Xamarin Forms / Android map app在模拟器上运行，但在物理设备上崩溃

Question

I'm trying to create a simple map app with the ArcGIS Runtime SDK for Xamarin, with the Xamarin.Forms option, so far with just the Android version (don't have access to a Mac for iOS yet). I can run the app just fine on an emulator. But when I deploy it to my physical Android tablet (Nexus 7 w/5.0.1), the app crashes when it goes to display the map. I've even packaged it up and had a friend deploy it to their new Samsung phone and it also crashes there.

Code is extremely simple. Here's the entire main method in the shared code ContentPage class (the ArcGIS SDK only supports the shared code approach):

InitializeComponent ();

myMap = new Map(Basemap.CreateImagery());

// MyMapView is in the XAML markup
MyMapView.Map = myMap;

The app crashes with the "Unfortunately (app name) has stopped". In Visual Studio, the output includes this:

Java.Lang.IllegalArgumentException: No configs match configSpec

Based on other online posts for the configSpec error message, this would seem to be an OpenGL issue. But the physical devices appear to support the required OpenGL ES 2.0. I'm also able to run a little app with the sample code at https://developer.xamarin.com/api/type/Xamarin.Forms.OpenGLView/

I've also run both the ESRI Xamarin.Forms samples and the Xamarin.Android samples on the emulator and devices, with the same result. Any ideas as to cause here?

如果是opengl错误，则可能检查设备上的开发人员选项，并确保在那里启用了opengl 2.0。
