Web API Connection Failure In Xamarin Android

Deepak Verma

I have published my Web API on IIS and when I am consuming it in my Xamarin Android App, it is throwing error i.e., Connection Failure. I have written this code:-

public HotDogRepository()

{

Task.Run(() => this.LoadDataAsync(url)).Wait();

}

private async Task LoadDataAsync(string uri)

{

try

{

if (hotDogGroups != null)

{

string responseJsonString = null;

using (var httpClient = new HttpClient())

{

Task getResponse = httpClient.GetAsync(uri);

HttpResponseMessage response = await getResponse;

responseJsonString = response.Content.ReadAsStringAsync().Result;

hotDogGroups = JsonConvert.DeserializeObject >(responseJsonString);

}

catch (Exception ex)

{

throw;

}

HotDogRepository Class Method:-
public HotDogRepository()
{
   try
   {
      GetHotDogGroupsList();
   }
   catch (Exception ex)
   {
      throw;
   }
}
public void GetHotDogGroupsList()
{
   try
   {
      List list = new List();
      using (ApiHandler api = new ApiHandler())
      {
         var response = api.GetAsync("api/HotDog/GetHotDogGroups").Result;//getting the          customer addresses list
         var jsonResult = response.Content.ReadAsStringAsync().Result;
         if (response.IsSuccessStatusCode)
         {
            hotDogGroups =(List)Newtonsoft.Json.JsonConvert.DeserializeObject(jsonResult, typeof(List));
         }
      }
   }
   catch (Exception ex)
   {
      throw;
   }
}
API Handler Class:-
public class ApiHandler : HttpClient
{
   public ApiHandler()
   {
      string baseAddress = "http://***.***.*.***:83/"; //Always use your machine IP, if you have published your Web API on local IIS server
      BaseAddress = new Uri(baseAddress);
   }
}

HttpClientHelper apiclients = new HttpClientHelper(url);

var userinfo = await apiclients.Getme();

public async Task> Get()

{

using (var httpClient = new HttpClient())

{

var endpoint = _endpoint;

var accessToken = _accesstoken;

httpClient.DefaultRequestHeaders.Accept.Clear();

httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

if (accessToken != "")

{

httpClient.DefaultRequestHeaders.Add("Authorization", "JWT " + accessToken);

}

var response = await httpClient.GetAsync(endpoint, HttpCompletionOption.ResponseHeadersRead).ConfigureAwait(false);

var res = (response.Content.ReadAsStringAsync().Result).ToString();

return Newtonsoft.Json.JsonConvert.DeserializeObject>(response.Content.ReadAsStringAsync().Result);

}

}
