Demo of the bug

#40527 is back with the version Xamarin.Android.Support.v4 24.2.1

* Actual *

using AppCompat:

var options = ActivityOptionsCompat.MakeSceneTransitionAnimation(this, imageView, "iconTransition");
var optionsBundle = options.ToBundle();

optionsBundle is null.

using no AppCompat:

var options = ActivityOptions.MakeSceneTransitionAnimation(this, imageView, "iconTransition");
var optionsBundle = options.ToBundle();

optionsBundle is not null.

* Expected *

optionsBundle should not be null in both cases.

* Reproduce * 

- download and unzip sample
- breakpoint at MainActivity.cs#45
- build & run
- inspect optionsBundle variable

If you uncomment the non app compat line and remove the app compat line and run it, you will see a nice transition of the icon.

The sample is created by using the Blank app compat template in Visual Studio. I just updated the App Compat libraries to the latest version and added the demo code.

* Version Info *

Test Device: Nexus 5x Android 7.1.1

Visual Studio 2015 Update 3

I can confirm this problem exists in version 25.1.0 of the nuget package as well.

This is still an issue.
