problems while running an application in background
<p>Hi 
I am developing an android app a musicplayer.It works well except when you hit back key of your phone. It keeps playing song in back ground which is very desirable,but when you open the application again to pause or stop it  does not works . I guess a new instance of the application is created on opening the app again. I dont want to create a new instance i want to open the older one to stop it.I hope i am clear.Is there any way to do this.</p>
