Cocos2d-x game crashes on Android Emulator

Hi my app is able to run on a real device but I'm having trouble running it on the android emulator. It crashes on startup. I have tried using x86 architecture along with ARM architecture and am getting the same results. I have Use Host Gpu checked and am running Android 4.4.2. Here is my logcat output:

It's crashing in findClass Java JNI code related to AdMob. Make sure you have added jar file in your Project -> Properties -> Java Build Path -> Libraries and if it's already added then make sure it must be checked in your Project -> Properties -> Java Build Path -> Order and Export
