Prepare for Google Play code optimization requirements

Starting in February 2027, Google Play requires at least 25% coverage for each of code optimization, shrinking, and obfuscation. This applies to apps with more than 10 MB of DEX code and games with more than 50 MB. See the Google Play requirements and original announcement.

On .NET 11, enable R8 for Release builds in your .csproj file:

<PropertyGroup Condition=" '$(Configuration)' == 'Release' ">
  <AndroidLinkTool>r8</AndroidLinkTool>
</PropertyGroup>

When R8 is enabled, .NET 11 defaults AndroidR8ObfuscationMode to private-members. You don't need to set this property unless your project overrides it. This differs from .NET 10, where the default is disabled.

These settings apply to Java bytecode (DEX), not managed .NET assemblies. Test your Release build, then check the optimization, shrinking, and obfuscation percentages in Google Play Console's App bundle explorer to confirm that your uploaded bundle meets all three thresholds.
