About the Book
You have a good start on building your Android application, but now comes the time to store the data entered by your users on their device. It's an important part of any application; even a quick prototype needs a way to store data. What is the best way to do it?
Here is a quick guide to get you started with the tools available in the Android SDK, without having to learn yet another new framework or library. You'll learn how to :
- Save simple data to flat files in the internal and external storage of the device,
- Save user preferences using the Preferences API,
- Save structured data in an SQLite database,
- Save images so you can refer to them in a SQLite database,
- Persist the state of an activity so users don't lose their input just because they rotated their device or took a phone call.
This guide also includes examples to help you implement all of those in your own Android applications. Purchase now and you can be up and running in a few minutes!
