passing string data from Android MainActivity to PCL TabbedPage xamarin.form
<p>Hello everyone Good Day how do I pass string value or data from Android MainActivity to PCL TabbedPage?</p>

<p>MainActivity.cs</p>

<pre><code> using System;
 using Android.App;
 using Android.Content;
 using Android.Content.PM;
 using Android.Runtime;
 using Android.OS;
 using Android.Telephony;
 using Xamarin.Forms;

   namespace NegDrClient.Droid
   {
   [Activity (Label = "Neg Client", Icon = "@drawable/logo", MainLauncher = true, ScreenOrientation = ScreenOrientation.Portrait)]
   public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
   {

       protected override void OnCreate (Bundle bundle)
       {
           base.OnCreate (bundle);
           global::Xamarin.Forms.Forms.Init (this, bundle);
           global::ZXing.Net.Mobile.Forms.Android.Platform.Init ();
           LoadApplication (new App ());
        }

       public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults)
       {
           global::ZXing.Net.Mobile.Forms.Android.PermissionsHandler.OnRequestPermissionsResult (requestCode, permissions, grantResults);           
       }

       public string GetNumber()
       {
          TelephonyManager telephonyManager =
            (TelephonyManager) Forms.Context.GetSystemService(Android.Content.Context.TelecomService);
          var number = telephonyManager.Line1Number;
          return number.ToString(); 
       }
     }
   }
</code></pre>

<p>I need to call the GetNumber() method so I can assign it to my login entry, Thanks. </p>
