Error in Graphical Layout Editor

When entering the graphical layout, I get the following error:

java.lang.ClassNotFoundException: org.json.JSONException

This is a known issue with our banner. It might not work well in the graphical editor, but this shouldn't affect the actual performance of the banner, which should work fine on a device.

I recommend you test your app using an actual device. This should work just fine.
