1.Android uses the dalvik a similar java jre specially made for android. 90-95% of the code is same in java and android, and in the starting the cross platform java applications on other platforms were easily converted to android, around 50000 java applications were converted without much change in code.Also android had access to almost a million java mobile coders in the starting.
2. Android is based on Linux one of the most secure Operation systems of the world,therefore android was virtually virus free for almost first 18-24 months of its run , this made it stable and made consumers happy.
3. Android was one of the first os that fully supported touch screens as must as apple ios. No other os like symbian, blackberry was even close in supporting the touch screen interface. So it became the lone competitor of apple.
4. Android is free to use even by manufacturers,companies like Samsung,lg,htc were finding an OS that could meet their requirement and make people love it just like apple, android made this possible,Symbian belonged to Nokia,blackberry to rim,i OS to apple, these companies had to launch phones on slow java technology that didn't helped them, so android solved these problems.Android also had free Google services so people found this platform user friendly and most programmers or java world just switched to android world and android started the touch screen non apple movement of the world.
