There is currebtly a bug in Butler where single file uploads end up zipping the uploaded files.
As a result, you get a zipped archive containing the APK file instead of the APK file on itch projects.
I would like to request an archive detection feature and unpacking before install.
Or manual setting of installed state for a product.
Example project (caution - nsfw): https://thearcadean.itch.io/corrupted-kingdoms
Thanks for telling about the Butler bug. Unpacking archives was a low-priority to-do item for a while, this makes it higher priority.
Sorry, it took me far too long to get around to this, and now I actually can't find any Android games packaged as ZIPs. The project you linked to seems to have been updated. I will keep this feature request open until I find a test case for it.
Nevermind, found a test subject. Paid game but I have it thanks to the Ukraine bundle: https://nerdmonkeys.itch.io/detective-case-and-clown-bot-in-murder-in-the-hotel-lisbon
