Hi, I am trying integrate google play services in a my game. But when generate the dex I have this error:

[dx]
[dx] UNEXPECTED TOP-LEVEL EXCEPTION:

To integrate the library, I have inserted in my project.properties the path to use the library:

  1. Project target.
    target=android-13
    android.library.reference.1=…/…/…/…/cocos2d-x-es2.x/cocos2dx/platform/android/java
    android.library.reference.2=./facebook/
    android.library.reference.3=…/…/…/…/SDK/Android/sdk/extras/google/google_play_services/libproject/google-play-services_lib
    android.library.reference.4=./BaseGameUtils

any idea?

Thanks!
