鸿蒙开发Ability Kit程序框架服务：FA模型绑定Stage模型ServiceExtensionAbility

FA模型绑定Stage模型ServiceExtensionAbility

本文介绍FA模型的三种应用组件如何绑定Stage模型的ServiceExtensionAbility组件。
开发前请熟悉鸿蒙开发指导文档 ：[gitee.com/li-shizhen-skin/harmony-os/blob/master/README.md]

PageAbility关联访问ServiceExtensionAbility

PageAbility关联访问ServiceExtensionAbility和PageAbility关联访问ServiceAbility的方式完全相同。

    // ...

ServiceAbility/DataAbility关联访问ServiceExtensionAbility

ServiceAbility/DataAbility关联访问ServiceExtensionAbility和ServiceAbility/DataAbility关联访问ServiceAbility的方式完全相同。
