At first I should say that I have read all similar questions and they can not solve my problem .
I have a Splash Screen in my Xamarin Forms project and check the credentials in it and then in each condition start Main Activity with different parameter toward the condition . When Splash Screen finish it's work and disappear , the app show a black screen about 10 seconds and then main page is showing
this is my Splash :
[Activity(Theme = "@style/MainTheme.Splash",
MainLauncher = true,
NoHistory = true,
ScreenOrientation = ScreenOrientation.Portrait)]
public class SplashActivity : Activity
{
static readonly string TAG = "X:" + typeof(SplashActivity).Name;
public override void OnCreate(Bundle savedInstanceState, PersistableBundle persistentState)
{
base.OnCreate(savedInstanceState, persistentState);
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
Log.Debug(TAG, "SplashActivity.OnCreate");
}
protected override void OnResume()
{
base.OnResume();
Task startupWork = new Task(() => { SimulateStartup(); });
startupWork.Start();
}
async void SimulateStartup()
{
Some Code ...
InvokeMainActivity("SomeType");
}
private void InvokeMainActivity(string type)
{
Intent _activity = new Intent(Application.Context, typeof(MainActivity));
_activity.PutExtra("Key", type);
_activity.AddFlags(ActivityFlags.NoAnimation);
StartActivity(_activity);
}
and this is my MainActivity :
[Activity(Label = "@string/app_name",
Icon = "@drawable/icon",
Theme = "@style/MainTheme",
MainLauncher = false,
LaunchMode = LaunchMode.SingleTask,
ConfigurationChanges = ConfigChanges.Orientation | ConfigChanges.ScreenSize | ConfigChanges.Locale | ConfigChanges.LayoutDirection)
]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override async void OnCreate(Bundle bundle)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(bundle);
Xamarin.Essentials.Platform.Init(this, bundle);
Rg.Plugins.Popup.Popup.Init(this, bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
FFImageLoading.Forms.Platform.CachedImageRenderer.Init(enableFastRenderer: true);
Window.DecorView.LayoutDirection = LayoutDirection.Rtl;
string type = Intent.GetStringExtra("SomeType");
LoadApplication(new App(type));
}
}
How can I fix this ?
<item name="android:windowIsTranslucent">true</item>
in your androidstyles.xml
, it will not have black sreen when you switch page. – Leon Lu - MSFT
