Ionic Failed to find android_sdk_root, cannot build app on phone-CodePudding

When I prompt ionic cordova build android in vscode terminal, after a while it gives me:

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=undefined (DEPRECATED)
Failed to find 'ANDROID_SDK_ROOT' environment variable. Try setting it manually.
Failed to find 'android' command in your 'PATH'. Try update your 'PATH' to include path to valid SDK directory.
[ERROR] An error occurred while running subprocess cordova.

        cordova.cmd build android exited with exit code 1.

        Re-running this command with the --verbose flag may provide more
        information.

I checked my paths and I think it's okay?

Can I get some help please?

I want to test my app on my phone. I already had my phone running on Xamarin.

EDIT(Adding verbose):

I have Android Studio installed on this computer but never executed it on this user. Should I open it? [1]: https://i.stack.imgur.com/BO5wx.png [2]: https://i.stack.imgur.com/qQ4VE.png
