Question

I made an android project on Motodev (which is an eclipse plugin itself). But now when I am trying to run the same project on eclipse, the emulator gives me an error the following error:

Answer 1

That can be the result when you have compiled against a different library than you are using at runtime.

A good explanation can be had here.

Another possibility is having a duplicate class in the classpath somewhere, such as in a library jar.
