Android Wear: How to go back to home screen after Noitifcation Action press (without canceling notification) -

my intent action press gets service, calling when i'm done service:

            intent startmain = new intent(intent.action_main);             startmain.addcategory(intent.category_home);             startmain.setflags(intent.flag_activity_new_task);             startactivity(startmain); 

yet screen remains on action button.
