Move drawables to "drawable-nodpi" instead of "drawable" to get correct bitmap sizes

Hi,
in demo your bitmaps in memory are astronomically huge as they are in "drawable" folder, which is "drawable-mdpi" and if you run it on modern xxxhdpi phone, you will get multiplier * 4 (i think) of each dimension, there fore each bitmap is 16times bigger in memory (124mb+ bitmaps)

Start in the demo's Android resources and locate the bitmaps currently stored in drawable. Move the affected assets to drawable-nodpi, then run the demo on a high-density device or emulator and verify that bitmap dimensions are not density-scaled and memory use is reduced.
