and second activity plays the media, when i hit play button there, acoording to the button click,
if i click on button1, song1 starts, button 2 plays song2 like dis,
my 2nd activity also contains 1 back button,
now the problem is,
when i hit button1, song1 gets start playing....so far its fine
now when i hit back button, song stops and i got activity 1...
so far its fine
