.NET for Android warning XA4304

Issue

The Proguard MSBuild task encountered a ProGuard configuration file that was not found on disk. These files are generally declared in your .NET for Android project with a build action of ProguardConfiguration. However, .NET for Android also generates ProGuard configuration files internally during the build process.

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

Solution

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

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