You need to add a reference to Mono.Android.Export.Dll when you use ExportAttribute or ExportFieldAttribute

Question

My code works fine, but when I added fragments with a new namespace to the project, I began getting the error

You need to add a reference to Mono.Android.Export.Dll when you use ExportAttribute or ExportFieldAttribute

I've searched online and found several mentions of unlinking assemblies, but I've also read that this will cause additional errors.

Does anyone know how to solve this bug?

Answer 1

I found the answer. Right click references and search Export. Just add the Mono.Android.Export to your project.

Answer 2

I added reference like @Jeremy Said, it's working

Answer 3

If you're using JetBrains Rider, you can solve the issue by adding the Mono.Android.Export reference to your Android .csproj file:

<!-- ExampleApp.Android.csproj -->
<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    ...
    <ItemGroup>
        <Reference Include="Mono.Android" />
        <Reference Include="Mono.Android.Export" />
    </ItemGroup>
    ...
</Project>

Answer 4

You don't need download dll from the web if you cant find it in the reference manager

just do following steps:

1. Set the target framework to Android 4.4 kit kat
2. Add reference mono.android.expert.dll
3. set targetFramework as last good target framework

Clean solution and rebuild

I hope it helps you.
