C++ 调用 Java 返回String类型

java代码

private static String getString(){

return   string;

}

C++代码

static string getDeviceModelJNI() {
        string retValue = "";
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
        JniMethodInfo minfo;//定义Jni函数信息结构体
        jstring jobj;
        bool isHave = JniHelper::getStaticMethodInfo(minfo,"com/wangniu/hlddz/SGddzActivity","getDeviceModel", "()Ljava/lang/String;");
        if (isHave) {
            jobj = (jstring)minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);
        }
        retValue = JniHelper::jstring2string(jobj);
#elif (CC_TARGET_PLATFORM == CC_PLATFORM_MAC)
        retValue = "MAC";
#elif (CC_TARGET_PLATFORM == CC_PLATFORM_WIN32)
        retValue = "Win32";
#endif
        return retValue;
    }
};
