Hi John, The destinations are drawn from an array.
This means each line gets drawn separately. Therefore when removing the loaders you need to make sure you backtrack all the lines and not just the last one. This applies for everything built by retrieving objects. A very common error by coders. Just remember that every xml line is like one element in an array. If you test this with images, you will find eventually you overload the memory as objects are just being stacked one on another. Very difficult to pick up when you are are not experienced with the construction and deconstruction methods of a language.. After practicing with the different listeners and watching your mobile device slow to a grinding halt you will learn to find these issues. Read up about how you should be using removeListener.
