Using ionic + Cordova in visual studio i keep getting "No installed build tools found. Install the Android build tools version 19.1.0 or higher."

Question

I have seen a lot of posts about this, but none of the solutions in those posts solve my problem. I have installed the android sdk according to how it should be installed and added the ANDROID_SDK_ROOT system variable.

Here's my folder structure: folder structure

And here's my system variables System Variables

If go to powershell and type sdkmanager --list --verbose it will list all of my installed packages and it includes all of the build tools. yet when i run ionic cordova run android --verbose --no-native-run in visual studio i get the following error:

I couldn't get it to work wit the standalone android sdk. I had to uninstall it and install android studio.
