The flexibility of Tizen is not limited to mobile devices but extends to other devices, including the Galaxy Watch. This can be translated to developing applications that can be built using a Native or a Web approach. Whether you are a serious developer or a hobbyist, C or HTML5, building a Tizen app can suit your programming style that can be implemented across platforms.
Follow these contents enabling you to get to know the Galaxy Watch Application Development. Create a HelloWorld sample application to see what Tizen can offer.
The watch face is the main screen that the user will see every time they interact with the Galaxy Watch. This guide is focused on Native development, though, designing the Watch Face can be either be done Native or by Web manually.
Widgets act as display relevant information and actions that are shortcuts to the actual applications. These can be applied onto the Galaxy Watch applications. Widgets for Galaxy Watch are perfect for host applications that can be easily accessed.
Companion-type applications mean an application model that needs data communication or interaction between an Android mobile application and a Galaxy Watch application. The communication protocol between the Galaxy Watch and mobile applications is called Samsung Accessory Protocol (SAP).
Web application is essentially a Web site stored on your device and built using Web-native languages, such as HTML5, CSS, and JavaScript. The Web application uses the Tizen Web Framework to interact with the native subsystems.
Native Application is developed using C and can access more advanced device-specific features, such as sensors, in addition to more advanced system settings and functionality.
Tizen .NET enables you to build .NET applications with Xamarin.Forms and the Tizen .NET framework. Xamarin.Forms allows you to create a user interface.
The following figure illustrates the Tizen architecture model supporting the two application types.
