4 years ago OK, i've done it.
For future reader reference, here's how you do it: Add a new Android Binding project to solution. Add the polar-ble-sdk.aar to JARS folder, and set build action to LibraryProjectZip Add a new class file named AttributeOperation.cs to additions folder and set this to its content: using Java.Lang; namespace Com.Androidcommunications.Polar.Enpoints.Ble.Common.Attribute { public partial class AttributeOperation : Object, IComparable { int IComparable.CompareTo(Object obj) { return CompareTo((AttributeOperation)obj); } } }
Add two nugget references: a) Naxam.RxAndroid.Droid - b) Naxam.RxJava2.Droid
Build the project, and reference this project on your Xamarin.Android project.
And thats it for mapping the native android library to you xamarin android project.
Now for some code samples on how to interface with a polar sensor, this is what i've used: (Please, have in mind that this my first approach on this subject, and this code is only in early stage of development, thus its only saving a string representation of the data received on a List of strings)
`using System; using System.Collections.Generic; using System.Linq; using System.Text;

api = PolarBleApiDefaultImpl.DefaultImplementation(MainActivity.Instance, PolarBleApi.FeatureBatteryInfo | PolarBleApi.FeatureDeviceInfo | PolarBleApi.FeatureHr);
api.SetApiCallback(new PolarBleApiCallbackImpl(Log));
var autoconnect = api.AutoConnectToDevice(-50, "180D", null).Subscribe(new RxAction(() => { Log.Add("Concluido"); }), new RxConsumer<Java.Lang.Throwable>((e) => { Log.Add($"Error: {e}"); }));
//var scan = api.SearchForDevice(new Consumer(Log));

I have not tampered with the IOS mapping yet.

Hi Polar Developers, Have any of you been able to create necessary bindings for the native libs on Android and iOS projects in a Xamarin / Xamarin Forms solution???
I've been trying to integrate Polar Sensors Data into my xamarin forms application and i wonder if someone already done this before?
