Why using Fragments?

Question

I have read the documentation and some other questions\' threads about this topic and I don\'t really feel convinced; I don\'t see clearly the limits of use of this tech

Answer 1

You shouldn't always use fragments. Fragments have their uses, such as when you want to page in and out parts of the screen or when you want to drastically change the UI in different orientations. When they make sense, use them. When they don't, skip them. I find they make sense in maybe about 10-20% of apps- I rarely see the need.
