+The `proxy` parameter we set in the `registerModuleAppActivities` method above is the default global proxy `Activity`.
+
+If you need to specify a delegated `Activity` to use another Host App's `Activity` as a proxy, you can refer to the following method.
+
+> The following example
+
+```kotlin
+class HostTestActivity : ModuleAppActivity() {
+
+    // Specify an additional proxy Activity class name
+    // Which must also exist in the Host App's AndroidManifest
+    override val proxyClassName get() = "com.demo.test.activity.OtherActivity"
+
+    override fun onCreate(savedInstanceState: Bundle?) {
+        super.onCreate(savedInstanceState)
+        // Module App's Resources have been injected automatically
+        // You can directly use xml to load the layout
+        setContentView(R. layout. activity_main)
+    }
+}
+```

+上面我们在 `registerModuleAppActivities` 方法中设置的 `proxy` 参数为默认的全局代理 `Activity`。
+
+如果你需要指定某个代理的 `Activity` 使用另外的宿主 `Activity` 进行代理，你可以参考如下方法。
+
+> 示例如下
+
+```kotlin
+class HostTestActivity : ModuleAppActivity() {
+
+    // 指定一个另外的代理 Activity 类名，其也必须存在于宿主的 AndroidManifest 中
+    override val proxyClassName get() = "com.demo.test.activity.OtherActivity"
+
+    override fun onCreate(savedInstanceState: Bundle?) {
+        super.onCreate(savedInstanceState)
+        // 模块资源已被自动注入，可以直接使用 xml 装载布局
+        setContentView(R.layout.activity_main)
+    }
+}
+```
