          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();

      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: ' + error.code +
          ' error.message: ' + error.message);
