Xamarin App Android 上的输入调度超时错误

Question

我对 Xamarin Android 有疑问。

使用我的应用程序的几个 Android 用户在三星设备上遇到 ANR 错误，9/10。我尝试在我们的设备上复制该问题，但没有成功（Samsung S9 和 A3 2016）。

主页似乎可以正常工作；它使用 do while 语句，但我不认为是有影响的（见下面的代码）。 该错误发生在登录阶段，同时执行一些 http 请求。

首页动画：

private async Task AnimazioneTiles()
        {
            try
            {
                do
                {
                    foreach (VMTileWelcome tile in tilesWelcome)
                    {

                        tileImage.Source = tile.ImageSource;
                        tileTitle.Text = tile.Title;
                        tileSubTitile.Text = tile.SubTitle;

                        await stackContenitoreTiles.FadeTo(1, 400, Easing.Linear);
                        await Task.Delay(5000);
                        await stackContenitoreTiles.FadeTo(0, 400, Easing.Linear);
                        await Task.Delay(500);

                    }

                }
                while (true);
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine($"Errore animazione! {ex}");
            }
        }

Http 请求：

HttpOperationResponse<t> result = await Task.Run(async () => await this.PostAsync<t>(endPoint, content));

ANR Google 控制台：

有人对 xamarin 有同样的问题吗？
