ddms: 'adb.exe,start-server' failed — run

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

   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 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

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 2

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

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 6

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.
