Xamarin MonoAndroid Azure mobile service InsertAsync

Question

I'm using Xamarin for Android and have added the azure mobile services componenet.

I'm trying to create the todo list application like ( https://github.com/xamarin/azure-mobile-services )

I connect to the mobile service like this:

public static string mobileServiceUrl = "http://MyMoblieService.azure-mobile.net/.azure-mobile.net/";
public static string mobileServiceAppKey = "MyAppKey";

private static readonly MobileServiceClient MobileService =
            new MobileServiceClient(mobileServiceUrl, mobileServiceAppKey);

this.adapter = new TodoAdapter(MobileService.GetTable<Item>(), this);

I use the adapte Insert function to insert data into the table

   public void Insert(Item item)
   {
    IsUpdating = true;
    this.items.Add(item);
    NotifyDataSetChanged();

    this.table.InsertAsync(item).ContinueWith(t =>
    {
        if (t.IsFaulted)
        {
            this.items.Remove(item);
            NotifyDataSetChanged();
        }

        IsUpdating = false;
    }, scheduler);
}

and everytime I get t.IsFaulted = true , while debuging when I dig in t.Exception I find Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException

I would be glad to supply the rest of the code if needed.

Edited The only way I could get the exception level is by getting the details from the watch window while debugging. The exception has 2 attributes: Request&Response The request: - Request {Microsoft.WindowsAzure.MobileServices.ServiceFilterRequest} Microsoft.WindowsAzure.MobileServices.ServiceFilterRequest Accept "application/json" string Content "{\\"text\\": \\"tyu\\", \\"complete\\": false}" string ContentType "application/json" string - Headers Count=2 System.Collections.Generic.Dictionary - Items {System.Collections.Generic.KeyValuePair[2]} System.Collections.Generic.KeyValuePair[] - [0] {System.Collections.Generic.KeyValuePair} System.Collections.Generic.KeyValuePair Key "X-ZUMO-INSTALLATION-ID" string Value "17b22eec-edd2-4a15-a37f-d4c5d87e4e8e" string + Non-public members

Answer 1

As we discussed in the comments: the URL you're passing to the MobileServiceClient constructor is incorrect. The 'Not Found' response made me look in the URL which you have:

public static string mobileServiceUrl =
    "http://MyMoblieService.azure-mobile.net/.azure-mobile.net/";

And that's incorrect. It should be as shown below:

public static string mobileServiceUrl =
    "http://MyMoblieService.azure-mobile.net/";
