Android fragments and fragmentation

Android 3.0 introduces "fragments" for tablets, which act like activities but you can have several of them on screen at once.

However, since using fragments requires an Android 3.0 device, even if it's not a tablet, they've introduced some fragmentation, which is everyone's favourite reason to dislike Android.

So, to solve this problem, Google has released a fragments library for older API versions.

Effectively, what they've done is introduce a fragmentation library to deal with fragmentation introduced by introducing fragmentation.
