Anonymous2023-10-26T06:19:18.6933333+00:00 What settings of your Trimming granularity(right click your project, choose properties, select Android->Options)? If you set it to Link, please set it to the
CopyUsed, then release your application.Can you share your .csproj file?

2023-10-31T06:42:04.3466667+00:00 Based on your error message, this error is from the Mono Ahead of Time compiler, please right-click your project, choose properties, select Android tab-> find Options->AOT, unselect the release & netx.0-android, rebuild your project and release it.
