Invalid dex file indices" Error in Net Maui

Question

Hi,
I get the following error when publish Android app.

[BT : 1.8.1] error : Invalid dex file indices, expecting file 'classes?.dex' but found 'classes2.dex'

Steps:

1. Create a new Maui app
2. Copy keystore file created using Xamarin from

%userprofile%\AppData\Local\Xamarin\Mono for Android\KeyAlias\KeyAlias.keystore

to solution folder Then
3. Add the following code to csproj file

 <PropertyGroup Condition="$(TargetFramework.Contains('-android')) and '$(Configuration)' == 'Release'">  
        <AndroidKeyStore>True</AndroidKeyStore>  
        <AndroidSigningKeyStore>..\KeyAlias.keystore</AndroidSigningKeyStore>  
        <AndroidSigningKeyAlias>KeyAlias</AndroidSigningKeyAlias>  
        <AndroidSigningKeyPass>P@$$w0rd</AndroidSigningKeyPass>  
        <AndroidSigningStorePass>P@$$word</AndroidSigningStorePass>  
    </PropertyGroup>  

4. Run this command in the terminal dotnet publish -c Release -f:net6.0-android

Thanks in advance

Hello,

I've tested your configuration, and it worked fine as expected.

error : Invalid dex file indices, expecting file 'classes?.dex' but found 'classes2.dex'

the ? could be a garbled code, you could try to change your system language to English and rebuild this project.

Best Regards,
