Answer 1

高质量保存png（24）

Answer 2

Not sure if this is the same issue, but I was getting a blurry png image too which I reference from an ImageView in my layout xml file. It is a 24 bit image also, but it wasn't until I saved the image with a larger width and height that it actually looked good. I went from a width of 88 to 250 and now the image looks great.
