Is it possible to open another app in my app with xamarin.form?

I'm new in the channel; I recently started with xamarin.form for cross-plattform apps.

I've been stuck with a question for a few days. I would like to know if there is a method that allow me to open a third-party application by my app or it's necessary to implement this function for each platform in a different way.

Precisely, I would like to know if there is a method similar to that provided by IFrame in UIWebview for web pages to open third-party apps in my app without launching the second app sending my app in background?

This works very well for me.

In xamarin forms in the layout file put this button

<Button Text="Open Facebook"
            Margin="20"
            Clicked="Button_Clicked"
            VerticalOptions="CenterAndExpand"
            HorizontalOptions="FillAndExpand"
            BackgroundColor="#1b89c0"
            TextColor="White"/>

Next the .cs of this layout, I have the button and implementing the dependency service.

async void Button_Clicked(System.Object sender, System.EventArgs e)
    {
        DependencyService.Get<IBackgroundDependency>().ExecuteCommand();
    }

The next step is make a new interface

public interface IBackgroundDependency
{
    void ExecuteCommand();
}

and finish with the class inside the android directory.

[assembly: Dependency(typeof(BackgroundDependency_Android))]
namespace AbrirApp.Droid{
public class BackgroundDependency_Android : Java.Lang.Object, IBackgroundDependency
{

    public void ExecuteCommand()
    {

        Intent intent = new Intent();
        intent.SetFlags(ActivityFlags.NewTask);
        intent.SetComponent(new ComponentName("com.example.averesta", "com.example.averesta.MainActivity"));
        Android.App.Application.Context.StartActivity(intent);

    }

  }
}

new ComponentName("Package name", "Package name activity")

In my case the main application is in xamarin, and the invoked application is in android studio.

you can try this;

 private async void Button_OnClicked(object sender, EventArgs e)
            {  //You need to change your app package address which you want to open with button. Example: "com.microsoft.office.officelens"
                Intent intent = new Intent();
                intent.SetComponent(new ComponentName("com.package.address", "com.package.address.MainActivity")); 
                Android.App.Application.Context.StartActivity(intent);
            }

Also, if you want to check user downloaded or didn't download this app;

public string facebookApp;



public async Task ShowAlert()
        {
            this.facebookApp = "https://play.google.com/store/apps/details?id=com.facebook.katana&hl=tr";
            var action = await DisplayAlert("Warning", "Please download facebook app first.", "Okay", "Cancel");
            if (action)
            {
                Device.OpenUri(new Uri(this.facebookApp));
            }
        }

private async void Button_OnClicked(object sender, EventArgs e)
           {  
                try
                {
                    Intent intent = new Intent();
                    intent.SetComponent(new ComponentName("com.package.address", "com.package.address.MainActivity")); 
                    Android.App.Application.Context.StartActivity(intent);
                }
                catch (Exception ex)
                {
                    ShowAlert();
                }
           }

So, in this case; if the user didn't download xApp(facebook, twitter, etc.) before, he/she will get a warning. If they click Okay on DisplayAlert, the program will send them to Google Play link.
