I'm trying to get Google play services working in my game for android. I already have IAP's working. but when i add the "GooglePlayLicensingAsExt" extension, it breaks my build. * What went wrong: Execution failed for task ':com.byJamieFord.EvoPet:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/http/ConnectionClosedException.class Here is a look at my extensions: GooglePlayServicesExtention = version 3.0.5 GooglePlayServicesIAPExtension = version 1.0.2 GooglePlayLicensingAsExt = version 2.3.0 If i backdate the GooglePlayServicesExtention to version 3.0.1 using my svn, then it can compile, but my achievement_login returns -1. which i why i was trying to update the extension. I have the game setup on the google dev console and linked apps. I have the Google Services ID entered correctly. I tryed removing and adding the extensions many times. As far as i understand, GooglePlayLicensingAsExt is required to sign into google play services. I am running on runtime v188.8.131.52 because i have all sorts of problems with newer runtimes. I used google services many years ago on a different game in gamemaker studio 1. So i'm not new to this. Any help would be much appreciated.
