+# @ohos.application.StaticSubscriberExtensionContext (StaticSubscriberExtensionContext)
+
+StaticSubscriberExtensionContext模块是StaticSubscriberExtensionAbility的上下文环境，继承自ExtensionContext。
+
+StaticSubscriberExtensionContext模块提供StaticSubscriberExtensionAbility具有的接口和能力。
+
+> **说明：**
+>
+> 本模块首批接口从API version 10开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
+> 本模块接口仅可在Stage模型下使用。
+
+## 使用说明
+
+在使用StaticSubscriberExtensionContext的功能前，需要通过StaticSubscriberExtensionAbility获取。
+
+```ts
+import StaticSubscriberExtensionAbility from '@ohos.application.StaticSubscriberExtensionAbility'
+
+export default class MyStaticSubscriberExtensionAbility extends StaticSubscriberExtensionAbility {
+    context = this.context;
+};
+```
+
+## StaticSubscriberExtensionContext.startAbility
+
+startAbility(want: Want, callback: AsyncCallback<void>): void;
+
+启动Ability（callback形式）。
+
+使用规则：
+ - 调用方应用位于后台时，使用该接口启动Ability需申请`ohos.permission.START_ABILITIES_FROM_BACKGROUND`权限
+ - 跨应用场景下，目标Ability的visible属性若配置为false，调用方应用需申请`ohos.permission.START_INVISIBLE_ABILITY`权限
+ - 组件启动规则详见：[组件启动规则（Stage模型）](../../application-models/component-startup-rules.md)
+
+**系统能力**：SystemCapability.Ability.AbilityRuntime.Core
+
+**系统API**：该接口为系统接口，三方应用不支持调用。
+
+**参数：**
