Infinite Test Loop and Build Errors After Adding BarcodeScanner.Mobile.Maui and Xamarin.AndroidX.Fragment.Ktx

[PrekshyaDali]

Hi, I am experiencing a couple of issues after adding the BarcodeScanner.Mobile.Maui package to my project:

** Build Errors (Java Errors):**
MSBUILD : java.exe error JAVA0000: Error in obj\Debug\net8.0-android\lp\145\jl\classes.jar:androidx/activity/ActivityViewModelLazyKt$viewModels$1.class:
MSBUILD : java.exe error JAVA0000: Type androidx.activity.ActivityViewModelLazyKt$viewModels$1 is defined multiple times: obj\Debug\net8.0-android\lp\145\jl\classes.jar:androidx/activity/ActivityViewModelLazyKt$viewModels$1.class, obj\Debug\net8.0-android\lp\179\jl\classes.jar:androidx/activity/ActivityViewModelLazyKt$viewModels$1.class

The issue is resolved by adding the Xamarin.AndroidX.Fragment.Ktx package:

However, this approach seems to introduce other problems.

2. Infinite Loop When Running Tests:
   After resolving the build issue with Xamarin.AndroidX.Fragment.Ktx, the tests in my project are now running infinitely in a loop when executed.

I’ve tried debugging, but the tests never finish executing. I am not sure if this is caused by the AndroidX dependency conflict or if there is another underlying issue.

Environment:

• .NET MAUI version: .NET8
• BarcodeScanner.Mobile.Maui version: [version number]
• Xamarin.AndroidX.Fragment.Ktx version: 1.7.0.1
• Operating System: Windows
• IDE: Visual Studio

Steps to Reproduce:
Create a new .NET MAUI project.
Add the BarcodeScanner.Mobile.Maui package.
Build the project, encounter Java-related build errors.
Add Xamarin.AndroidX.Fragment.Ktx to resolve the build error.
Attempt to run tests – they start but run infinitely without completing.

Target Frameworks:
Main Project: net8.0-ios;net8.0-android;net8.0;
Test Project: net8.0

Expected Behavior:

• Successful build without Java errors after adding BarcodeScanner.Mobile.Maui.
• Tests should run and complete as expected.

Actual Behavior:

• Java build errors are resolved by adding Xamarin.AndroidX.Fragment.Ktx.
• Tests run infinitely without completing.

What I’ve Tried:

• Cleaned and rebuilt the project.
• Checked for dependency conflicts and tried updating/reinstalling packages.
• Checked for issues with the test project setup.

Additional Notes: I would appreciate guidance on resolving the infinite test loop issue and whether there is a recommended way to avoid using Xamarin.AndroidX.Fragment.Ktx or an alternative to prevent the dependency conflict.
