Working with Files

  • Grant Allen


Android offers quite a wide range of approaches to the topic of dealing with storing, and retrieving, data for you applications. In the next three chapters, I cover the major features that allow you to store data away, to process it, to use it for logic and other functions in your application. Android offers a built-in preference system for maintaining state about a user’s settings, options, and preferences. Bundled with all Android installations is a fully working SQLite library, which provides embedded relational database capability. The last main data storage technology Android supports is the traditional file, stored on a file system.
