> When i remove the gson-1.5.jar from the project, this error goes away. I would like to use GSON in my project. What is the problem here? How can i use both GSON and GoogleAdMobAdsSDK-4.0.2.jar?
There's a copy of GSON embedded in the Google AdMob Ads SDK JAR. You should be able to simply use that by removing your own copy of GSON from your project, and it sounds like that works. Please let us know if it doesn't...
Thanks!
