Depuración de Android: java.lang.ArrayIndexOutOfBoundsException

Question

Recibí este seguimiento de pila hoy y tengo un problema para encontrar el problema.

Me parece que el problema está en este fragmento de código. Pero es tan pequeño y simple, simplemente no lo estoy viendo. ¿Algunas ideas?

@Override 
    public boolean dispatchTouchEvent(MotionEvent me){ 
     this.detector.onTouchEvent(me); 
     return super.dispatchTouchEvent(me); 
    } 

    public void onSwipe(int direction) { 
     String str = ""; 

     switch (direction) { 

     case SimpleGestureFilter.SWIPE_RIGHT : wv.loadUrl("javascript:slideRight()"); 
                break; 
     case SimpleGestureFilter.SWIPE_LEFT : wv.loadUrl("javascript:slideLeft()"); 
                break; 
     case SimpleGestureFilter.SWIPE_DOWN : wv.loadUrl("javascript:slideDown()"); 
                break; 
     case SimpleGestureFilter.SWIPE_UP : wv.loadUrl("javascript:slideUp()"); 
                break; 

     } 

    } 

¿Podría ser simplemente un error nativo de Android?

Edit: Estoy usando esto para this.detector.onTouchEvent (me); para escuchar eventos de deslizamiento.

public class SimpleGestureFilter extends SimpleOnGestureListener{ 

    public final static int SWIPE_UP = 1;

     arg0.setAction(ACTION_FAKE);  //action which will be converted to an ACTION_UP later.          
     this.context.dispatchTouchEvent(arg0); 
     } 

     return false; 
    } 


     static interface SimpleGestureListener{ 
     void onSwipe(int direction); 
     void onDoubleTap(); 
    } 

    }

También recibí este error del mercado android.

parece como una cosa plataforma o un error que gotea abajo de algunos padres: http://code.google.com/p/android/issues/detail?id=10238#c6
