created issue #1

Jun 16, 2020 09:13AM

The doc about how to load and display paged data with Paging 3.0 clearly explains how to show progress and error views but it doesn't cover how to handle the case of an empty result. Also the samples seem to not support that case.

I'm new to the Paging library and I find it non trivial to determine what is the right LoadingState to listen to. I assume it's the refresh state, but even there it's not clear how to determine whether the result is empty or not.

Maybe this suggestion should go to a separate issue but I think it would be nice to reuse the same LoadStateAdapter approach as that would allow to build nice reusable loading-empty-error page components.

Expand native target support for annotation and collection libraries

- Enable watchos and tvos download in importMaven
- Add support for watchos and tvos targets in AndroidXMultiplatformExtension
- Enable watchos and tvos in :annotation:annotation
- Enable linuxArm64, watchos, and tvos in :collection:collection

This work is required as we work towards setting up native stubs for
compose projects.
