this my code for drag up current screen.
int screenWidth = getActivity().getWindowManager().getDefaultDisplay().getWidth();
int screenHeight = getActivity().getWindowManager().getDefaultDisplay().getHeight();
int fromX, toX, fromY, toY = 0;
fromX = screenWidth/2;
toX = screenWidth/2;
fromY = (screenHeight/2) + (screenHeight/3);
toY = (screenHeight/2) - (screenHeight/3);
int scroll_time = 10000;             
solo.sleep(5000);
    // Drag UP  
solo.drag(fromX, toX, fromY, toY, 40);
Log.d(TAG, "Drag 1");
    // here default origin (x,y = 0,0) is left upper corner
here scroll is working but very slow.
So for fast scroll what changes in this code required ?
