简介
（解释1）ADB的全称为Android Debug Bridge，就是起到调试桥的作用。通过ADB我们可以在Eclipse中方面通过DDMS来调试Android程序，说白了就是debug工具。ADB的工作方式比较特殊，采用监听Socket TCP 5554等端口的方式让IDE和Qemu通讯，默认情况下ADB会daemon相关的网络端口，所以当我们运行Eclipse时ADB进程就会自动运行。
（解释2）ADB是 Android 开发/测试人员不可替代的强大工具，也是 Android 设备玩家的好玩具。
（解释3）Android 调试桥 (adb) 是一种功能多样的命令行工具，可让您与设备进行通信。adb 命令可用于执行各种设备操作（例如安装和调试应用），并提供对 Unix shell（可用来在设备上运行各种命令）的访问权限。
