service+ActivityManager....

 

        ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
        List<RunningTaskInfo> TaskList = am.getRunningTasks(2);
        if(TaskList == null || TaskList.isEmpty())
                return;
        
        RunningTaskInfo rti = TaskList.get(0);
   
        String tmp = rti.topActivity.getPackageName();
