Regardless of which way you choose to go, configChanges or not, you'll want to cache any response you receive via HTTP. There are a lot of ways to cache these items. You could use static variables, save them temporarily to files on the internal or external (SD Card), add them to a database, etc.. Just remember to use disk storage if you need/want longer term cache copies as static variables are volatile.
When the view changes, just pull from the cached copies for the new layout. This could also be valuable for having something to display when a users runs your app again. You can keep the cached copy to display to them while you check for updated resources, then just replace anything that has been updated. This will make sure your users won't just be looking at a blank screen while you retrieve whatever info you need. Caching information is your friend and coming up with a good cache/update scheme that works for your environment will give your users a better overall experience.
