Transparent navigation bar causes UI issues on pre-Q devices about edge-to-edge HOT 6 CLOSED

Fair enough. I've just pushed update to navigation bar color for v23 and new v29 colors.xml

from edge-to-edge.

Thanks for reporting this. Transparent navigation bar can cause contrast issues on some [v23..29) device indeed. Unfortunately this issue is device specific and can only be fixed for all devices by applying opaque black color instead of transparent one, which is not always wanted.

I added the Navigation-Bar-Transparency wiki page explaining the issue and showing how to solve it. Main readme page was updated as well. No changes to the library or demo app are actually needed IMHO, because the library doesn't control the color of the navigation bar. It's a responsibility of developers using the library.

Hope it helps.

Thanks. I am quite late with the changes I wanted to add into README.
Yes, I understand that this is device specific. Just wanted to give a heads up, since previously there were no mentions of such possible issues, so it could confuse some devs.

As to updates to sample app - I would change theme to have this color setting for the navigation bar to values-v29, since some devs might just look at you sample as reference for their code base.
So just a minor addition to play safe even for those, who don't read manual carefully 🙃
