title: Xamarin.Essentials SecureStorage not persisting in android after play store update
body: <p>On my Xamarin.Forms app I'd like to persist user/token info upon play store update. On iOS it does work as expected, having the data persisted even after manual uninstall/reinstall.</p>
  
  <p>I'm gone through all the initializations steps for Essentials on android in the MainActivity:</p>
  
  <pre><code>    protected override void OnCreate(Bundle savedInstanceState)
      {
          base.OnCreate(savedInstanceState);
  
          Xamarin.Essentials.Platform.Init(this, savedInstanceState);
          global::Xamarin.Forms.Forms.Init(this, savedInstanceState);
  
         [...]
      }
  
      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></pre>
  
  <p>And the data is saved like this:</p>
  
  <pre><code>await SecureStorage.SetAsync("token", user.MobileServiceAuthenticationToken);
  </code></pre>
  
  <p>How can I achieve the same behaviour as in iOS in Android?</p>
