OK, I understand now "that blank screen" is the delay in between while the activity is restarting.

How long does it take will strongly depend on what you're doing during onCreate(), since it is called every time the activity starts. You asked in the comments if threads will solve it: short answer, no, it's not that simple as spawning a new thread.

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
