Android: Couldn't find import for class java.util.ArrayList in aidl file

Question

I currently have a remote service which gets the users current location (this is all working fine). I now want to be able to get the users current location then add a to a list of previous locations. Here is my aidl file, where i'm having a problem :

import android.location.Location;
import java.util.ArrayList; //error line: couldn't find import for class java.util.ArrayList

interface ILocationService {
    Location getCurrentLocation();
    ArrayList<Location> getAllLocations();
}

Any help would be much appreciated. Thanks.

Is there a particular reason the return type isn't `java.util.List`? — Matt Ball, Jun 15 '11 at 15:30
Nope, changing ArrayList to just List fixed the error. Thanks! — JDx, Jun 15 '11 at 15:34

(As per my comment, which apparently fixed the problem)

Use java.util.List<Location> instead of java.util.ArrayList<Location>.

Another win for coding against interfaces rather than implementations! – Matt Ball Jun 15 '11 at 15:38
