Xamarin.Android error/warning XA4301
Issue
This message indicates a problem adding an Android native library (*.so file) to your Xamarin.Android project's APK file during the build.
Situations include:
- Xamarin.Android is unable to determine the Android ABI for the library.
- If coming from an assembly reference, Xamarin.Android will skip this file and emit a warning mentioning the file.
- If coming from within the Xamarin.Android project, Xamarin.Android will give an error mentioning the file.
- Duplicate instances of native libraries were found.
- Xamarin.Android will include the first entry in the APK and emit a warning indicating the duplicate file.
See the Android documentation to learn about Android ABIs.
Common causes:
- The Xamarin.Android project contains either an
@(EmbeddedNativeLibrary)
or@(AndroidNativeLibrary)
build action in a directory that is not named a valid Android ABI. - The Xamarin.Android project is referencing two Android library projects
that contain the same native library via an
@(EmbeddedNativeLibrary)
or@(AndroidNativeLibrary)
build item.
Solution
- Place any Android native libraries within a directory in your Xamarin.Android project named with the appropriate ABI, such as arm64-v8a, armeabi-v7a, x86, or x86_64.
- Remove any duplicate instances of the native library.
