It looks like MapBackMarkActivity is an inner class, the upperCase "M" in the FQN points to that (mapBack.*M*apback.MapBackMarkActivity), if thats the case I don't now if dalvik can handle activities as inner classes, you can try "promoting" MapBackMarkActivity to a normal class.
If it's not, it's MapBackMarkActivity a public class? it has a default constructor? Any weird static initialization? If that's not the case, check for duplicated jars in your build.
