The Android team sure has a sense of humor. Previously, in the Froyo SDK, besides tons of awesome code, they've also added a function called wtf() (What a Terrible Failure) and an even more hilarious isUserAMonkey() that returns true if the user interface is currently being messed with by a monkey.
Examining the Honeycomb SDK docs released earlier today, armed with a hint from Roman Nurik, I found the following gem: fyiWillBeAdvancedByHostKThx(). The docs are not online yet, but if you've downloaded the SDK, you can find this function at android-sdk/docs/reference/android/widget/
AdapterViewAnimator.html#fyiWillBeAdvancedByHostKThx(). What it does doesn't matter (it's actually a legitimate function), but its name is hilarious.
Next up we have what seems to be a Tron-themed Honeycomb logo, buried within the depths of the SDK drawables:
The logo shows itself show up in an even more Tron-themed Easter egg found in the same location as the one present in Gingerbread. Like before, to activate it, go to Settings > About and tap Android version repeatedly:
That's it for now - I haven't found other interesting bits or Easter eggs just yet. If you find any, please post them in the comments below.
