Android Question .JAR and RES of Goole Play Services for wrapper

I am making a wrapper for B4A and I need Google Play Services library in my project. I have added google-play-services.jar to @BA.DependsOn of my library , but is it really needed to write it in XML file of my wrapper if I also add attribute in my B4A application : #AdditionalRes: C:\Android\extras\google\google_play_services\libproject\google-play-services_lib\res, com.google.android.gms and have also a copy of google-play-services.jar in B4A library folder ?

Thanks
