New Google requirements in 2018 and 2019
Google recently posted new requirements to Android apps.
Anybody knows? - How security metadata inclusion can affect apps already published on Google Play?
Another question - How future changes will be supported by Qt? Especially requirement to support both 32 and 64 bit architectures in one app.
That’s a question you should bring to the Qt Android mailing list. You’ll find Qt’s Android port developers/maintainers. This forum is more user oriented.
ad 1 (recent API): This is only related if the app should be published in the Play store. Qt supports API level 9 upwards. So it's in the responsibility of the developer to meat this criteria.
ad 2 (64-bit support): this is actually the most interesting but by far no show stopper. Also this doesn't happen before August 2019 . So plenty of time ahead for the Trolls to come up with a solution. Just the necessary build steps need to be added to QtCreator's toolchain to also bundle the 64-bit libraries. Unfortunately this means that Qt Android apps increase even more in size! I am looking forward how this will be addressed.
ad 3 (security metadata): as written this is done by Google and needs no interaction by the developer. So nothing to worry about.
