Do you mean you want to navigate to another app from current app ?If yes, you can use dependency injection to achieve this.

Could you please share a demo?

Navigating onto a single Contentpage works fine but another shell or even a TabbedPage is not working.

I don't quite understand what you mean by words but another shell or even a TabbedPage is not working. What's wrong or not working? Can you explain that in detail? And how can we reproduce your problem? If it is convinient for you, could you please post a basic demo so that we can try to reproduce this problem on our side?

What are the MaterialDialog and MaterialEntry? What nuget do you use in your project? If it is convinient for you, could you please post a basic demo to github or onedriver so that we can test on our side?

Sorry,we couldn't open the links of MaterialEntry and it's renderer.

There are some errors in file styles . I think there are some problems with your code. Besides, what's the code of Theme.Material3.DayNight ? If it is convinient for you , could you please post a basic demo to github or onedriver so that we can try to reproduce this problem on our side?

Hi @yusuf2 , I have not heard from you for a couple of days. Please let me know if there is anything that I can help here.

Is there any log about this problem?

Have you set the Linker to SDK Assemblies Only or Sdk and User Assemblies ? This may remove necessary libraries. So, you can try to set the Linker to None to see if this problem still exist. In addition ,does this problem happen in other apps?

How can we reproduce this problem? Could you please post the steps so that we can try to reproduce this problem on our side?

Hi @Jackson1990-7147 , one thread, one problem. For the new problem, you can create a new thread . We are all willing to help you. :)

Could you please post a basic demo so that we can help you better?

Is your new APP xamarin project? If yes, then the full reference is System.Threading.Tasks.Task , or for a using: using System.Threading.Tasks; .

Hi @Jackson1990-7147 , why would you add it to Java code? Xamarin is developed in C# and we need to code in C#.

Why do you want to add Java files to your Xamarin APP? We couldn't add a java file to our xamarin app directly . Do you want to Binding a Java Library?
