Are you compiling in Release mode? The trimmer doesn't run in Debug mode.

You also might want to try .NET 9. I'm not sure that MAUI was fully trimmer enabled in .NET 8.

@jpobst I updated my VS 2022 to .NET 9 latest version, I created a project again and compiled it in Release mode, but I still have the same problem.

@RobersonGazolli have you disabled the use of r8 by any chance? Its usually r8 which is responsible for removing unused java types from the java side of the app.
