Guys I’m developing a Cross-platform App in Xamarin and I’m not able to upload https images from an api. If I perform a compilation on Windows Phone the images are normally loaded already on android no, so I ask, how to fix ?
See the pictures
Android:
UWP
I am using the following code to get the data through the api:
Home.Cs
namespace AppNewsPlay.Views
{
public partial class Home : TabbedPage
{
//private UltimasNoticias UltimasNoticias;
List<UltimasNoticias> UNoticias;
public TabbedPage Detail { get; private set; }
public Home()
{
UNoticias = new List<UltimasNoticias>();
ObterUltimasNoticias();
InitializeComponent();
}
private async void ObterUltimasNoticias()
{
// var jsonRequest = JsonConvert.SerializeObject(UNoticias);
// var httpContent = new StringContent(jsonRequest, Encoding.UTF8, "application/json");
var resp = string.Empty;
try
{
var uri = new HttpClient();
uri.BaseAddress = new Uri("http://api.newsplay.com.br");
var url = "/api/post/";
var result = await uri.GetAsync(url);
if (!result.IsSuccessStatusCode)
{
await DisplayAlert("Erro de Conexão", "Não foi possível obter as notícias do servidor, Tente novamente mais tarde!", "OK");
return;
}
resp = await result.Content.ReadAsStringAsync();
}
catch (Exception ex)
{
await DisplayAlert("Erro de Conexão com o Servidor", ex.Message, "OK");
return;
}
// transformando o retorno em objeto através do json e deserealize e retornando em lista
var UNoticias = JsonConvert.DeserializeObject<List<UltimasNoticias>>(resp);
//Adicionando os itens ao ListView na Home.xaml
UnoticiasList.ItemsSource = UNoticias;
}
private async void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
{
if(e.SelectedItem !=null)
{
var selection = e.SelectedItem as UltimasNoticias;
//DisplayAlert("Você Selecionou", selection.Post_title, "ok");
await Navigation.PushAsync(new PostView());
#region DisabledSelectionHighlighting
((ListView)sender).SelectedItem = null;
#endregion
}
}
