Add androidx.health.connect:connect-client binding (1.1.0-rc02)

[Copilot]

HealthConnect Records Implementation Fix

• Add androidx.health.connect:connect-client (version 1.1.0-rc02) to config.json
• Add androidx.health.connect:connect-client-proto dependency to config.json (dependencyOnly)
• Add androidx.health.connect:connect-client-external-protobuf dependency to config.json (dependencyOnly)
• Run binderate to generate binding projects successfully
• Create source/androidx.health.connect/connect-client directory structure
• Add Metadata.xml to remove internal proto package from public API
• Create PublicAPI files for API tracking
• Add Xamarin.AndroidX.Health.Connect.Client.targets to remove proto PackageReference

Fix for NU1101 Error

The build was failing because connect-client-proto was referenced as a NuGet PackageReference but doesn't exist on NuGet.org yet.

Solution: Added Xamarin.AndroidX.Health.Connect.Client.targets file that:

• Gets packaged with the NuGet package
• Removes the PackageReference to the proto package at consumption time using <PackageReference Remove="..."/>
• Follows MSBuild best practices for modifying package dependencies at consumption time

This allows the binding to work without requiring a separate proto NuGet package, as the proto classes are internal implementation details.

Result

Record classes now properly implement IRecord through the Java inheritance chain:

Record (interface) → IRecord
  ↳ IntervalRecord (interface) → IIntervalRecord  
    ↳ ExerciseSessionRecord (class)

Code that previously failed now compiles:

var exerciseSession = new ExerciseSessionRecord(start, offset, end, offset, exerciseType);
client.InsertRecords([exerciseSession], null);  // Now works

This section details on the original issue you should resolve

<issue_title>HealthConnect Records do not implement IRecord</issue_title>
<issue_description>### Android framework version

net9.0-android

Affected platform version

Visual Studio 17.13.6, .NET 9

Description

I am getting an error when try to insert ExerciseSessionRecord using HealthConnectClient.InsertRecords() method, which requires an IList. I can create an ExerciseSessionRecord fine, but when adding it as a parameter to InsertRecords, it becomes red underlined with the following error:

CS0029: Cannot implicitly convert type 'AndroidX.Health.Connect.Client.Records.ExerciseSessionRecord' to 'AndroidX.Health.Connect.Client.Records.IRecord'

Steps to Reproduce

Add the Xamarin.AndroidX.Health.Connect.ConnectClient library to a Maui project.

Insert the code anywhere, as you can't run the app due to the error.
var client =HealthConnectClient.GetOrCreate(Platform.AppContext); var start = Java.Time.Instant.Parse(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")); var end = Java.Time.Instant.Parse(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")); var offset = Java.Time.ZoneOffset.From(start); var exerciseSession = new AndroidX.Health.Connect.Client.Records.ExerciseSessionRecord(start, offset, end, offset, 1); client.InsertRecords([exerciseSession], null);

Did you find any workaround?

No

Comments on the Issue (you are @copilot in this section)

@jonathanpeppers Can you either share an example project, or the version of the Xamarin.AndroidX.Health package you are using? @jonathanpeppers We normally don't even bind prerelease packages, and this one is alpha. Maybe @moljac knows some history about it.

Latest release as of now (if this is the right package):

• https://mvnrepository.com/artifact/androidx.health.connect/connect-client/1.1.0-rc02

Can I ask what feature you're using in your app? What does the package provide that you need?

I think this is something we should investigate if the package becomes stable. For now, I would be happy to help if you want to contribute with a PR.

We could also assign copilot and just see if it comes up with anything?

@jonathanpeppers You might also be able to use `JavaCast()` to `AndroidX.Health.Connect.Client.Records.IRecord` for now, such as mentioned here: * https://github.com//issues/1188#issuecomment-3077764563 @jonathanpeppers I would try to find a Java/Kotlin example of what you're trying to do and then adopt it to C#. That is the approach I've taken since Xamarin days.

Alternatively, you can use the "slim binding" idea and write a small Java/Kotlin project with a simple interface for C# to call into:

• https://devblogs.microsoft.com/dotnet/native-library-interop-dotnet-maui/

Some of that article is out of date, but there is an AndroidGradleProject item group that is directly in the product now.

If there are missing C# APIs in the bindings you need, let us know here, and we'll working on addressing issues with upvotes and activity. Thanks!</comment_new>

Fixed in commit a97dd14. Added merge.targets file that embeds the proto JAR files directly into the binding and removes the PackageReference to the non-existent Proto package.

@moljac @sheiksyedm do you have any suggestions to fix this manually?

What it did in a97dd14, doesn't seem right.

@moljac @sheiksyedm do you have any suggestions to fix this manually?

I need to check.

What it did in a97dd14, doesn't seem right.

No. This is completely wrong. It will take quite a long time for Copilot to have good RAG or be fine tuned for Android bindings and even worse for binderator based bindings process. There is simply not enough samples for training.

I started health bindings while ago, but it was not priority, because it was in preview and for my side projects I needed it for - there was simply no free time for those.

IIRC there was one tougher aar that had tons of errors, but I cannot recall.

I must check my repo and find backups from 9-12 months ago...

Reverted a97dd14 in commit 95c85f3. Instead of using merge.targets (which modifies the build), I added a Xamarin.AndroidX.Health.Connect.Client.targets file that gets packaged with the NuGet and removes the proto PackageReference at consumption time. This is the correct MSBuild pattern for modifying package dependencies.

@jonathanpeppers

My hands were tight, because of our rules - no previews, so in most cases we used to bind and publish from branches.

I could add those (and few more I think it would make sense to add) to config.json and everything will be easier in the future. For Google having previews and previews als [transitive] dependencies is OK, so IMO that should be OK for us too. I didn't change my mind in last few years. And it would make bindings a lot easier.
