What is the best way to go about designing an Android application that features quite a bit of formulas and conversions? I was thinking that multiple Activities with ListViews sort of like a tree with the leaves being the actual calculations. However, after reading Android design principles it's better to avoid a pure navigational structure and try to reduce the deepness of the app.
Main Menu Conversions Weight Distance Distance - Speed - Time Calculate air speed Calculate distance traveled Weather METAR TAF
So by the 3rd or 4th screen we've reached the actual individual calculator. Does this make sense? And if it does, is there a better way of designing this (maybe using action bars or tabs)?
However, on StackOverflow it was mentioned using ExpandableListView. I'm necessarily sure this would be the best way.
