If you have data in memory that needs to stick around during an orientation change, you need to do something to arrange that. The best solution is to implement onSaveInstanceState() and use it to store your data, because that gets used not only for orientation changes, but other situations as well (e.g., your activity is on the current stack, but it needs to get kicked out of RAM to free up space for things later in the stack).
