Processing.core.PApplet - class not found exception in Android

Question

I am trying to use PApplet libraries in my Android code. I have attached processing.jar ( which I have got from here ) in the libs folder of the project and added it to build path. But when I start the application on the device , it quickly shutdowns with class not found exception.

Following is the code snippet giving error :

public void generate(){

      bice = Bice.shadowdrawVersion();
      index = new Index(20,3,5,bice.getNumBits());
      index.generateHashes();
      imageLoader = new PApplet();


      index.reverseIndex();

      input = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + 
                "/Download/shadow");
      output = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + 
                "/Download/hashes");

      walk(input);

      String sourceName = input.toString();
      new IndexStorage(output).write(sourceName, index);


  }

And the following is the stack trace which I got from logcat

The Bice class which is giving error can be found here. I am using these files as library projects.

I have checked everything in Order and Export , followed this and few other stack overflow post. Still no luck.
