How to open or access data from an Android Fragment from Xamarin Forms code?

I have an Android fragment that has a function that outputs a hexadecimal string. I need some way of either opening this fragment from Xamarin Forms code, or sending the string to my Xamarin Forms page.

I have tried to implement a MessagingCenter script that would send the string to my Xamarin Forms code, but my issue is that I cannot figure out how to create an intent from Forms that would start the Android Fragment. What I need is for some way that when a button is pressed in forms, it would either call the Fragment or open an android page with the fragment.

Xamarin Forms:

private void OnGenerate(object sender, EventArgs e)
{
    MessagingCenter.Subscribe<App, string>(App.Current, "OpenPage", (snd, arg) =>
    {
        Device.BeginInvokeOnMainThread(() => {
            tagLabel.Text = arg;
        });
    });
}

Why dont you just use the Preferences API? You just add the nuget package to your Core and Android projects.

Then in your Android project, you store the value

Preferences.Set("my_key", "my_value");

and in your Core project, you can just get that value using

var myValue = Preferences.Get("my_key", "default_value");
