The Android Team always chooses flexibility over simplicity. It means that almost everything is doable with the framework but at the cost of ease of learning.

The Android Team always chooses flexibility over simplicity. It means that almost everything is doable with the framework but at the cost of ease of learning. I agree with Square on most of Fragment issues but I strongly disagree on their conclusions. 1- Fragment is hard to use at first, but it is not very manageable and not a source of hard to diagnose bugs if you use them well. 2- I don't see how introducing yet another framework to do the same thing but with less documentation and support is going to make things better.
