startPreloading() is not relevant to this; that is for the code there that is preloading the drawables it gets from the array.
Is there actually a sym_def_app_icon drawable in your app? If not... well yeah, that won't work, it doesn't exist. You should just use the syntax I showed to make an array of references to your *own* drawables, which you can retrieve with the same code as shown using obtainedTypeArray(). The last XML syntax you have shown is just not right, so it's not surprising it doesn't work. On Fri, Dec 17, 2010 at 8:42 PM, darrinps <darri...@gmail.com> wrote: > Thanks.
