问题
I'm trying to use google play services in my app.
i have referenced the library, google play serves, in both my app and BaseGameUtils and I have Unable to execute dex: Multiple dex files define Lcom/google/android/gms/ads/AdActivity; "
usually what that means is that you have two .jar files that have the same class name. My only problem is I don't know which jar files have the same classes. Also, I do not have google-play-services as a jar in my libs folder nor have i added it as an external jar in the build path menu. So all i have are two dependencies google-play-servies, and BaseGameUtils, which also uses google-play-servies as a library. So can someone tell me what this issue even means, cause i've tried everything..
here's my research to show i've tried to help myself..
Can´t use adMob api since I updated to API 19
Android Build fail - java.lang.IllegalArgumentException: already added: Lcom/google/api/client/escape/CharEscapers;
"Conversion to Dalvik format failed with error 1" on external JAR
adMob.jar library and google play service.jar not working together

Are you saying that you are referencing Google Play Services in both BaseGameUtils and your project ?
In BaseGameUtils reference Google Play Services.
In your project reference BaseGameUtils.
Then check to ensure you have got your advertising set up correctly (admobs is now in google play services , no longer a separate jar):
Multiple dex files define - Deleting extra jar file still not working. What should I do?
