The sample app for .NET Android is running well without issues.

[sergsel]

Any progress so far? I have the same issue during build using windows.

[tuyen-vuduc]

Workaround applied to branch v11.0.0. Please check it out.

Considered closed for now.

In addition to the previous post. This issue occurred when you try to use dependences with different project. For instance when you use two project with dependences like in the example (libs and qs projects). And works good when you combine all in one project.

Workaround: Add these lines to your lib CSPROJ file.

    <Target Name="_CleanAarOutputPath" AfterTargets="_CreateAar" BeforeTargets="_IncludeAarInNuGetPackage">
        <Delete Files="$(_AarOutputPath)" />
    </Target>

[tuyen-vuduc]

@sklyarovaleksey The workaround is not that correct to use the lib as a ProjectReference, it's for packing the nuget package only :D . It's used to mentioned in this issue.

The actual workaround for this situation is to link files directly to the main .NET MAUI app project.

You can check out file MapboxMauiQs.csproj to see how I apply it.

1/ For Android

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">
   <Compile Include="..\..\libs\Mapbox.Maui\Platforms\Android\**\**\*.cs">
    <Link>Platforms\Android\Shared\%(RecursiveDir)%(Filename)%(Extension)</Link>
   </Compile>
</ItemGroup>

2/ For iOS

<ItemGroup Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">
    <Compile Include="..\..\libs\Mapbox.Maui\Platforms\iOS\**\**\*.cs">
        <Link>Platforms\iOS\Shared\%(RecursiveDir)%(Filename)%(Extension)</Link>
    </Compile>
</ItemGroup>

3/ For both

<Compile Include="..\..\libs\Mapbox.Maui\Models\**\**\*.cs">
      <Link>Shared\%(RecursiveDir)%(Filename)%(Extension)</Link>
</Compile>

If you have multiple .NET MAUI app projects, you may consider to use local Nuget package for the others. Only single project will be use this workaround.

Hey @tuyen-vuduc I'm still getting this issue when I have a second .net MAUI project on the solution. My current structure is: P1 - .NET MAUI - with all nuget package references (including MapBox.Maui version 11.4.0-alpha01) P2 - .NET MAUI project - referencing P1

During the build process, only on ANDROID, I'm getting these error messages from P2 project: Xamarin.Android.Aapt2.targets(123, 3): [APT2144] invalid file path '/Users/leonardo/Downloads/dotnet-mapbox-quickstart-main/src/quickstart/SecondProject/obj/Debug/net8.0-android/lp/196.stamp'.

It is worth noting that if I remove the reference from the P2 project, it works normally. Do I need to do any extra configuration in the P2 project?

Here's my P2 csproj:

<ItemGroup>
      <PackageReference Include="Microsoft.Maui.Controls" Version="8.0.40"/>
      <PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="8.0.40"/>
      <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="8.0.0"/>
</ItemGroup>

<ItemGroup>
  <ProjectReference Include="..\DotnetMaui.MapboxQs\DotnetMaui.MapboxQs.csproj" />
</ItemGroup>

Here's my P1 csproj:

<Project Sdk="Microsoft.NET.Sdk">
    <Import Condition="EXISTS('DotnetMaui.MapboxQs.props')" Project="DotnetMaui.MapboxQs.props" />
    <Import Condition="EXISTS('DotnetMaui.MapboxQs.targets')" Project="DotnetMaui.MapboxQs.targets" />
    <PropertyGroup>
        <TargetFrameworks>net8.0-android;net8.0-ios;</TargetFrameworks>
        <RootNamespace>DotnetMaui.MapboxQs</RootNamespace>
        <UseMaui>true</UseMaui>
        <SingleProject>true</SingleProject>
        <ImplicitUsings>enable</ImplicitUsings>
        <CreatePackage>false</CreatePackage>

        <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'ios'">11.0</SupportedOSPlatformVersion>
        <SupportedOSPlatformVersion Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'android'">21.0</SupportedOSPlatformVersion>
    </PropertyGroup>

    <PropertyGroup Condition="'$(TargetFramework)'=='net8.0-ios'">
      <ProvisioningType>manual</ProvisioningType>
      <CodesignKey>iPhone Developer</CodesignKey>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="8.0.0" />
        <PackageReference Include="Microsoft.Maui.Controls" Version="8.0.40" />
        <PackageReference Include="Mapbox.Maui" Version="11.4.0-alpha01" />
    </ItemGroup>

    <ItemGroup>
      <Folder Include="Platforms\iOS\" />
    </ItemGroup>
</Project>

@leoslima13 Add these lines to your Android lib project.

    <Target Name="_CleanAarOutputPath" AfterTargets="_CreateAar" BeforeTargets="_IncludeAarInNuGetPackage">
        <Delete Files="$(_AarOutputPath)" />
    </Target>

[leoslima13]

@tuyen-vuduc Actually I don't have any lib project, I have two .NET MAUI single projects. I tried what you sent on my two projects, but still not working. I'm sharing a link to my personal drive with the zip file of my solution (removing all my mapbox tokens) if you want try on your end. (https://drive.google.com/file/d/1u9XykbN_dlQOjKlpavF17ONE0RCU6aKq/view?usp=drive_link) Basically this project is the same as your sample, adding an extra project.

[tuyen-vuduc]

Plz slowly read and follow my instruction.

[leoslima13]

I already followed the steps you said earlier, I sent the answer with the sample project because it didn't work

[leoslima13]

Hey @tuyen-vuduc any thoughts on that? Even following your steps, I still getting the same error.

[tuyen-vuduc]

Hi @leoslima13 ,

Sorry, the actual steps were listed previously for sklyarovaleksey. Please take a look.

IMPORTANT: We cannot add project reference directly.
