Problem when trying to bind Google Analytics jar

Using GoogleAnalyticsAndroid V2 beta 5. Created a java binding library with google analytics jar and got it built successfully by making public one of the interfaces:

public

However in runtime I get class not found exception while looking for the class:

JNIEnv.FindClass ("com/google/analytics/tracking/android/EasyTracker", ref java_class_handle);

Are there any other attributes that need to be set in Metadata.xml document?
