android安卓月光宝盒项目源码技术讲解
2024-05-11 12:30:35
月光宝盒游戏机大家都了解，但是里面开发流程指导的人比较少，去年本人有幸接到过这样一个项目，研发月光宝盒游戏机。 在过去几年这边积累了非常多的模拟器开发资源。下面是淘宝上一款月光宝盒机器，实际上目前有几个大厂在做，淘宝上爆款一看就了解，我的客户机器比这个还要大一些，需要投币。
可以在网盘下载，app体验：https://pan.baidu.com/s/1c2BdnPY
软件分为2个部分：输入装置+游戏机APP+输出装置。这样就组成一个游戏机系统。
输入装置: 这里主要是按键摇杆， 客户的按键是通过串口实现的，需要我自己去读串口发到我的APP中。
而且客户为了怕设备被破解，串口通信还加了密，真是坑爹啊。
游戏机APP：这里使用的是我 这边街机pro专业版游戏机模拟器，支持拳皇97 98等8000多个游戏。 通过修改，去掉游戏机里面触摸按键，介入上面说的游戏按键。
输出装置：输出装置就是显示器和声音。这些都是走的安卓系统通用api。不需要特殊处理。
这里先贴出串口处理的部分代码：，一般来说摇杆按键走的串口，一般需要经过加密，不然太容易破解了：别人可能盗走你的游戏主板去硬件山寨出一个跟你一模一样的东西。所以这就要涉及加密了。

#define IsLock 1//下函数由叶先生实现/*需要在JNI中实现如下函数功能函数函数功能：将OStar_msg结构加密后转化成字节。
函数目的：（用于java层调用后获得返回字节结果，java层将直接写入到串口。）
char * MsgToByte(OStar_msg msg)函数功能：将字节添加到缓冲区。 若成功返回1，若缓冲区满返回0
函数目的：（用于java层从串口获得字节后调用它将字节保存到缓冲区）
int MsgCacheOffer(char * byte)函数功能：将从缓冲区取出24个有效数据返回，若无返回NULL。（函数需要校验 直到成功取出正确数据）
函数目的：（用于java层调用后，直接从串口取出正确数据）
OStar_msg MsgPoll()*///下函数由softboy实现/*
需要在JNI中实现 Java 层接口函数：函数功能：将java层函数数据转化成 OStar_msg
函数目的：调用MsgToByte转成成字节返回给java。用于发送。调用 MsgToByte（）；
