Xamarin.Android warning XA4305

Issue

The CreateMultiDexMainDexClassList, CompileToDalvik or R8 MSBuild task encountered a multidex.keep file that was not found on disk. You can customize multidex settings for your Xamarin.Android application by adding files with the MultiDexMainDexList build item, which are combined into a final multidex.keep file.

To learn more about multidex and how it relates to Android development, see the Android documentation.

Solution

Verify you are not declaring a MultiDexMainDexList build item that does not exist.

Consider submitting a bug if you are getting this warning under normal circumstances.
