Android crashes with ActivityIndicator while starting

Hi,

on our project (and a blank test project for reproduction) the ActivityIndicator let Android Apps crash when they use minimum API Level 16 (4.1 Jelly Beans).
It's enough to put a ActivityIndicator on the blank forms project, target the API Level 16 and start.
You get the following exception:

@Xamarin.Forms Team:
Can you verify this problem?
With API Level 21 all works great but this is not a solution because many of our users have not such a modern device.

Best regards
