WebMap not showing on Android App

[SamInwang]

I created a map on ArcGIS that I am trying to render on android devices. The WebMap shows correctly with the layer in the MapViewer as you can see but in my app it does not render anything. Just a grey background. Whats the fix?

Sam, 

Are you using the MapViewer template in AppStudio for ArcGIS version 4.1? What Android devices are you using to test this with? 

I just tested the WebMap you provided in the MapViewer template in AppStudio for ArcGIS, and it looks fine. 

Thank you,

Erwin
