Granted, it would be much better if Google created a full library-as-

instead of looking for them in the filesystem. But this should work
as long as nothing is meddled wit

Performance has more to do with your database schema than with the

You are not very specific about what you are doing, but in general the
"container" section of your layout -- the RelativeLayout part -- would
be set to "match_parent", but a typical widget such as a Button would
be set to "wrap_content" because you don't want it to be any larger
than it has to be.
To wrap this up, I've found that the arguments "sent" to the fragment
with setArguments are preserved when the fragment is reinstantiated by
the framework. So what I'm now doing is only creating a new fragment
if there is no previous one after a config-change restart. For
example:

then I'd need to use the manager findFragmentByTag call to find these
recreated fragments since I need to be able to add them to their
container view and also to be able to call custom methods that update
the displayed data, etc.
My app is built with V4 of the Compatibility Library (in case that makes
a difference) and all of my fragments are "dynamic". That is, I
explicitly create the fragment objects and put them in a view with an
"add" or similar transaction, etc.
What I have discovered is that, when my activity is
