I want to download all the repositories that are necessary to work with android studio offline. What the official documentation says does not work at all well, since, at least once you need internet, and each time you add a new library too. I already have the google maven, but I see that not all packages are there. Although we are in 2020, the availability of the internet where I live is not very good, and it is expensive. What do I need to download to really work offline? Is there a way to download the jcenter? Cheers
