[android-developers] Re: Activity/Intents inTabs

[cwgrc2]

Hi Mark.  I have bought your book and re-read the "Put it on my Tab"
section several times.  I have two activities because your book
recommends using different ones to cature different grouping of
Widgets.  So my main Actvity has one page (tab) of Widgets that
collect the information and start a stopwatch, then that information
feeds into a MapActivty that is on a different tab.  Again, each tab
has many different things on them and I want to be able to freely
communicate between them.

Thanks,

Chris

I sure hope not. I'll need to fix that section.

I have found zero good reasons for using activities in tabs. Having
multiple activities as first-class UI components is great -- but for
tabs, I recommend just using Views.

Which is precisely why you do *not* want those in separate Activities.
