android aidl-cpp方式接口调用出现问题

android aidl-cpp方式：

java　client 端调用接口：　return mPoiGateWayService.hasHomeLocation();

C++ service端实现接口：　
Status hasHomeLocation(bool* _aidl_return) override {
ALOGI("Entering hasHomeLocation");
*_aidl_return = true;
return Status::ok();
}

aidl 声明的接口:　　boolean hasHomeLocation();

问题：为啥java端接口调用的时候报错：　　I apkPoiTest: call cns hasHomeLocation fail: java.lang.IllegalArgumentException
