Xamarin.Android Cannot pull table from Azure database in Android 10 Q - azure

Question

I did read that because lack of support for Netcore 2.1 the
myItemsList = await App.MobileServiceAndroid.GetTable<MyTable>().ToListAsync();
does not currently work on Android, and there is a workaround to pass an HttpClientHandler() in the constructor of the MobileServiceClient, and so I did like this:
public static MobileServiceClient MobileServiceAndroid =
new MobileServiceClient(AppConstants.AZURE_PRODUCTION_WEB_API_URL, new HttpClientHandler());
But this is incomplete,its still not working, what exactly do I have to do to make this work, any guidance is much appreciated.

Answer 1

From my understanding, you are using a Forms/PCL project whereas the other solution was implementing this code inside their Android project.
For you, once you add using Xamarin.Android.Net; to the class, you should be able to just do this:
public static MobileServiceClient MobileServiceAndroid =
new MobileServiceClient(AppConstants.AZURE_PRODUCTION_WEB_API_URL, new AndroidClientHandler());
Most likely you might have issues getting that using statement, for that you will have to follow steps shown here, or customized for you in the following steps:
Add the Xamarin Forms project to all your projects.
Create an interface ICustomClientHandler in the Core project
using System;
using System.Net.Http;
namespace Test
{
public interface ICustomClientHandler
{
HttpClientHandler GetHandler();
}
}
Then create a CustomClientHandler in the Droid project, which will be the Android part of the dependency service that will help you retrieve the native AndroidClientHandler
using System.Net.Http;
using Xamarin.Android.Net;
using System.Runtime.CompilerServices;
using Xamarin.Forms;
using Test;
[assembly: Xamarin.Forms.Dependency(typeof(Test.Droid.CustomClientHandler))]
namespace Test.Droid
{
public class CustomClientHandler : ICustomClientHandler
{
public HttpClientHandler GetHandler()
{
return new AndroidClientHandler();
}
}
}
Implement an iOS version as well in a similar way, but it will instead return new HttpClientHandler();
Finally, use the code as shown, in your Core project:
var clientHandler = DependencyService.Get<ICustomClientHandler>().GetHandler();
public static MobileServiceClient MobileServiceAndroid =
new MobileServiceClient(AppConstants.AZURE_PRODUCTION_WEB_API_URL, clientHandler);
