ANDROID: My MapView is only displaying grid lines. (I have checked around other boards fruitlessly)

Issue

When I load my MapView while debugging my application, the MapView only displays the greyis grid lines. I have tried:

1. Getting an API key with my debug signing certificate and including it in my MapView by using a .xml file that gets inflated

2. Checking to see that maps work in other applications (it does).

3. Cleaning the project and regenerating R.

EDIT:

1. Added uses INTERNET permission

Thanks in advance for any help.

Solution

It has started working randomly So I guess the problem is resolved. Thanks to everyone that tried to help. I will post back in here if it breaks again.
