I\'ve used the Maps APIs many times before and not had this problem, but I\'ve clearly done something wrong with this IntelliJ project. Under Settings->SDKs I have specified
So to get the Google (Maps etc) APIs working in IntelliJ:
Under File->Project Structure->SDKs add an item for the platform level you're targetted. Under the classpath tab add a reference to the top of the android SDKs folder, and use the Build Target menu to specify which platform to target.
Under Settings->Project Structure->Modules->Dependencies select the SDK version from the "Module SDK" list
If you need to target the Google (Maps etc) APIs then under Settings->Project Structure->SDKs->Classpath make sure you ALSO add a reference the .jar file for the Google APIs for that platform version (e.g. addons/addon_google_apis_google_inc_8/libs/maps.jar
