Gary D. Gregory commented on COMPRESS-611:
------------------------------------------
Hi [~dreamingincode]
Thank you for your detailed explanation.
I do not see us breaking binary compatibility on purpose to support Android
5.0. Maintaining binary compatibility is extremely important to avoid jar hell
and breaking applications.
Your best and simplest path is to use version 1.20.

> Key: COMPRESS-611
> URL: https://issues.apache.org/jira/browse/COMPRESS-611
> Project: Commons Compress
> Issue Type: Bug
> Affects Versions: 1.21
> Reporter: Hai Zhang
> Priority: Major
>
> The change
> https://github.com/apache/commons-compress/commit/06e05dab3bcb9044cc599f0ff18be78c54a8fbae
> added a static LinkOption[] field into IOUtils, and also made use of
> LinkOption in tar code.
> However, LinkOption is a Java 8 class that's only available on Adnroid 8.0
> and beyond (added in API 26 according to
> https://developer.android.com/reference/java/nio/file/LinkOption ). And with
> the static field in IOUtils, which will result in loading the LinkOption
> class during IOUtils class initialization, this suddenly made all classes
> referencing IOUtils require Android 8.0.
> In comparision, most of the functionalities in commons-compress 1.20 was
> working fine on Android 5.0+.
> I discovered this because a real user wrote to me about this issue, and
> generally speaking a lot of users in developing countries may still be using
> older devices, so it seems to me supporting Android 5.0+ may still be a good
> thing. Meanwhile according to
> https://www.androidpolice.com/googles-latest-android-version-distribution-numbers-show-11-in-dead-heat-with-10/
> , raising supported Android platform version from 5.0 to 8.0 will result in
> the percentage of supported device to drop from 98% to 82.7%, a >10% decrease.
> So could you kindly consider supporting Android 5.0 again by making the usage
> of Java 8 NIO file APIs optional?
