Answer 1

 ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
 // Return a list of the tasks that are currently running,
 // with the most recent being first and older ones after in order.
 // Taken 1 inside getRunningTasks method means want to take only
 // top activity from stack and forgot the olders.
 List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);

 ComponentName componentInfo = taskInfo.get(0).topActivity;
 componentInfo.getPackageName(); // here it is
