Type androidx.lifecycle.ClassesInfoCache$CallbackInfo is defined multiple times

MushKPN commented 1 year ago

Android application type

Android for .NET (net6.0-android, etc.)

Affected platform version

VS2022 MAUI .Net 7

Description

Visual Studio 2022 Enterprise 17.6.4 - Xamarin.Android SDK 13.2.0.6 (d17-5/a200af1)

My project targets net7.0-android. When trying to compile my new MAUI project, I've got the following issue : Type androidx.lifecycle.ClassesInfoCache$CallbackInfo is defined multiple times

Here is my .csproj package configuration :

<ItemGroup>
  <PackageReference Include="CommunityToolkit.Maui" />
  <PackageReference Include="CommunityToolkit.Maui.Core" />
  <PackageReference Include="CommunityToolkit.Maui.Markup" />
  <PackageReference Include="GoogleApi" />
  <PackageReference Include="Microsoft.Extensions.Logging.Debug" />
  <PackageReference Include="Telerik.UI.for.Maui" />

  <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" />
  <PackageReference Include="Xamarin.AndroidX.Annotation" />
  <PackageReference Include="Xamarin.AndroidX.Lifecycle.Common" />
</ItemGroup>

On my solution, I'm also using central package management, here is my Directory.Packages.props

I'm pretty much new to MAUI development, so please let me know if there's something more I can add in order to help investigating this issue

Steps to Reproduce

Add a new MAUI application project (limited to Android .Net 7) Try adding packages with Directory.Packages.props Try compiling

Did you find any workaround?

Also, my MAUI project (NDC.Mobile) references another .NET 7 library project (NDC.Utils) which has the following .csproj :

<TargetFrameworks>net7.0-android</TargetFrameworks>
<TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.17763.0</TargetFrameworks>

@MushKPN

Thanks for the feedback. Please try updating to the latest packages AndroidX and GPS-FB-MLKit

moljac commented 1 year ago

Please add those 2 dependencies:

        <PackageReference Include="Xamarin.AndroidX.Activity" Version="1.7.2" />
        <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.7.2" />

And please report if this works.

MushKPN commented 1 year ago

Thank you for your reply, can you elaborate a bit more on which package I should install/update ? (as there are many Xamarin.AndroidX. packages)

MushKPN commented 1 year ago

Please add those 2 dependencies:

      <PackageReference Include="Xamarin.AndroidX.Activity" Version="1.7.2" />
      <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.7.2" />

And please report if this works.

Alos, when trying to add the specific version on these two packages, my compilation breaks with error NU1008 (Projects that use central package version management should not define the version on the PackageReference items but on the PackageVersion items: PackageId.) Adding Condition="'$(UseMaui)' != 'true'" in Directory.Packages.props for these two doesn't seem to help :(

MushKPN commented 1 year ago

In order to pinpoint the culprit, I disabled central package management for my MAUI project.

Here is my csproj configuration :

    <ItemGroup>
        <PackageReference Include="CommunityToolkit.Maui" Version="5.2.0" />
        <PackageReference Include="CommunityToolkit.Maui.Core" Version="5.2.0" />
        <PackageReference Include="CommunityToolkit.Maui.Markup" Version="3.2.0" />
        <PackageReference Include="GoogleApi" Version="5.0.3" />
        <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="7.0.0" />
        <PackageReference Include="Telerik.UI.for.Maui" Version="5.2.0" />
        <PackageReference Include="Xamarin.AndroidX.Activity" Version="1.7.2" />
        <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.7.2" />
        <PackageReference Include="Xamarin.AndroidX.Annotation" Version="1.6.0.3" />
        <PackageReference Include="Xamarin.AndroidX.Lifecycle.Common" Version="2.6.1.2" />
    </ItemGroup>

I'm getting the following (slightly different from before) :

Those look good

        <PackageReference Include="Xamarin.AndroidX.Activity" Version="1.7.2" />
        <PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.7.2" />
        <PackageReference Include="Xamarin.AndroidX.Annotation" Version="1.6.0.3" />
        <PackageReference Include="Xamarin.AndroidX.Lifecycle.Common" Version="2.6.1.2" />

Also, my MAUI project (NDC.Mobile) references another .NET 7 library project (NDC.Utils) which has the following .csproj :

<TargetFrameworks>net7.0-android</TargetFrameworks>
  <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net7.0-windows10.0.17763.0</TargetFrameworks>
   <OutputType>Library</OutputType>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
  <LangVersion>Latest</LangVersion>
  <Nullable>disable</Nullable>

And no package reference related in any way to Android

After removing this reference, my issue has gone away. It seems impossible to use reference a .Net 7 library project inside a MAUI project

MushKPN commented 1 year ago

I finally figured it out : my NDC.Utils project I was referencing was incorrectly configured.

Here is the simplification I found :

<PropertyGroup>
    <TargetFrameworks>net7.0</TargetFrameworks>
    <OutputType>Library</OutputType>
    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <LangVersion>Latest</LangVersion>
    <Nullable>disable</Nullable>
  </PropertyGroup>

Adding a target to net7.0-android was apparently adding duplicated references, hence my problem.

Thank you for your time.
