Answer 1

You may want to consider using onRetainNonConfigurationInstance() for the heavy objects in your activity. Take a look at this article for a excellent explanation: http://developer.android.com/resources/articles/faster-screen-orientation-change.html .

Alternatively, you can use static data in an Application class. See the Application as a Singleton post here: http://androidcookbook.com/Recipe.seam?recipeId=1218

Answer 2

You need to use responsive design for your pages. There are a few templates available such as Skeleton and Initializr. If you don't want to use the templates you can just add CSS3 media queries yourself to set different div sizes based on screen width.
