I haven’t seen this mentioned anywhere. Usually Android app icons feature a transparent background, unlike the squared status quo of the iOS family.
However, the Samsung Galaxy S’s launcher sets different icon backdrops for my various apps. On my own app, he attributed a green sunshine, and I see that pattern on some other apps I have installed. The default apps also have various backdrops.
Can I specify what backdrop to show for my app?
Galaxy S (as other models by same manufacturer) uses a different launcher.
This is not the default one released with Android AOSP featuring transparent icon background.
This launcher automatically (part of TouchWiz UI) adds a square background to every icon.
There’s no way you can do the same without changing it on your phone.
