Android application launcher icon has a black background

I saved an image in photoshop using save for web, 24 bit png, with transparency checked.

I then generated my icons using the Android Asset Studio.

My launcher icon has a black background on my device (Captivate), but does look fine on my emulator.

Any advice on how to get the icon to not have the black background on my device?

Tha开发者_如何学Pythonnks in advance!

Save it as a 32 bit png, that way you get the full 8-bit transparency.

Samsung TouchWiz is what's putting the icon backdrops on.
