Failing to load shared library 'git2-a418d9d' on android/arm64v8a

I am running a .NET 8 Maui Application on Android 13 (API Level 33) with architecture arm64v8a

In my app i am utilising the nuget package "LibGit2Sharp 0.30.0" that has a transitive reference to "LibGit2Sharp.NativeBinaries 2.0.322".

Upon calling Repository.Init("path/to/my/repo") my app crashes:

System.TypeInitializationException: The type initializer for 'LibGit2Sharp.Core.NativeMethods' threw an exception.
 ---> System.DllNotFoundException: git2-a418d9d
   at LibGit2Sharp.Core.NativeMethods.InitializeNativeLibrary()
   at LibGit2Sharp.Core.NativeMethods..cctor()
   --- End of inner exception stack trace ---
   at LibGit2Sharp.Core.Proxy.git_repository_init_ext(FilePath workdirPath, FilePath gitdirPath, Boolean isBare)
   at LibGit2Sharp.Repository.Init(String path, Boolean isBare)
   at LibGit2Sharp.Repository.Init(String path)

logcat output when executing the Repository.Init method:

[monodroid-assembly] Shared library 'git2-a418d9d' not loaded, p/invoke 'git_repository_init_ext' may fail
[monodroid-assembly] Shared library 'kernel32' not loaded, p/invoke 'LoadLibrary' may fail

I checked the contents of my *.apk file and could correctly locate libgit2-a418d9d.so under lib/arm64-v8a

also the provided lib in the nuget seems to be of correct format/architecture:

$file libgit2-a418d9d.so

libgit2-a418d9d.so: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, BuildID[sha1]=91bb85cb63fc4326cd958916c059432d51053d31, not stripped

dependencies of the lib:

$ objdump -p libgit2-a418d9d.so

libgit2-a418d9d.so:     file format elf64-little

Am i missing something? How could I get more info about why the shared library 'git2-a418d9d' can not be loaded?

Any help appreciated :-)

从报告的 Repository.Init 调用和 LibGit2Sharp.Core.NativeMethods.InitializeNativeLibrary 开始，然后检查 APK 的 lib/arm64-v8a 条目以及 Android logcat 输出。将原生库声明的依赖项与 Android 的加载器要求进行比较；完成的标准是确定加载失败的原因，并记录一种可复现的解决方案。
