Adb server not responding [duplicate]

Answer 1

根本原因是因为你的机器上5037端口被某个进程占用了，此时不但android设备无法使用adb连接，ios设备也不能用iTunes连接。

可以查询到占用5037端口的进程并关闭它，netstat /a /o 也许可以帮助你。

要windows7上，LogsAndAlerts服务会占用5037端口。

---

The fundamental reason is because the 5037 port on your machine to be occupied by a process, not only Android devices can not use adb connection ios device not use iTunes.

Can query process and close it, netstat / a / o maybe can help you to take up to 5037 ports.

To windows7 the LogsAndAlerts service will occupy port 5037.

Seems like the security program is blocking adb.exe, so go to the adb file path and open adb's properties, then check the Run this program as administrator setting.

Answer 3

I suspect the problem is cause of many adb instances (in windows) , i usually face this problem cause i don't turn off my system so the adb process may not end properly.

So open task manager choose Process tab just search for adb.exe, right click on it and choose End Process Tree rather than just End Process

Answer 4

Had the same problem, it seems that my security solution was blocking adb.exe

Answer 5

This will occur normally,if abd is not able to launch properly and didn't exit when adb kill-server is executed.

So if in Windows 1. Go to Task Manager (CTRL+ALT+DEL) 2.look for adb.exe and end the process. Now restart the emulator ,should work properly.

additionally you can close and launch the development environment also (eg: Eclipse or NetBeans).

I found there was a process call "Tadb.exe" in Windows Task Manager. I guess Tadb.exe is a similiar adb application of Tencent. Because I got an alert of "android device detected by QQ" after I install the last version of Tencent QQ2013 Beta5 (6970) yesterday.

After I killed the Tadb.exe, the original adb.exe of Android SDK works again.

You can see the detailed proecss to solve this problem here: adb cannot run, adb server is out of date
