Save and restore instance state: Java Design Patterns and APIs for Android
Save and restore instance state: Java Design Patterns and APIs for Android

Most of the techniques for managing data in memory in Java don’t change in Android. You’re using basic Java architectures. When you want to work with a value only within a method, define a variable that’s local to that method. To persist a value for the lifetime of an Activity, declare it as an instance field of the Activity class. To make values available to the rest of the application, set a field’s access identifier to public. These basic patterns are common to all Java applications, regardless of platform or application framework.
