Up until now, there hasn’t been a documentation of the Tizen Wearable OS platform which runs on gear 2 devices.

Gear Widget Settings
If you wish to use Gear Manager to manage the configuration of your wearable-side application, include a settings.xml file in the settings folder in the wearable-side widget.

The XML settings file uses a String ID format to support multiple languages. To support multi languages for your application, add the required strings in all the supported languages. The file name must be settings.xml. The idea is that after you add settings.xml to your gear app, it generates the settings on gear manager when the widget is installed.
Here’s what the settings could look like in Gear manager settings.

Here are the settings which the notification intent can take
