Xamarin forms Android timeout issue on StartUp - xamarin.android

Question

Hi, my android application sometimes stucks on startup. On Xamarin test cloud the failure seems like;
SetUp : System.TimeoutException : Timed out waiting...

When i tried it on Samsung s3(on xamarin test cloud) there was a StackTrace too;
java.lang.NullPointerException: key == null

I can not repeat that issue on debug mode. What can it be?
My Android OnCreate method is;
protected override void OnCreate(Bundle bundle)
{
// set the layout resources first
ToolbarResource = Resource.Layout.toolbar;
TabLayoutResource = Resource.Layout.tabs;
base.OnCreate(bundle);
Forms.Init(this, bundle);
#if ENABLE_TEST_CLOUD
Xamarin.Forms.Forms.ViewInitialized += (object sender, Xamarin.Forms.ViewInitializedEventArgs e) =>
{
if (!string.IsNullOrWhiteSpace(e.View.AutomationId))
{
e.NativeView.ContentDescription = e.View.AutomationId;
}
};
#endif
var container = new SimpleContainer();
container.Register<IDevice>(t => AndroidDevice.CurrentDevice);
container.Register<IDisplay>(t => t.Resolve<IDevice>().Display);
container.Register<IMediaPicker>(t => new MediaPicker());
container.Register<IFontManager>(t => new FontManager(t.Resolve<IDisplay>()));
container.Register<INetwork>(t => t.Resolve<IDevice>().Network);
container.Register<IJsonSerializer, MBJsonSerializer>();
container.Register<IPhoneService, PhoneService>();
container.Register<IUserDialogs>(t => UserDialogs.Instance);
if (!Resolver.IsSet)
Resolver.SetResolver(container.GetResolver());
UserDialogs.Init(this);
LoadApplication(new App());
}
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults)
{
PermissionsImplementation.Current.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
My UITest SetUp Method ;
[TestFixture(Platform.Android)]
[TestFixture(Platform.iOS)]
public class Tests
{
IApp app;
Platform platform;
public Tests(Platform platform)
{
this.platform = platform;
}
[SetUp]
public void BeforeEachTest()
{
app = AppInitializer.StartApp(platform);
}
}
Thanks in advance.
