Hi there
in my main AppShell I register routes like this
[code]
public partial class MainPage : Xamarin.Forms.Shell
{
public MainPage()
{
InitializeComponent();
RegisterRoutes(); //Register page route so we can navigate to the page
}
//Register page route so we can navigate to the page
public void RegisterRoutes()
{
Routing.RegisterRoute("showImage", typeof(ShowImagePage));
}
}
[/code]
if I first start the app so it goes to a home page I can navigate to here fine
my App.xaml.cs looks like this
[code]
public partial class App : Application
{
public App()
{
InitializeComponent();
MainPage = new MainPage();
}
protected override void OnStart()
{
// Handle when your app starts
}
protected override void OnSleep()
{
// Handle when your app sleeps
}
protected override void OnResume()
{
// Handle when your app resumes
}
//Show image that user wants to share with our app
public void ShowImage() //this method couses problems if I call this method direcly from native part b4 my app shows home page my app will crash
{
Task.Run(async () => await Shell.Current.GoToAsync("showImage")); //Go to the route we registered
}
[/code]
but in my Native part I hook insto share dialog and want to show this showImage page when user shares a file
[code]
[Activity(Label = "clip2url", Icon = "@drawable/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = @image/jpeg)] //Declaration to handle incoming files via share dialog
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
TabLayoutResource = Resource.Layout.Tabbar;
ToolbarResource = Resource.Layout.Toolbar;
base.OnCreate(savedInstanceState);
global::Xamarin.Forms.Forms.SetFlags("Shell_Experimental", "Visual_Experimental", "CollectionView_Experimental", "FastRenderers_Experimental");
Xamarin.Essentials.Platform.Init(this, savedInstanceState);
global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
//Init Xmarin Plugins
ImageCircle.Forms.Plugin.Droid.ImageCircleRenderer.Init(); //Init native Image library
//To get acsess to Xamarin Forms part
var mainForms = new App();
LoadApplication(mainForms);
//Here we tell out app what do we want to do with this share dialog data
if (Intent.Action == Intent.ActionSend)
{
mainForms.ShowImage(); //here I call my ShowImage method and I want the page to be displayed but now my home page a seperate page and I want to then navigate back to home page
}
}
public override void OnRequestPermissionsResult(int requestCode, string[] permissions, [GeneratedEnum] Android.Content.PM.Permission[] grantResults)
{
Xamarin.Essentials.Platform.OnRequestPermissionsResult(requestCode, permissions, grantResults);
base.OnRequestPermissionsResult(requestCode, permissions, grantResults);
}
}
[/code]
now if I start the app from home screen then try to share file it works fine, but if I start my app from share dialog, then my app crashes as routes for some reason don't get registered and I cannot navigate to my ShowImage page if I didn't first open my MainPage
Hope someone can shed some light to this and help me figure out whats is wrong 
Thanks
