At the moment, we’re not targeting plain Java for cert4android, but it would be a good idea if other people are actually using it, too. For which projects are you using it? We are using it for Nextcloud Notes ( https://github.com/stefan-niedermann/nextcloud-notes/ ) and I plan to integrate it in another Nextcloud-related app. Until then, does CustomCertManager.Companion.resetCertificates(Context) work? Yes, that works! Thanks, that’s sufficient for now. But it would be nice, if you could keep in mind that also (plain) Java projects may use cert4android. Thanks!

Great! I think that you can switch back to your old notation using 26.+ (if you really want), since you’ve added the new Google maven repository. However, you have the same “problem” with the build tools. And for both cases, Android Studio should notify you in case of updates. Unfortunately, there was no notification for the new maven repository.
