I’m creating a native extension that shows a native Google Map from a Flex-based AIR application. You can watch lee brimelow’s demo to get the idea: https:\/\/plus.google.com\/110495278155587072613\/posts\/degSYVx8423<\/p>\n
I got a working demo of a native extension, just to show an Activity with some buttons, but I got stuck when I tried to show the map. Here is the exception I’m getting on setContentView(layoutID):<\/p>\n

I created a separate pure native android application for testing purpose. In this app I managed to create an activity which displays the map, this activity uses the same layout XML, the same google libraries and the same API key.<\/p>\n
Any idea’s?<\/p>\n
