为.NET MAUI创建Amazon Device Messaging绑定库启动报错求助

我基于amazon-device-messaging-1.2.0.jar制作.NET MAUI的Android绑定库，项目构建完成后绑定功能看似正常，编译和运行环节均无问题，但应用实际启动时会抛出错误：

'Stub! You are bundling a stubbed jar in the apk! Please move it to the classpath instead.'

我的Android绑定库.csproj文件内容： #

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net8.0-android</TargetFramework>
    <SupportedOSPlatformVersion>21</SupportedOSPlatformVersion>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <InputJar Include="amazon-device-messaging-1.2.0.jar" />
  </ItemGroup>
</Project>

Metadata.xml文件内容： #

<metadata>
    <!-- Package Name -->
    <attr path="/api/package[@name='com.amazon.device.messaging']" name="managedName">Amazon.Device.Messaging</attr>

    <!-- ADM -->
    <attr path="/api/package[@name='com.amazon.device.messaging']/class[@name='ADM']" name="visibility">public</attr>

    <!-- ADMMessageHandlerBase -->
    <attr path="/api/package[@name='com.amazon.device.messaging']/class[@name='ADMMessageHandlerBase']" name="extends">mono.android.app.IntentService</attr>
    <attr path="/api/package[@name='com.amazon.device.messaging']/class[@name='ADMMessageHandlerBase']" name="visibility">public</attr>

    <!-- ADMMessageHandlerJobBase -->
    <!-- ADMMessageReceiver -->
</metadata>

MAUI项目中引用生成DLL的方式： #

<ItemGroup>
  <Reference Include="AmazonDeviceMessaging">
    <HintPath>..\..\AmazonDeviceMessaging\AmazonDeviceMessaging\bin\Release\net8.0-android\AmazonDeviceMessaging.dll</HintPath>
  </Reference>
</ItemGroup>

我还尝试过使用AndroidLibrary（Bind和Pack的所有选项）、EmbeddedJar、InputJar、LibraryProjectZip以及ReferenceJar来构建绑定库，但问题仍未解决。请问如何让我的MAUI项目不再抛出这个错误？
