1、查看adb 的进程端口号是什么，输入命令 adb nodaemon server 显示端口号

android ActivityManager 端口号获取pid 安卓查看端口号_sed

2、查看端口号对应的进程pid ,输入命令 netstat -ano  查看对应的端口号的进程号

3、查看进程号对应的进程名称或结束进程 tasklist|findstr "进程号"或 taskkill /f /pid 进程号

或者彻底删除这个驱动程序 在任务管理中找到tadb 那个进程程序右击找到它所在的文件夹，直接删除即可！



另一种方法：

自己配置 adb server 端口，使用一个生僻的值。

很简单，只要在系统环境变量中定义 ANDROID_ADB_SERVER_PORT 的值即可。

最好选择一个5位数的端口号（10000 ~ 65535），不易重复。

win下只要在环境变量中增加一个ANDROID_ADB_SERVER_PORT ，值填你自己定义的端口。

linux下只要 export $ANDROID_ADB_SERVER_PORT = 自定义端口，即可。

这时打开一个命令行，输入adb devices，看看是不是在新的端口上启动了啊？ 





以下都是ADB连接问题，可以通过尝试如下步骤，由简单度排序


1. 插拔下USB连接线


2. 关闭USB模式再打开


3. 执行以下命令 



    1. adb kill-server  
2. adb start-server




    4.  效果与3相同



    DDMS - Devices - Reset adb




    5. 关闭所有PC套件，例如：



    杀死 Wandoujia  相关的所有进程，ok



    wandoujia_daemon.exe



    wandoujia_helper.exe



    8. 查看下USB先是否连接电脑与手机


    9. 重启手机


    10. 关闭占用5037端口软件


    11. 更新adb （见问题14）



    1. 查看占用端口5037的PID值 netstat -a -n -o |findstr "5037" 输出结果：  TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       5096  TCP    127.0.0.1:5037         127.0.0.1:51577        ESTABLISHED     5096  TCP    127.0.0.1:51577        127.0.0.1:5037         ESTABLISHED     43242. 从上面得知PID = 5096占用了5037端口，现在通过PID查看进程名，看到底哪个进程占用此端口 tasklist /v | findstr 5096 输出结果：tadb.exe  5096 Console  1  4,932 K Unknown  ......  0:00:02 暂缺网上查询得知tadb.exe是腾讯管家启动的进程3. 杀死占用5037端口的进程 tadb.exetaskkill /f -pid 5096taskkill /im tadb.exe输出结果成功: 已终止 PID 为 5096 的进程。




    问题1  



    1. The connection to adb is down, and a severe error has occured.  
2. You must restart adb and Eclipse.  
3. Please ensure that adb is correctly located at 'adb.exe' and can be executed.


    问题2 



    1. ADB server didn't ACK  
2. * failed to start daemon *



    问题3 





      1. Adb failed to restart！ Make sure the plugin is properly configured
