This change affects only APK distributions. In App Bundle distribution format which is used by Google Play Store native libraries are not compressed already.

Whether to use the legacy convention of compressing all .so files in the APK. If null, .so files will be uncompressed and page-aligned when minSdk >= 23.

What happens for minSdk 21?
What are the pros and cons? Will apk size increase significantly?

On minSdk 21 .so files will continue to be extracted from the APK, so they will exist in 2 copies on the device instead of one and one compressed. Android 5 users are victims of this change but how many of them are there? Many apps in Play Store have minSdk 23 these days.
Raw APK size increase increased significantly. webDebug APK with all ABIs is about two times larger (83Mb vs 154Mb). But:
a) gzipped size of the APK slightly decreases(66Mb vs 60Mb), because compression works better if applied at the end. So less data is consumed if HTTP gzip is enabled.
b) storage occupied by the app decreases because it no longer necessary to extract .so files. So only one copy of each library is on the disk, instead one and a half.

So it could negatively affect distribution channels which do not support HTTP gzip and use single APK for all ABIs. And it looks like F-Droid is one of them which is sad.

And also all our apks distributed via Github directly or via Obtainium? And likely the ones distributed via Accrescent.
What about Huawei store?

Is it possible to apply this change to Google build flavor only?

This change doesn't affect Google Play, it uses different packaging mechanism – app bundles, in which compression is already disabled.

Huawei Store also supports App bundles, but I don't know how Organic Maps are uploaded there.

So what current OM distribution channels that would benefit from this change for sure? (i.e. have single apks and http gzip enabled)

SDK < 23 isn't a big deal, but we'll likely need to drop support for it sooner or later.

a) gzipped size of the APK slightly decreases(66Mb vs 60Mb), because compression works better if applied at the end. So less data is consumed if HTTP gzip is enabled.

This is huge!

This change doesn't affect Google Play, it uses different packaging mechanism – app bundles, in which compression is already disabled.
Huawei Store also supports App bundles, but I don't know how Organic Maps are uploaded there.

Both Google Play and Huawei AppGallery are distributed via AAB bundles.

So it could negatively affect distribution channels which do not support HTTP gzip and use single APK for all ABIs.

The F-Droid team initially requested that we reduce the APK size to 50MB (without the World.mwm file).
