同wifi，手机控制电脑以及智能家具实现代码

最近了解谷歌别人写安卓软件操控电脑智能家具等，感觉很有趣就去了解一下，首先拿到软件就是反编译看看里面源代码了解怎么去实现的，本人在校一名大学生技术比较垃圾，大神勿喷(⁎⁍̴̛ᴗ⁍̴̛⁎)！
【软件名称】：WIFI Mouse Pro
【软件大小】：约10MB　
【重要声明】：只供用来学习以及参考　　　　　
【软件下载】： https://aweikejiyuan.lanzous.com/b015guftc?from=singlemessage&isappinstalled=0
【软件功能】：
1.支持语音识别并发送文本到电脑端，支持Android系统键盘的输入
，这个是最牛逼的，再也不要说我打字慢啦！
2. 支持鼠标的光标移动可以调节灵敏度，和鼠标一样具有左键右键以及滚动条
3.支持自动连接电脑端，还可以远程操控把电脑变成横屏竖屏都可
4.支持媒体播放控制，ppt演示控制，电脑放桌子上人在床上不舒服吗
5.支持全屏幕的触摸板，变成游戏机，玩游戏更爽快
6.支持全屏幕的全真实体键盘，敲代码写作业真的舒服
7.支持实体键盘的快捷键和热键软件特色：
8.支持整理电脑中文件以及打开使用
9.具备截屏和关机睡眠注销等控件，真的不要太方便
【支持的手势识别有】
1.单个手指轻触屏幕代表单击
2.单个手指快速单击代表双击
3.两个手指同时向上/向下滑动，代表滚动
4.三个手指移动代表拖拽
5.四个手指向下滑动代表显示桌面
4.三个手指移动代表拖拽
5.四个手指向下滑动代表显示桌面
6.四个手指向上滑动代表当前窗口最大化
7.四个手指左右滑动代表切换应用程序窗口
8.单个手机轻按一小会再移动，代表拖拽
9.两个手指同时单击代表鼠标右键单击
10.两个手指放大和缩小操作，类似手机的图片放大/缩小操作
【安装方法】
把MouseServer.exe在电脑上运行
电脑和手机需要在同一个wifi下才行

上面是主要java代码，实现了能够随机播放音乐，可以用手机关机电脑文件里所有东西，手机变成了键盘以及鼠标，更可怕的是能够做游戏炳
