Question

我在Xamarin Android上遇到问题。

使用我的应用的多个Android用户在三星设备上收到ANR错误（9/10）。我试图在我们的设备上复制问题，但没有成功（三星S9和A3 2016）。

主页页面似乎可以正常工作；它使用do while语句，但我不认为是有影响力的（请参见下面的代码）。在执行某些http请求时，在登录阶段会发生错误。

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：

输入调度超时（等待发送非键事件，因为触摸的窗口尚未完成处理500.0ms之前传送给它的某些输入事件。等待队列长度：14.等待队列头年龄：61840.6ms。）

有人对xamarin有相同的问题吗？
