Error APT2260 when reference to Binding project

[bulubuloa]

Android application type

.NET Android (net7.0-android, net8.0-android, etc.)

Affected platform version

VSMac 17.6.11

Description

• I'm trying to migrate a Binding project from Xamarin to .NET.

1. Create a binding project following the Microsoft documentation. Modify some things like removing nodes in Metadata.xml and successfully build.
2. Create a new sample .NET-Android project and reference the DLL or project from step 1.
3. Try to build the sample project. I encountered several issues (APT2260) as shown below:.
4. The sample project and binding project can build successfully individually but fail when referenced together.

• Binding project and sample project are using the same TargetFramework/SupportedOSPlatformVersion

I appreciate any help.

Steps to Reproduce

1. Create binding project -> Build OK
2. Create sample project (default template) -> Build OK
3. Reference Binding project to sample -> Build Sample -> FAILED

@dellis1972 @jonathanpeppers

A spot check shows the referenced attributes exist in the values.xml in the bound .aar:

This appears to be either a resource or building issue.

[bulubuloa]

I found that those custom attributes do not define the format type, and it could not build for Xamarin (I tested on other .net android). Any suggestion to resolved @jonathanpeppers @dellis1972

Hi @bulubuloa
We are facing a similar issue, did you find a workaround for this?

[dellis1972]

Looks like it has to be fixed upstream via BlinkID/blinkid-xamarin#74 (comment)

[bulubuloa]

@NcaDev1 Unfortunately, we still have not dealt with this

[NcaDev1]

@bulubuloa I could fix our error by adding all required dependencies of the Android library as NuGet packages to the binding project.
