- Currently, a new callback is created when a listener is passed in, so it is possible to create multiple callbacks for the same listener - However, when removing the listener, only the latest entry is removed, which could result in improper cleanup - If a listener is already in the map, do not add the listener with the new callback Change-Id: I46f344eb55db38916224f7765cd838347ac8f0f2 Bug: 168886894
