android - Multiple step registration process in a single activity with fragments -

-

i'am trying create multiple-step registration activity handles several fragments. each fragments step in process , final fragment should send registration information collected in fragments server , response. problem thinking how should handle information across fragments if user goes 1 step not loose typed information. , how should handle these fragment transactions. thinking in storing data in activity , retrieve each time user goes 1 step , retrieve in final fragment send information don't think best approach. there way cleanly?

since fragments run on top of activities, think way cleanly have fragments communicate activity.

basically approach thinking correct.
