Xamarin Android appears to miss some R.attr values within a .aar when creating the .apk #5937

Closed alexanderdibenedetto closed 6 months ago

alexanderdibenedetto commented 3 years ago

I'm struggling with a binding for Xamarin.Android. The binding generates perfectly fine, but some R.attr values appear to be missed in the final APK. I've got every other aspect of this library working as expected. When running their APK as built in Android Studio, I don't encounter any issues. Everything builds and loads correctly but for some reason it crashes when their Netverify MRZ library references an R.attr value from the Netverify library when running the APK built by Xamarin. I have the Netverify library referenced in the binding for the Netverify MRZ library.

I'm not even using the bindings within the Netverify MRZ library - just using the Netverify library's bindings. The MRZ library is just required for the type of scanning I'm doing (passports).

@jonathanpeppers @dellis1972 I suspect this is some sort of packaging issue, so I'm gonna let you guys take first stab at it.

With support for Classic Xamarin.Android ended May 1st, 2024, this issue is likely no longer relevant.

If this still persists in .NET 8+, please open a new issue with updated information based on net8.0-android or greater. Please include a link to this issue for context.
