this is an error that I get when running my application on android.

Does anybody know how to solve this error ?
thank you in advance :)

How silly I am!!!. I doestn’t mean to pump the topic. The problem is that I use jme3-android.jar in stable version and it not compatible with the other jar in nighty version anymore. So this is the reason why this problem occur.

I’m getting the same problem but I’m fairly sure (I just checked) I’m using the nightly libraries for everything. Could this be a problem introduced in a recent nightly build?

I though that at first too. but after I replace jme-android.jar from nigthy version 17/03/2012 its work just fine:-)
