3. kylin-sdk 2.0

Ubuntu Kylin 24.04 version integrates the new kylin-sdk 2.0, allowing developers to more quickly develop applications that adapt to the Ubuntu Kylin system. kylin-sdk 2.0 currently focuses on three major modules, including application support SDK, system capability SDK, and basic development SDK.

  • 01 Application support SDK:In the application support SDK, all packages provide graphical development functions for graphical applications, such as graphical controls, theme styles, etc. This layer is usually bound to a specific development framework, such as QT and GTK.

  • 02 System capability SDK:Each software package in the system capability SDK expresses one or a type of system capability, such as operating system information, hardware management, system security policy, network management, etc.

  • 03 Basic development SDK:The design of this layer mainly provides a set of highly versatile and basic functions that are independent of the operating system for application development, reducing the differences and complexity of different applications implementing the same functionality.
