Xamarin Forms Cannot Archive APK

Question

I was using the target framework (Android 9) until I used a nuget package that required minimum target framework of Android 10, when I changed the target framework I was not able to archive the apk anymore. I get the following error:

Answer 1

It sounds like you haven't updated to AndroidX completely. Please make sure all the dependencies are updated and all support libraries are replaced with AndroidX. There is a complete guide on how to approach the AndroidX migration, it's not just a simple switch in VS:

ps: even if you cannot copy the error message, it makes sense to spend some time and rewrite it in the text so other people can benefit from this post, otherwise it won't be searchable.

Answer 2

Ok thanks to @ToolmakerSteve I fixed it by changing the archive directory by going to: tools >> options >> xamarin >> android settings then changes Archive location
