Verify Error on android 4.0.4

Hi:

I have an app that uses radaee and it throws an error in android 4.0.4

10-02 12:57:39.641: E/AndroidRuntime(4061): FATAL EXCEPTION: main

I´ve checked and I have com.radaee.pfdex.view.jar on libs. I tried changing the tarjet, cleaning, rebuilding. I don´t know which version of the library I have but it´s recent (less than 6 months ago). What can I do?

thanks

Can you please try with the demo project alone... to try to isolate the problem
