Error
Its pointing to
holder.placeTitle.setText(mPlaces.get(position).getPlaceName());
If you debug, you'll see that mPlaces.getSize() equals 1, and trying to access the item in position 1, you'll get an ArrayOutOfBounds exception.
there is something wrong in your ArrayList and it probably doesn't have all the data you are trying to get.
