[Android] The connection to adb is down, and a severe error has occured

一.ADB server didn't ACK

在配置完Android环境后,运行第一个程序时,遇到了如下错误：

ADB server didn't ACK

* failed to start daemon *

它可能的原因是端口5037被占用,需要查找占用5037（Android默认）端口的PID,在cmd中输入：

netstat -ano | findstr "5037"

输出进程：

TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 9292

TCP 127.0.0.1:5037 127.0.0.1:49422 ESTABLISHED 9292

TCP 127.0.0.1:49422 127.0.0.1:5037 ESTABLISHED 3840

此时把该进程“9292”结束,代码如下：

TASKLIST | findstr "9292"

二.The connection
to adb is down, and a severe error has occured

在执行上面的结果后可能还会遇到一个错误,经常出现的错误：

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:\..\platform-tools\adb.exe' and can be executed.

如下图所示：



解决方法是在cmd中调用adb kill-server,再调用adb start-server开启服务.但是可能会出现错误：

adb server is out of date. killing...

ADB server didn't ACK

* failed to start daemon *



这是因为端口号被占用,查看豌豆荚或手机助手占用端口号,将kadb\qadb进程关闭.

具体方法如下：

1.先将Eclipse和豌豆荚关掉,同时结束进程kadb.



2.使用cd去到platform-tools文件夹下(含有adb.exe),并开启adb服务如我的指令是：


G:

cd G:\software\Program software\Android\adt-bundle-windows-x86_64-20140321\sdk\platform-tools

adb start-server

成功时输出：

* daemon not running.Starting it now on port 11888*

* daemon started successfully *



最后点击platform-tools文件夹中adb.exe应用程序,再运行程序即可.

注意上面的程序上面的程序输出端口号为11888,如果你的还是不成功,可以修改环境的端口号,如下：



修改端口号再按上面的步骤实现即可.这是配置Android+Eclipse的错误解决方案,希望对你有用~
