I am a devoted “Computer guy”. Started in 1980 or so. I have been self studying ANDROID development for almost 6 years now and still fell like I know nothing. It changes soo fast and there is soo much to know. My goal is to finish the Kotlin and Android Development featuring Jetpack book then try to take and pass the GOOGLE certification test. I have MANY books on ANDROID programming and many of them leave you hanging with examples that don’t work any more because the development environment has changed and they never updated their code. As I begin my path in this book I find myself in the same position on page 8. The app won’t build because it can’t find ‘kotlin-version’ for object. So here I am looking for a way to make this work. Disappointed again but still trying.
