Acabo de crear un apk firmado, después de lo cual agregué dos archivos a mi proyecto: my_web_activity.xml y MyWebActivity.kt. Después de compilar el código, recibí el error: "Nombre de entrada 'res/color/material_on_surface_disabled.xml' chocó" No se especificó nada más.

mi_actividad_web.xml

So I don't know which solution works. Cheers!
