It would be great if D8 could use the latest Java 8 backporting APIs from desugar:

Because of

issue 37042460

there is now also a fix for ConcurrentHashMap for pre-23 API levels added in

Please, just STAR THE ISSUE and DON'T COMMENT +1. Every comment results in an email.

I really wish the issue tracker would just auto-delete "+1" comments without sending out notifications.

jo...@gmail.com <jo...@gmail.com> #13Apr 29, 2019 08:59PM

+100

Dear jo..., others,

Google also decides issue priority by how many people starred a particular issue.
Everyone who starred an issue did so, because they were insterested in updates *from Google* on said issue.
Everyone who starred an issue gets an email about every comment on said issue. That, among others, includes unrelated comments and "plus ones" from undisciplined or, in your case, straight up malicious people.

I don't want to get your spam. I think I'll unstar this. I don't think I care about this issue anymore. Was that your goal? To move the star counter down and drive this issue into oblivion because everybody gets sick and tired of your behavior?

You ought to go home and rethink your life. Be a good neighbor on the Internet. Spread the message.

Thank you.

P.S. Don't reply to this message and upset 500+ PEOPLE again, like I just did.

Any update on this? this is really blocking us from using some of the java8 APIs (e.g. java.time). Though Bazel supports desugaring, its uses dx not D8.

gi...@gmail.com <gi...@gmail.com> #22Oct 6, 2019 11:37AM

Until this is solved, you can use the Android RetroFix gradle plugin (

https://github.com/SgtSilvio/android-retrofix) to automatically backport most Java 8 APIs (java.util.function.*, Optional, CompletableFuture, java.util.stream.*) to Android APIs < 24

an...@gmail.com <an...@gmail.com> #23Oct 6, 2019 10:00PM

Nice, thank you for letting us know about RetroFix tool, does it back port java.time? The project page API list does not contain java.time in it.

h4...@gmail.com <h4...@gmail.com> #24Oct 6, 2019 10:33PM

Then, obviously, it doesn't…

gi...@gmail.com <gi...@gmail.com> #25Oct 7, 2019 10:32PM

I added backporting of java.time to the RetroFix plugin with version 0.3.0.

You may want to take a look at

https://github.com/JakeWharton/ThreeTenABP if you haven't already.

gu...@gmail.com <gu...@gmail.com> #27Oct 12, 2019 02:05PM

fyi: The latest version of ProGuard 6.2.0 has support to backport java.time and the stream API to the streamsupport and ThreeTenABP libraries accordingly.
