I understand that Wine 3.16 doesn't run on android 8.1 (Just tested on my OnePlus 6).
While I don't think I'd be of help fixing the issues, I wonder the following:

1.) What is the big difference between android oreo and it's predecessors that makes Wine 3.x working on the one but not the other?

2.) Is a similar problem to be expected for later android versions once wine is working for android 8.1?

Thanks in advance and for all your efforts in general!

Been months since this bug was known which is acknowledged, but no fix yet. Dont think he/she/they even care about it anymore

Let's be a bit more optimistic, okay? We don't know what the issue exactly is. At least I don't.

Has anybody checked release 3.19 on android 8.1 / 9.0 yet?
(Not that I'd have my hopes up, I'd believe a fix like that would be in the description of the download file)
