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:

1. I type:

    adb nodaemon server

   Output:

    cannot bind 'tcp:5037'

2. Then netstat -ano | findstr 5037 netstat -ano | findstr 5037

   I did find a pid of 7416 who listen in 127.0.0.1:5037

3. I use taskkill /pid 7416 -f to kill it.

4. I type netstat -ano | findstr 5037 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?

Answer 1

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.

Answer 2

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).

Answer 3

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.

Answer 4

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:

1. adb nodaemon server

Output:

cannot bind 'tcp:5037'

2.and then netstat -ano | findstr 5037 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.

I solved by End task "adb.exe" background process from task manager. and Start adb thats it :)

Answer 9

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.

Answer 14

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:

1. kill the process running on that port (5037) then launch the adb manually

2. launch the adb on another port:

   user~$ adb start-server -P xxxx

   Where xxxx represent another port
