+## cl.ability.6 Caller相关接口变更
+Caller相关接口使用RPC废弃的Sequenceable和MessageParcel对象，使用RPC在API9提供的Parcelable和MessageSequence对象替代。
+
+**变更影响**
+
+影响API9版本的JS接口，应用需要进行适配才可以在新版本SDK环境正常实现功能。
+
+**关键的接口/组件变更**
+
+| 模块名                    | 类名                | 方法/属性/枚举/常量                                          | 变更类型 |
+| ------------------------- | ------------------- | ------------------------------------------------------------ | -------- |
+| api/@ohos.app.ability.UIAbility.d.ts | CalleeCallback | (indata: rpc.MessageParcel): rpc.Sequenceable; | 变更，修改为 (indata: rpc.MessageSequence): rpc.Parcelable;     |
+| api/@ohos.app.ability.UIAbility.d.ts | Caller | call(method: string, data: rpc.Sequenceable): Promise<void>; | 变更，修改为 call(method: string, data: rpc.Parcelable): Promise<void>;     |
+| api/@ohos.app.ability.UIAbility.d.ts | Caller | callWithResult(method: string, data: rpc.Sequenceable): Promise<rpc.MessageParcel>; | 变更，修改为 callWithResult(method: string, data: rpc.Parcelable): Promise<rpc.MessageSequence>;     |
+
+**适配指导**
+
+应用中调用Caller相关接口可参考下列代码
+
+变更前代码：
+
+```ts
+  class MyMessageAble{
+      name:""
+      str:""
+      num: 1
+      constructor(name, str) {
+        this.name = name;
+        this.str = str;
+      }
+      marshalling(messageParcel) {
+          messageParcel.writeInt(this.num);
+          messageParcel.writeString(this.str);
+          console.log('MyMessageAble marshalling num[' + this.num + '] str[' + this.str + ']');
+          return true;
+      }
+      unmarshalling(messageParcel) {
+          this.num = messageParcel.readInt();
+          this.str = messageParcel.readString();
+          console.log('MyMessageAble unmarshalling num[' + this.num + '] str[' + this.str + ']');
+          return true;
+      }
+  };
+  let method = 'call_Function';
+  function funcCallBack(pdata) {
+      console.log('Callee funcCallBack is called ' + pdata);
+      let msg = new MyMessageAble("test", "");
+      pdata.readSequenceable(msg);
+      return new MyMessageAble("test1", "Callee test");
+  }
+  export default class MainUIAbility extends UIAbility {
+    onCreate(want, launchParam) {
+      console.log('Callee onCreate is called');
+      try {
+        this.callee.on(method, funcCallBack);
+      } catch (error) {
+        console.log('Callee.on catch error, error.code: ' + JSON.stringify(error.code) +
+          ' error.message: ' + JSON.stringify(error.message));
+      }
+    }
+  }
+```
+
+变更后代码：
+
+```ts
+  class MyMessageAble{
+      name:""
+      str:""
+      num: 1
+      constructor(name, str) {
+        this.name = name;
+        this.str = str;
+      }
+      marshalling(messageSequence) {
+          messageSequence.writeInt(this.num);
+          messageSequence.writeString(this.str);
+          console.log('MyMessageAble marshalling num[' + this.num + '] str[' + this.str + ']');
+          return true;
+      }
+      unmarshalling(messageSequence) {
+          this.num = messageSequence.readInt();
+          this.str = messageSequence.readString();
+          console.log('MyMessageAble unmarshalling num[' + this.num + '] str[' + this.str + ']');
+          return true;
+      }
+  };
+  let method = 'call_Function';
+  function funcCallBack(pdata) {
+      console.log('Callee funcCallBack is called ' + pdata);
+      let msg = new MyMessageAble("test", "");
+      pdata.readParcelable(msg);
+      return new MyMessageAble("test1", "Callee test");
+  }
+  export default class MainUIAbility extends UIAbility {
+    onCreate(want, launchParam) {
+      console.log('Callee onCreate is called');
+      try {
+        this.callee.on(method, funcCallBack);
+      } catch (error) {
+        console.log('Callee.on catch error, error.code: ' + JSON.stringify(error.code) +
+          ' error.message: ' + JSON.stringify(error.message));
+      }
+    }
+  }
+```
