What happens to Adobe Air applications when Flash becomes unsupported in 2021?

Question

I understand browser-based Flash apps will become unusable at the end of the year when browsers drop support: https://blog.adobe.com/en/publish/2017/07/25/adobe-flash-update.html#gs.jasqm6

Extended support for Flash applications, including a new Flash runtime, is available through a license with Harman: https://services.harman.com/partners/adobe

My question: what happens to existing Air applications with a Flash dependency in 2021? Will they continue to technically function technically, but run unsupported?

More specifically, would it be technically feasible to port a browser-based Flex 4 application to run as a standalone desktop Air app?

Answer 1

As Adobe announced in their blog post at the end of May 2019, HARMAN have taken on the platform support and feature development of the AIR software.

HARMAN intends to continue supporting AIR on the existing platforms - Android, iOS, Windows, and macOS - and working with the existing IDEs, in order to make the transition from Adobe's versions of the SDK to HARMAN's version as seamless as possible. AIR will now be provided on a commercial basis, with a free version available for certain eligible individuals/companies, and then with a subscription to use the tools provided by the AIR SDK.
