How to access the Common API files?
Common Modules usage guidelines
The Common Modules application files like Widget.js or TVKeyValue.js are installed on each SmartTv device in the $MANAGER_WIDGET directory. It is not recommended to copy these files to your application package. Each device has its own version of the common files and they are accessible by all installed applications.
When you copy the common files from the SDK, they will probably work well on most TV sets, but they could make some problems on BD Players. If you use the common files from $MANAGER_WIDGET path, you may be sure that they are always up-to-date with your firmware and compatible with all the devices.
