I've also used Appium doctor to troublkeshoot the set up issues and this is what it said:

info AppiumDoctor Bye! Run appium-doctor again when all manual fixes have been applied!

I don't know why is says that I haven't set the env variables when I have already done this in Windows.

Solution

  • For some reason after a few server restarts and command prompt close and re-opens I ran the Appium doctor and it said that it could find ANDROID_HOME

    I did add C:\Users\slai6\AppData\Local\Android\Sdk\tools to my Path though.

    Honestly, I am not sure what fixed it but it is working now !
