I thought it would be nice to customized my app theme so I chose all the colors and added them in the colors.xml file. Then I referenced them in Android Studio theme editor. I believe this was not a good thing to do as I can't undo it. When I try to build my app I get these errors:
Error:(7, 21) No resource found that matches the given name: attr 'textColorPrimary'.
Error:(8, 21) No resource found that matches the given name: attr 'windowBackground'.
Go to you project location in File Explorer and make sure to delete the
build folder from your app's module.
Then, go back to your project and find the
values.xml, remove those lines now and rebuild it. When you click on the error and edit it, you're probably editing the build generated file
