平常我们使用命令行调用adb去获取信息或者是与手机通讯，了解过adb源码的都清除，在pc端的adb是有adb client和adb service两部分的，正常我们调用的都是adb的client，adb client自己内部会去查询adb service是否已经启动，如果没有就会去启动adb service，再利用socket去通讯，正常我们在代码里面需要利用管道去获取cmd里面adb返回的结果。

       本文就是在我们自己的代码里面直接利用socket与adb service通讯，绕过执行cmd和利用管道获取数据，这种方式在速度上面会快很多，基本原理就是参考adb的源码 把socket与adb service相关的代码移植到自己的工程里面，下面就是一个demo代码，真正移植到项目还需要修改。

(由于在公司有加密软件的原因，源代码只能以文本方式一部分一部分拷贝到博客，所有下面的布局会不清晰)

下面是测试代码，测试代码只是测试了两个命令，测试代码很简单

 AdbSocketHelper adbHelper;
adbHelper.setAdbPathAndPort(L"E:\\work\\adb\\LibAdb\\Debug\\Adb.exe",5037);
string strRet;

strRet = adbHelper.getAdbVersion();
printf("%s\n",strRet.c_str());
strRet = adbHelper.getDevices();
printf("%s\n",strRet.c_str());
strRet = adbHelper.adbShell("dumpsys iphonesubinfo","");
printf("%s\n",strRet.c_str());

简单的把手机连接到电脑，安装好驱动，就能获取到adb的版本信息和当前的设备列表。

其他的adb命令可以参考adb的源码来完善，这里只是给出一个demo，需要在项目中使用的时候，直接把上面的类添加到工程，补充其他的adb命令即可。
