adb server is out of date. killing...

1:今天调试android的时候发现一个诡异的问题

[html]
view plaincopyprint?

C:\Users\xxxx>adb start-server adb server is out of date. killing... ADB server didn't ACK * failed to start daemon *

C:\Users\xxxx>adb start-server
adb server is out of date.  killing...
ADB server didn't ACK
* failed to start daemon *

adb 不管执行 shell devices 还是logcat 都会报错

[html]
view plaincopyprint?

adb server is out of date. killing...

adb server is out of date.  killing...

究其源就是adb server没启动

到stackoverflow上查了一下 经过分析整理如下：

[html]
view plaincopyprint?

C:\Users\xxxx>adb nodaemon server cannot bind 'tcp:5037'

C:\Users\xxxx>adb nodaemon server
cannot bind 'tcp:5037'

原来adb server 端口绑定失败

继续查看到底是哪个端口给占用了

[html]
view plaincopyprint?

C:\Users\xxxxxx>netstat -ano | findstr "5037" TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 4236 TCP 127.0.0.1:5037 127.0.0.1:49422 ESTABLISHED 4236 TCP 127.0.0.1:49422 127.0.0.1:5037 ESTABLISHED 3840

C:\Users\xxxxxx>netstat -ano | findstr "5037"
TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       4236
TCP    127.0.0.1:5037         127.0.0.1:49422        ESTABLISHED     4236
TCP    127.0.0.1:49422        127.0.0.1:5037         ESTABLISHED     3840

打开任务管理器kill掉4236 这个进程。ok

D:\Android_SDK\platform-tools>adb start-server

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

至此问题解决了
