How to use Flickr4Java on an Android device

I am trying to use Flickr4Java on an android device. One of the essential libraries for Flickr4Java is log4j. When I create a Flickr object like below:

Flickr f = new Flickr(API_KEY, API_SECRET, new REST());

      

        
        
        
      

    

I am getting the following error:

java.lang.VerifyError: org/apache;log4j/config/PropertySetter

      

        
        
        
      

    

Any suggestions on how to proceed from here?
