HealthConnect Records do not implement IRecord

[adam4fx]

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<IRecord>. 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

Can you either share an example project, or the version of the Xamarin.AndroidX.Health package you are using?

[adam4fx]

The version of Xamarin.AndroidX.Health is 1.1.0-alpha07.

I created a new repo here, its just a new MAUI project, with the code in the MainActivity. I suspect ExerciseSessionRecord, and the other Records (e.g. HeartRateRecord, SpeedRecord) are possibly supposed to implement IRecord. The original android docs show ExerciseSessionRecord implements Record.

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?

You might also be able to use JavaCast<T>() to AndroidX.Health.Connect.Client.Records.IRecord for now, such as mentioned here:

I am developing an app that connects to fitness equipment (treadmill, bike etc.) and we're looking to send the workout data to Google Fit, but those APIs say not to use them as its being replaced with Health Connect and to implement that instead.

I have never contributed with a PR before, so I wouldn't even know where to start.

I will give the JavaCast<T>() a try.

[adam4fx]

I have a problem with some methods requiring a IContinuous parameter.

HealthConnectClient.PermissionController.GetGrantedPermissions(IContinuous p0)

and the

HealthConnectClient.InsertReceord(IList<IRecord>, IContinuous p1)

Do you know off the top of your head how I may be able to deal with these, or will I need to wait to a later date to implement this?

Thanks for your help so far.

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!
