For some reason, the api that I am calling in the home page, in windows is loaded when I start the app, but on mobile, I have to wait
Question
Can I do something to make it faster? Why in desktop I do not have to wait?

HomePage
public partial class HomePageViewModel : ObservableObject
{
private readonly DeviceLanguageService deviceLanguageService;
private readonly HttpService httpService;
public Command<object> OnPinMarkerClickedCommand { get; set; }
protected readonly TurbinesService _turbinesService;
public ObservableCollection<TurbinePin> Turbines => _turbinesService.TurbinePins;
public HomePageViewModel(HttpService service, DeviceLanguageService deviceLanguage, TurbinesService turbinesService)
{
deviceLanguageService = deviceLanguage;
httpService = service;
LoadNews();
_turbinesService = turbinesService;
OnPinMarkerClickedCommand = new Command<object>(OnPinMarkerClicked);
_turbinesService.GetTurbinePinsForUI(OnPinMarkerClickedCommand);
}
public ObservableCollection<Article>? NewsList { get; set; } =
[];
async void LoadNews()
{
var language = deviceLanguageService.GetDeviceCultureInfo();
var newsUrl = AppConstants.GetNewsUrl(language.TwoLetterISOLanguageName);
NewsList!.Clear();
var newsObj = await httpService.GetAsync<News>(newsUrl);
foreach (var item in newsObj!.Articles!)
{
NewsList.Add(item);
}
}
Service
public class HttpService(HttpClient httpClient, IConnectivity connectivity, ILogger<HttpService> logger)
{
public async Task<T?> GetAsync<T>(string url)
{
if (connectivity.NetworkAccess != NetworkAccess.Internet)
{
await Shell.Current.DisplayAlert("Error",
"No internet connectivity"
, "OK");
return default;
}
// Add User-Agent header
httpClient.DefaultRequestHeaders.Add
("User-Agent",
"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; Googlebot/2.1; +http://www.google.com/bot.html)");
try
{
var response =
await httpClient.GetAsync(url);
if (response.IsSuccessStatusCode)
{
var jsonData = await response.Content.ReadAsStringAsync();
var data = await response.Content.ReadFromJsonAsync<T>();
return data;
}
}
catch (Exception e)
{
logger.LogError($"Http Service: {e.Message}");
}
return default;
}
What I am trying to do is to make the desktop and mobile the same
