Android – A Revolutionary Mobile OS

This is an era of smartphones. People have access to 3G, 4G technologies. Most of the things we can do online can be done on mobile phones whether it is to transfer money, pay bills or shopping. Mobile handset is no more a device just used for communication. This serves as an entertainment system. We can watch videos, movies, listen to music, play games, and access web applications on a mobile handset.

All these things are achieved by developing various applications which run on a particular mobile operating system. Android is a most popular open source Mobile OS used in smart phones.
