title: com.google.android.maps does not exist strange error
body: <p>I can't build my android project, it says that com.google.android.maps does not exist. It is way strange because in my project in libraries I have them. I rebuild the build.xml. The import com.google.android.maps.MapActivity; is not marked as error. What should I do?</p>
