.NET 10 app built with AndroidEnableAssemblyCompression=false crashes at launch: cannot locate symbol "compressed_assembly_count" #13247
.NET SDK 10.0.402, Microsoft.Android.Sdk 36.1.69 and 36.1.118
Description
A Release build with AndroidEnableAssemblyCompression=false doesn't start: libmonodroid.so references compressed_assembly_count, which isn't there when compression is off. It happens on both Mono and CoreCLR (UseMonoRuntime=false). The same app on .NET 11 RC2 runs fine.
Install the signed APK and launch it (API 36 x64 emulator)
Did you find any workaround?
Only leaving compression on.
