Android Xamarin在发射时形成空白屏幕

我的移动应用程序使用Xamarin表单。在初始化我的应用程序时，我想加载我的配置

我把它保存在阿卡瓦什的缓存里

当有我的启动屏幕时，我在App.xaml中的onstart方法中启动此方法

它工作得很好，但当我调用Akavache缓存时，启动屏幕变为白色。我的代码运行良好，但屏幕上没有显示任何内容

如果我请求我的api而不是使用缓存来获取配置，这是相同的行为

我还尝试在我的主要活动android部分中移动GetConfig方法，但我有相同的行为

如果我取消这个电话，一切正常

您将在下面找到输出

我认为这与GetRenderableInternalFormatInfoEntry有关：不支持的可渲染内部格式37808

我怎样才能修好它

更新

如果我在方法DependencyResolver.Resolve（）.Initialize（）之后添加调用，它会工作

方法初始化启动FirstContentPage

我的主要活动标题：我不使用splashscreen活动

[Activity(
    Label = "@string/app_name",
    Icon = "@drawable/icon",
    Theme = "@style/MyTheme.Splash",
    MainLauncher = true,
    ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize | ConfigChanges.Locale | ConfigChanges.LayoutDirection, ScreenOrientation = ScreenOrientation.Portrait
    )
]

My app.xaml.cs OnStart

protected override async void OnStart()
    {

        base.OnStart();

        await UserConfigurationManager.GetAsync(); // Make splash screen blank and no more screens appear
        await DependencyResolver.Resolve<INavigationService>().Initialize();
        
        OnResume();
    }

protectedoverride async void OnStart（）
{
base.OnStart（）；
等待UserConfigurationManager.GetAsync（）；//将启动屏幕设为空白，不再显示任何屏幕
等待DependencyResolver.Resolve（）.Initialize（）；
OnResume（）；
}

//UserConfigurationManager.GetAsync（）的详细信息

if（IsUserLoggedIn）
{
尝试
{
confsaved=wait BlobCache.UserAccount.GetObject（“loggedconfig”）；
}
抓住
{
}
}
其他的
{
尝试
{
confsaved=wait BlobCache.UserAccount.GetObject（“匿名配置”）；
}
抓住
{
}
}

请发布相关代码谢谢Jason。我更新了codeHi，如果在应用程序启动完成后使用

按钮

单击事件加载数据，它在哪里工作？

if (IsUserLoggedIn)
        {
            try
            {
                confsaved = await BlobCache.UserAccount.GetObject<UserConfigurationDto>("loggedconfig");
            }
            catch
            {
            }

        }
        else
        {
            try
            {
                confsaved = await BlobCache.UserAccount.GetObject<UserConfigurationDto>("anonymousconfig");
