    • Why Android OS? • Why is Android the popular choice? • Android’s popularity as the ideal OS for smart phones is increasing because of one simple reason: No other platform provides as many applications for free! • No doubt, the market is flooded with jobs in field of application development in iOS, Blackberry, Symbian and other platforms as well, but the open-source nature of Android definitely adds to its appeal. • It is because of this kind of consumer demand that so many tech firms are actively seeking talented Android developers. Consumer today knows his/her requirements, and wants a handy application to take care of it.
