why adb server is out of date. killing... on command prompt?

I have updated android sdk upto for Android 2.2 api level 8. After that I was trying to install apk through adb shell as "adb install" but it was not installing and displays "adb server is out of date. killing..." when I did "adb devices" it was not showing devices. why is that. Please let me know.

Thanks, 开发者_开发问答Vishakha.

After adb is killed, did you run 'adb start-server'?

I faced the same issue when I tried to launch my first app today. And I found the solution. By the way, I was using Windows7. But I think on Linux, the issue may be similar.

1. found the port that adb required is 5037 D:\Installs\adt\sdk\platform-tools>adb nodaemon server cannot bind 'tcp:5037'

2. check which process in on 5037
   D:\Installs\adt\sdk\platform-tools>netstat -ano|findstr "5037" TCP 127.0.0.1:5037 0.0.0.0:0 LISTENING 3908 TCP 127.0.0.1:5037 127.0.0.1:54530 ESTABLISHED 3908 TCP 127.0.0.1:54530 127.0.0.1:5037 ESTABLISHED 10728

3. kill the process 3908

Then start your adb. it should work for you now.

I also had this problem today, turns out I disabled my network drivers because I had WIFI/LAN issues. re-enabling fixed the issue

I have heard of a number of things required to fix this, mainly involving ensuring you do not have conflicting adb.exe files linked in your PATH variable.

The issue with mine is that I am using Genymotion and it was not configured to use the SDK previously installed on my machine. How to fix this can be seen here.

If you are using HTC Sync or another custom backup application that may contain adb.exe, you can try this tool: ADBFix

Once you have made your changes kill the process running port 5037 as specified by Dan. For me the process was AndroidInterface.exe. Then navigate to the platform-tools folder of the SDK and run adb start-server to restart adb.

Just uninstall the SDK-Tools and reinstall. All good!
