Upgrading Xamarin.AndroidX.Lifecycle packages to version 2.6.1 makes the build fail for duplicated classes

Question

Upgrading Xamarin.AndroidX.Lifecycle packages to version 2.6.1 makes the build fail for duplicated classes

XDarinor opened this issue a year ago · comments

Alessandro Morvillo commented a year ago

Android application type

Classic Xamarin.Android (MonoAndroid12.0, etc.)

Affected platform version

Visual Studio 2022 Enterprise, Windows 11, Xamarin.Android, build tools Android 13

Description

Upgrading packages Xamarin.AndroidX.Lifecycle.Runtime from previous version to 2.6.1 causes a Java error:

Error in G:\NuGET\Packages\xamarin.androidx.lifecycle.common\2.6.1\buildTransitive\monoandroid12.0\..\..\jar\androidx.lifecycle.lifecycle-common.jar:androidx/lifecycle/DispatchQueue.class:
Type androidx.lifecycle.DispatchQueue is defined multiple times: G:\NuGET\Packages\xamarin.androidx.lifecycle.common\2.6.1\buildTransitive\monoandroid12.0\..\..\jar\androidx.lifecycle.lifecycle-common.jar:androidx/lifecycle/DispatchQueue.class, obj\Debug\130\lp\150\jl\classes.jar:androidx/lifecycle/DispatchQueue.class
Compilation failed

This will happen also if the update is triggered by updating another NuGet packaged that have a dependecy on Lifecycle packages, like Xamarin.AndroidX.Fragment

Steps to Reproduce

Open solution NuGet packages, then upgrade Lifecycle related packages.

Did you find any workaround?

Just to not update the NuGet packges makes the solution work again.

It is OK. Thanks

Do you think this is enough? What also is needed?

I hope so. Usually it is versions mismatch of the transitive dependencies.

This is big problem:

Android support libraries are not supported anymore.

Android support libraries are not supported anymore.

Mmm this could be a great issue. I think this package could be needed for the Syncfusion Treeview. I will try tomorrow to remove it and see if everything works out.

Mmm this could be a great issue.

I'm not telling this is the root cause, but Android Support causes issues with modern apps which use AndroidX.

I think this package could be needed for the Syncfusion Treeview.

Could be. Try updating Treeview. Though I think you should not need to add some dependency for Treeview manually.

Or try removing Xamarin.Android.Support.v7.RecyclerView and see what screams with errors.

Great.

Same here. Visual Studio for Mac 17.5.3 (build 15), MAUI net7.0 app.

/Users/vromanychev/Projects/PushwooshSDK.DotNet/Sample: Error JAVA0000: Error in /Users/vromanychev/.nuget/packages/xamarin.androidx.lifecycle.common/2.6.1/buildTransitive/net6.0-android31.0/../../jar/androidx.lifecycle.lifecycle-common.jar:androidx/lifecycle/DispatchQueue.class:

It's a fresh project so I wasn't updating Xamarin.AndroidX.Work.Runtime, just added the 2.7.1.5 version. The workaround didn't help.

Directory 'obj/Debug/net7.0-android/lp/173' is from 'androidx.lifecycle.lifecycle-runtime-ktx.aar' (double-checked it with map.cache).

The problem can be easily reproduced by simply adding these two dependencies:

Xamarin.AndroidX.Camera.Camera2 v1.2.2
Xamarin.AndroidX.Preference v1.2.0.4

AndroidApp1.zip

This is usually how I do it, but it is not ideal, as you probably found out. I need to find a way to detect issue easier and even to suggest or implement fix.

by .NET Android do you mean Xamarin classic?

Can you provide csproj?

wfhm · Answer 18 · Thu Apr 27 2023 20:10:52 GMT+0800 (China Standard Time)

by .NET Android do you mean Xamarin classic?
I was talking about the one created with the default .NET Android template in Visual Studio:

Can you provide csproj?

That might be a bit complicated. The whole solution is MAUI class library based on native Android (and iOS) bindings. Bindings are then wrapped in platform-specific class libraries, and these libraries are used as dependencies in a single MAUI class library.

I was testing Android class library with both .NET Android app and MAUI app, and for MAUI it didn't work as expected.

Android library csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net7.0-android</TargetFramework>
    <SupportedOSPlatformVersion>21</SupportedOSPlatformVersion>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>
  <ItemGroup>
    <ProjectReference Include="..\PushwooshSDK.DotNet.Android.Bindings\PushwooshSDK.DotNet.Android.Bindings.csproj" />
    <ProjectReference Include="..\PushwooshSDK.DotNet.Core\PushwooshSDK.DotNet.Core.csproj" />
  </ItemGroup>
    <ItemGroup>
    <PackageReference Include="Xamarin.AndroidX.Core" Version="1.9.0.1" />
    <PackageReference Include="Xamarin.AndroidX.Arch.Core.Common" Version="2.1.0.16" />
    <PackageReference Include="Xamarin.AndroidX.Arch.Core.Runtime" Version="2.1.0.16" />
    <PackageReference Include="Xamarin.AndroidX.Activity" Version="1.6.1" />
    <PackageReference Include="Xamarin.AndroidX.Fragment" Version="1.5.5" />
    <PackageReference Include="Xamarin.AndroidX.Work.Runtime" Version="2.7.1.5" />
    <PackageReference Include="Xamarin.Firebase.Messaging" Version="123.0.8" />
    <PackageReference Include="Xamarin.Firebase.Iid" Version="121.1.0.7" />
    <PackageReference Include="Xamarin.Firebase.Common" Version="120.1.2" />
    <PackageReference Include="Xamarin.Firebase.Installations" Version="117.0.3" />
    <PackageReference Include="Xamarin.Firebase.Annotations" Version="116.1.0" />
    <PackageReference Include="Xamarin.GooglePlayServices.Basement" Version="118.1.0" />

    <PackageReference Include="Xamarin.AndroidX.SwipeRefreshLayout" Version="1.1.0.10" />
    <PackageReference Include="Xamarin.AndroidX.ConstraintLayout" Version="2.1.4.2" />
  </ItemGroup>
</Project>

Android app csproj:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net7.0-android</TargetFramework>
    <SupportedOSPlatformVersion>21</SupportedOSPlatformVersion>
    <OutputType>Exe</OutputType>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <ApplicationId>com.pushwoosh.demoapp</ApplicationId>
    <ApplicationVersion>1</ApplicationVersion>
    <ApplicationDisplayVersion>1.0</ApplicationDisplayVersion>
  </PropertyGroup>
  <ItemGroup>
    <None Remove="google-services.json" />
  </ItemGroup>
  <ItemGroup>
    <GoogleServicesJson Include="google-services.json" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="..\PushwooshSDK.DotNet.Android.Library\PushwooshSDK.DotNet.Android.Library.csproj" />
  </ItemGroup>
</Project>

MAUI app currently uses multiplatform library, so I believe its csproj is of no use to you, but I also tested it by adding nuget packages directly to the project the same way as I described here.

Please let me know if you need more detail on it.

Hi, I encountered the similar problem with: Type androidx.lifecycle.DispatchQueue is defined mutiple times.

Just update all dependencies to latest. Note: GPS-FB-MLKit or other 3rd party package might still cause issues. Namely GPS-FB-MLKit is not yet "aligned", so particular dependency could pull in problematic older packages and issue could be hit again.

How to check the dependencies that causes the error?

It is not that easy. In some cases Xamarin.AndroidX.Lifecycle.*, but in other cases combination of any could cause problems (check tipa's dependencies in this issue).

Possible Workaround

I had a similar problem, but with another packages. So, basically this thread helped to understand the root of the problem.

Problem:

Type androidx.activity.OnBackPressedDispatcherKt is defined multiple times: 
  obj/Debug/net6.0-android33.0/lp/111/jl/classes.jar:androidx/activity/OnBackPressedDispatcherKt.class, 
  obj/Debug/net6.0-android33.0/lp/143/jl/classes.jar:androidx/activity/OnBackPressedDispatcherKt.class

I went into the both paths obj/Debug/net6.0-android33.0/lp/111/jl/ and obj/Debug/net6.0-android33.0/lp/143/jl/, checked the manifests inside and installed both libraries explicitly.
In my case they are:

Xamarin.AndroidX.Activity.Ktx
Xamarin.AndroidX.Activity

I performed a quick smoke test and looks like it work, but no guarantee yet.
