I was able to fix the problem. The issue was that i did not have the context instance in my callback class.
I created a constructor where I got the context from the service class. Using that I was able to call the application activity class. Also I had to use myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); for starting the task.. This was my constructor in the callback class private VServiceCallBack(Context iContext) { context = iContext; } And according to the arguments received, { Intent appView = new Intent(context, AppView.class); appView .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(appView ); } Sorry for the confusion, and thanks for the help..
