ADB server didn’t ACK 这个问题会困恼很多的新手朋友,我以前刚开始做Android的时候也遇到过这个问题,不过自己百度,google啥的,也不知道怎么就给解决了,看到群里很多新手朋友都会问这个问题,说实话我也没有一个解决这个问题的终极方法(百试百灵的那种,哈哈),自己没遇到也没有认真的去对待他,今天,就是在今天,我打开Eclipse连上手机,准备调试程序,出现如下的信息
The connection to adb is down, and a severe error has occured.
You must restart adb and Eclipse.
Please ensure that adb is correctly located at ‘D:\android-2.2-windows\platform-tools\adb.exe’and can be executed.
