Well something isn't working correctly and I don't think it's aapt, unless aapt is somehow causing the PNG to lose some information that the decoder uses. I'm using PNGs encoded by photoshop with obvious transparency (some with 100% in areas, others with partially transparent pixels) and many of them are decoded with a null bitmap configuration or as RGB_565.
I've been having this problem for a year but I have just been using workarounds. It was just today that it got on my nerves :) On May 14, 5:42 pm, Romain Guy <[email protected]> wrote: > aapt will optimize PNGs already, no need to do it in Photoshop.
