer’s problem.
Being an open source platform, I don’t see an expiry date for Android. It is being used in almost every smart device out there. It is not only famous, but extremely desirable not only for the users but also the developers. ART runtime is the future of Android. Keeping in mind that there are companies that customize the stock Android and add their own modifications suiting them, more and more companies are adopting this. Since it is an open source OS, developers can create their own custom ROMs, suiting their needs and also make it available for users. This will only lead to one conclusion, the future of Android is just going to get wider. Not only in mobile phones, but also tablets and even PCs have this operating system.
