Brief

I am new to Flutter. I installed Android Studio and Flutter source code as mentioned in Flutter's Installation guide for windows. I had a problem with the lack of storage space on C:Drive as mentioned in my previous question, so I installed Android Studio entirely on my E:Drive using Jet Brains ToolBox instead of breaking my head with symbolic links for everything, following the answer of the previous question, but I ran into another problem after having everything on my E:Drive, whenever I try to run an Android Virtual Device or run flutter doctor -v , I get the following error:

Error Message

Connected device (the doctor check crashed)
    X Due to an error, the doctor check did not complete. If the error message below is not helpful, please let us know about this issue at https://github.com/flutter/flutter/issues.

I also tried to use VS Code with the flutter-dart extension but I keep getting the message Flutter daemon has terminated.

When I tried to run the adb server manually, I keep getting the following error

* daemon not running; starting now at tcp:5037
could not read ok from ADB Server
* failed to start daemon
error: cannot connect to daemon

So I even tried to kill the server and got the following error

cannot connect to daemon at tcp:5037: cannot connect to 127.0.0.1:5037: No connection could be made because the target machine actively refused it. (10061)

Little More Info

I have the following folders at these locations:

Folder Location
Android Studio E:\Users{user}\AppData\Local\JetBrains\Toolbox\apps\AndroidStudio
Flutter D:{user}\Documents_HDD\Programming\Flutter\flutter
Android Sdk E:\Android\Sdk
.android E:\Android.android

Also the .android folder was stored in AppData\Local but I observed that flutter tried to create another .android folder inside the Sdk folder and that caused an error stating avd path is broken, so I moved the .android folder into Sdk folder.

I have been facing this issue for a few months now. I have searched the net for some solutions but none of them has worked. I tried the following

  • Adding the environment variables ANDROID_SDK_ROOT, ANDROID_AVD_HOME, ANDROID_PREFS_ROOT and path variables to platform-tools and tools folders present in the Sdk folder
  • Allowing adb.exe through the firewall and antivirus program.
  • I even checked if there is any other program running at tcp:5037 port but there was no program using that port.

None of these solutions worked. Can someone please help me with this problem? I want adb to work properly for flutter development.

If any further information is required, please let me know in a comment rather than an answer.
