Type androidx.collection.ArrayMapKt is defined multiple times

[Calichi]

When debugging on a physical Android device from VSCode, I get the following exception.

Exception:

Type androidx.collection.ArrayMapKt is defined multiple times

Steps to reproduce the behavior:

1. Install the package plugin.LocalNotification_v11.1.4.
2. Start debugging the project

Additional information

I am debugging a MAUI app intended for Android on a physical mobile device with OS (Android 10).

Version 10.1.8 of the mentioned package plugin.LocalNotification does not produce this issue and integrates correctly.

I am also having this issue when trying to build / debug a project to a android 14.0 API 34 android emulator build. I am running plugin v 11.1.4

Downgrading to 11.1.3 fixed the compilation issues.

Hello,
I had the same problem here, I'm using .NET 8 and Maui Blazor, I managed to solve it by manually installing these packages in their latest versions:

 Xamarin.AndroidX.Collection = 1.4.3.1
 Xamarin.AndroidX.Collection.Jvm = 1.4.3.1
 Xamarin.AndroidX.Collection.Ktx = 1.4.3.1
 Xamarin.AndroidX.Preference = 1.2.1.10

@Calichi Hi, I had the same issue as you.

But I need the 11.1.4 because of this issue: #465

My solution works when I installed this Nugets.

<PackageReference Include="Xamarin.AndroidX.Collection" Version="1.4.0.5"/>
<PackageReference Include="Xamarin.AndroidX.Collection.Jvm" Version="1.4.0.5"/>
<PackageReference Include="Xamarin.AndroidX.Collection.Ktx" Version="1.4.0.5"/>
<PackageReference Include="Xamarin.AndroidX.Fragment.Ktx" Version="1.7.0.2" />
<PackageReference Include="Xamarin.AndroidX.Lifecycle.LiveData.Core" Version="2.7.0.4" />
<PackageReference Include="Xamarin.AndroidX.Activity.Ktx" Version="1.9.0.3" />

THIS NUGET FAILS RIGHT OUT THE BOX ON A FRESH INSTALL.
STEPS TO REPRODUCE
1 - Create Brand New Maui App, (do not select the version with multiple projects per platform).
2 - Install [Plugin.LocalNotification] nuget
3 - Build:
