Work with files in internal storage

Work with files in internal storage: Android Development Essential Training: Local Data Storage
Work with files in internal storage: Android Development Essential Training: Local Data Storage

You can store information persistently on an Android device in simple files, either text-based or binary. For the examples in this chapter, I’ll focus on simple text, since it’ll be easier to see the results, but binary files work pretty much the same way as in any other Java-based platform. Android distinguishes between internal and external storage areas. Files saved to internal storage are hidden from the device user, and are tightly associated with the app. When an app is uninstalled, any files in its internal storage area are deleted automatically. Many files that are created by parts of the Android SDK, such as SQLite databases and shared preference files, are always created in this internal storage area, but you can create your own arbitrary files there as well.
