The Xlet interface is used to prevent application resource conflicts, to stably run an application, and to provide an environment for managing a lifecycle.

An Xlet has four states: "Loaded", "Paused", "Active", and "Destroyed".

After the application download is complete, loading the startup class file to create a new Xlet instance results in a "Loaded" state. After that, the broadcast middleware calls the "initxlet ()" function 301 to initialize the Xlet and enters the "Paused" state. An Xlet in the "Paused" state means a state ready for execution.

Calling the "startXlet ()" function 302 acquires the resource, executes the Xlet, and changes to the "Active" state. A running Xlet may call the "pauseXlet ()" function 304 to release some resources that may cause resource conflicts and change them to the "Paused" state, which in turn causes the "startXlet ()" function 302 to Can be called to obtain resources and resume execution. The Xlet can be terminated at any time by calling the "destroyXlet ()" function 303. When the Xlet is terminated, the Xlet goes to a "Destroyed" state by going through a cleanup process of releasing all resources.
