I am stuck a whole afternoon trying to run again my small Android/Kotlin application in Android Studio. The message pasted on this question topic suddenly nocked me down.

I have done these tentatives:

1 - cold boot (On Virtual Devices screen > Actions > Cold Boot Now)

2 - I deleted my previous Virtual Device and I downloaded a new one (Nexus One)

3 - I followed all steps from other stackoverflow answer

3.1

cd C:\Users\Jimis\AppData\Local\Android\Sdk\platform-tool

adb kill-server
adb.exe start-server
adb devices -l

3.2

deleted plataform-tool and redownlowaded it from SDK Plataform

3.3

restart computer

I am completely stuck.

Something called my attention: why so many PIDs to port 5037. See bellow that initially when I started Androdi Studio I had only 3 and after I tried debug my application I got a lot more.

in case it is relevant I just aupdated to Android Studio 4.0 and same issue.

Reading a lot on stackoverflow I reached this other issue

I tried added advancedFeatures.ini in my C:\Users....android with 

Vulkan = off
GLDirectMem = on

I don't know exactly what I did but I tried it anyway and I am still getting same issue. In this same stackoverflow discussion I noted someone talking about hyper-V.

In case it is relevant, I have turned off Hyper-V some time ago in my Windows 10 because I had to use VirtualBox for other reasons (OpenShift/minishift). I don't think it has relathionship with my issue because until 2 days ago I had not such problem with port 5037. BTW, I am curious: does Androids Emulators depend on HyperV somehow?

1) Before I started Android Studio I had no connection to 5037 as expected

C:\Users>netstat -ano | findstr "5037"

2) Then I started Android Studio and I see at least three connections to port 5037. 

C:\Users\Cast>netstat -ano | findstr "5037"
  TCP    127.0.0.1:5037         0.0.0.0:0              LISTENING       11880

  TCP    127.0.0.1:54602        127.0.0.1:5037         ESTABLISHED     348

3) And when I click on Debug app (shift + F9) I get two messages errors on left bottom side of Android Studio 

Emulator: emulator: ERROR: AdbHostServer.cpp:102: Unable to connect to adb daemon on port: 5037

Emulator: socketTcpLoopbackClientFor: error: fd 56668 above FD_SETSIZE (32768)

and a lot of connections with numerous TIME WAIT. It seems so weird to me.

How do you fix Cannot reach adb server attempting to reconnect?

Check if there's an "adb.exe" file in your "Android/Sdk/platform-tools" folder. If yes, then its your antivirus causing the issue. It worked well when I disabled it. If not this, you might wanna try enabling "Virtual Machine Platform" on your "Windows Features" and make sure "Windows Hypervisor Platform" is disabled.

What is adb connection error?

i got this problem that is annoying me after updating to 1.3 , i fired up Android Studio and got a message saying : ***Unable to establish a connection to adb This usually happens if you have an incompatible version of adb running already. Try reopening Android Studio after killing any existing adb daemons.

1 Answers

This is likely caused by insufficient permissions. Run Android Studio or your command prompt (whichever you prefer) as an administrator and that should solve your problem.
