This sits on top of the * asset manager of the application (accessible through {@link #getAssets}) and * provides a high-level API for getting typed data from the assets. * *

The Android resource system keeps track of all non-code assets associated with an * application. You can use this class to access your application's resources. You can generally * acquire the {@link android.content.res.Resources} instance associated with your application * with {@link android.content.Context#getResources getResources()}.

* *

The Android SDK tools compile your application's resources into the application binary * at build time. To use a resource, you must install it correctly in the source tree (inside * your project's {@code res/} directory) and build your application. As part of the build * process, the SDK tools generate symbols for each resource, which you can use in your application * code to access the resources.

* *

Using application resources makes it easy to update various characteristics of your * application without modifying code, and—by providing sets of alternative * resources—enables you to optimize your application for a variety of device configurations * (such as for different languages and screen sizes). This is an important aspect of developing * Android applications that are compatible on different types of devices.

* *

For more information about using resources, see the documentation about Application Resources.
