Each time you remove an item from the array at the lower lever, the total count is being reduced by 1. If you had 4 items to remove [ 0, 1, 2, 3], and you remove items starting with item 0, you have [0, 1, 2], then you remove item at 1, and you have [0, 1], if you try to remove item at index 2 which does not exist you will get an error. Try count down instead of up like this

for(int i = size; i > 0; --i)
{
  if(checkedPositions.valueAt(i))
  {
    list.remove(checkedPositions.keyAt(i));
    notes.notifyDataSetChanged();
    lv.setItemChecked(i,false);
  }
}
