Slackbuilds has a package for Android Studio (for slackware 15.0) but that is the version 3.5 from August 2019. Anyone know how to get a more recent slackware package?

Is this the same thing from Jet Brains?

I downloaded 2021.1.1.23 changed the Slackbuild version number. It went fine. Also if you have the Jet Brains toolbox you can install it from there too.

SlackBuild scripts created so they can be used with different versions as much as possible. For example:
Of course, there are numbered scripts in the repo which can't use this.

I was able to download the latest Android studio file (android-studio-2021.1.1.23-linux.tar.gz), change its file name to the one on Slackbuilds (android-studio-ide-191.5791312-linux.tar.gz), and then ran the Slacbuilds script. As far as I could tell, it worked, at least I am able to open the software and do basic things. However, the AVD feature does not seem to be working. It just quits with "unable to start AVD". I am not sure if that has something to do with the fact that I artifically change the version number, or if it is due to something else.

Hello asarangan,

For avd proglem, you better close this thread and open a new one for it. I think more people would see it and help.

I managed to make it work here (Slackware 15.0).
The only issue/problem I had was permissions on /dev/kvm
but once sorted, it runs fine

Make sure you have no error message related to /dev/kvm upon adding a device (virtual in my case)
