ddms: 'adb.exe,start-server' failed -- run manually if necessary, Android Studio

Question

My adb is down, no matter I am using ADT or Android Studio.

And according to the second answer of this SO question, I did:

I type:

adb nodaemon server

Output:

cannot bind 'tcp:5037'

Then netstat -ano | findstr 5037

I did find a pid of 7416 who listen in 127.0.0.1:5037
I use taskkill /pid 7416 -f to kill it.
I type netstat -ano | findstr 5037 again, I found another pid listens at 127.0.0.1:5037 again!

I guess they are the same, but I have no idea who it is.

Can I simply have a easy way to release this port or change the adb port to another one?

Have you tried tasklist|findstr 5037 to find the name of the program at 5037? — Spencer, Oct 03 '14 at 14:37
What program is listening? Is it an adb or something else? If it's a one-time issue rebooting may work, otherwise you may have to figure out what is claiming that port. In theory ADB could be patched to utilize a different one. — Chris Stratton, Oct 03 '14 at 15:51
@ChrisStratton , I found that program!! And I kill it and stop it from booting, which solves this problem now. — JaskeyLam, Oct 03 '14 at 16:16
I'm facing similar kind of issue can any one suggest me why this is happening — Aman Systematix, Feb 16 '17 at 11:29

In my case I was trying to use genymotion emulator device. With genymotion opened and running, I've tried to run my app in this emulator but I it doesn't worth

In this part I had this error:

'C:\Users\Jose\AppData\Local\Android\sdk\platform-tools\adb.exe,start-server' failed -- run manually if necessary

Then I've tried Jaskey's solution but it doesn't works.

So I stopped genymotion emulator. Then I restart ADB (Tools > Android > Unchecked Unable ADB Integration then I've checked again)

Next I've start genymotion emulator again And now the app works on the emulator.

This way worked for me in a very first trial. Thank you. – Jigar May 17 '17 at 05:31 — Jigar, May 17 '17 at 05:31

For Windows,

Close Android Studio and any of your Emulators you are using,

then goto->TaskManager and Kill the process(adb.exe)

After finishing all these First open Android studio followed by emulators.

Sometimes there are conflicts between ADB Genymotion and ADB SDK because both of them use the same port. So I recommend always set up ADB Genymotion to use the ADB SDK, in that way to avoid incompatible issues.

Genymotion-> Settings -> ADB -> Use custom Android SDK tools (here your set up your sdk android location).

I solve this problem at last! I finally found the program name of the pid and I kill it in the task manager.

The way to detect is described in the question:

adb nodaemon server

Output:

cannot bind 'tcp:5037'

2.and then netstat -ano | findstr 5037 to find who takes this port.

Get the pid and find it in the task manager. Please note that the process tab may not show the column of pid, we should include it by setting.

In my case, it is tfadb.exe who takes this port! This is a Chinese Video program client! Try to kill it in task manager.

Now I stop it starting from booting. The problem is solved.

Does the fact that it has "adb" in its name and uses port 5037 mean it's a tool for video on top of the ADB capability of an Android device? Or is it purely coincidence? – Chris Stratton Oct 03 '14 at 16:21
@ChrisStratton , I Think it is just a terrible coincidence! This is an program for windows not for android. – JaskeyLam Oct 03 '14 at 16:25
You may be able to change the port that program uses, or you can change the one ADB uses, either with an environment variable, or in recent versions a command line option: http://stackoverflow.com/questions/3836571/changing-default-port-i-e-5037-on-which-adb-server-runs – Chris Stratton Oct 03 '14 at 16:29

Just goto the task manager on your PC, and kill adb.exe, then back to your android studio. it should initialize and reconnect.

disconnect any usb connected android devices. I was tethering to my laptop via my cellphone for internet connection. I got the adb start server failed error with loopback error "port is only used for one socket connection".

I disconnected my cellphone usb connection from my laptop and now android studio recognizes my genymotion emulator and another android device I have connected via usb in the deployment target box.

Check the firewall of the system. May be the "allow app to communicate through windows firewall" may have blocked android studio.

I have tried all of the solutions proposed above, but no one of them solve my problem. I had some hour of hadaches trying to solve this problem on my laptop (Ubuntu 20.04). This is how I came to solve it finally.

The problem was that the adb default port 5037 was already taken by another, so the solution became simple :

kill the process running on that port (5037) then launch the adb manually
launch the adb on another port :

user~$ adb start-server -P xxxx

Where xxxx represent another port

There may be a problem with Windows 11. to solve that issue follow the steps

Go to the android studio app Right-click the app Go to Properties Go to compatibility Check the Run this program in compatibility mode Select windows version 10 or 8 or 7 Then apply and ok

After these changes start the Android Studio App, This is works for me.
