how did you do the pre-dithering? our designer created a host of images with dithering enabled, but it didn't have any effect. The artifacts would only disappear when setting setDither(true) on EVERY SINGLE drawable having a gradient. This seems like a major framework fail... 16Bit graphics? It's

Except that phone displays do not display more than 16 bits of colors. The displays are natively 565. Are you sure that applies to the Samsung Galaxy, the phone that the first post in this thread mentioned things are looking bad on? The first spec sheet I could find for it says 16M Color AMOLED

To do a true comparison of what the PNG is like after 'optimization' take it out of the final APK, it is just a zip archive. The banding artifacts you see are because the device and the emulator are displaying in 16-bit 565 pixel format, they can't display all the colors. Have you tried painting

Thanks. I've checked it and the optimization do not affect the colors the way that is shown on the emulator/device. I've tried to define a proxy XML for the PNG and set its dither to true, but it didn't worked. I'll try to change the png image settings on photoshop or something. I've found some
