I've been using the runtime sdk successfully with Xamarin and Android 6.x. I just tested the same code on a Nexus 6p device running Android 7.1 and I get this error (repeated a million times) when I launch the activity with the mapview:

UPDATE: All the ESRI samples on GitHub work with this device. However, if I simply create a new android project using visual studio's templates and replace the main activity with the exact code from the "Display a Map" sample from ESRI:
[Activity(Label = "App1", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
// Create and hold reference to the used MapView
private MapView _myMapView = new MapView();
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
Title = "Display a map";
// Create the UI, setup the control references and execute initialization
CreateLayout();
Initialize();
}
private void Initialize()
{
// Create new Map with basemap
Map myMap = new Map(Basemap.CreateImagery());
// Provide used Map to the MapView
_myMapView.Map = myMap;
}
private void CreateLayout()
{
// Create a new vertical layout for the app
var layout = new LinearLayout(this) { Orientation = Orientation.Vertical };
// Add the map view to the layout
layout.AddView(_myMapView);
// Show the layout in the app
SetContentView(layout);
}
}
Running this results in the same error on that device. So, I can't tell why the sample code works when deployed from the ESRI projects, but the very same code doesn't work in a new project.
