You are probably doing a bit simpler stuff, if that basic tutorial suffices you. I should have maybe added that I do Android development with Gradle. There you don't as much start with an empty build file to write the tasks to compile your project, but instead have to navigate a pre-existing large build file and figure how to correctly use the Google and Gradle interfaces to integrate to the Android build tools, such as the dreaded AGP (Android Gradle Plugin). Which by the way is actually mostly undocumnented AFAIK!
