java.lang.NoClassDefFoundError

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a new Android project
2. Add tween-engine-api.jar to the project's build path
3. create a TweenManager object in the main activity

What is the expected output? What do you see instead?

I'm having a java.lang.NoClassDefFoundError: 
aurelienribon.tweenengine.TweenManager during runtime, although eclipse
found all the Tween classes in the autocomplete.

What version of the product are you using? On what operating system?
tween-emgine-api version 6.3.2. I'm using android 2.1, but i also gives me 
error on other versions

Please provide any additional information below.
I weird because there is the TweenManager.class in the jar file and it is 
already in the build path. I'm try it by inserting the source code instead of 
the jar, and it works flawlessly.

Woups, sorry for the very late answer, I completely missed the issue.
This behavior is typical of eclipse, and is not related to the engine. I only 
provide a set of classes and source code, the issue cannot come from this side. 
Try to clean the project, and sometimes to restart eclipse. This IDE is a 
strange beast :)

I hope you fixed your issue since you posted it...

It was an ADT issue on Eclipse after all, the last update only accept jar files 
to be on "libs" folder. Sorry for the false issue.

I tried cleaning project and even restarting several times but still no work on 
Android starter. when I ran on desktop starter, it works. How come it happened 
that the tween engine gone wrong?
