Example messages

warning XA4231: The Android class parser value 'jar2xml' is deprecated and will be removed in a future version of .NET for Android. Update the project properties to use 'class-parse'.

Issue

The Android class parser jar2xml has been deprecated.

Solution

To resolve this warning, update the Android Class Parser setting in the Visual Studio project property pages or the .jar file parser setting in Visual Studio for Mac to class-parse. This corresponds to the class-parse value for the AndroidClassParser MSBuild property in the .csproj file:

<PropertyGroup>
  <AndroidClassParser>class-parse</AndroidClassParser>
</PropertyGroup>
