| 47 | * Class for accessing an application's resources. This sits on top of the |
Scott Main | f4f05b8 | 2011-01-07 14:38:23 -0800 | [diff] [blame] | 48 | * asset manager of the application (accessible through {@link #getAssets}) and |
| 49 | * provides a high-level API for getting typed data from the assets. |
| 50 | * |
| 51 | * <p>The Android resource system keeps track of all non-code assets associated with an |
| 52 | * application. You can use this class to access your application's resources. You can generally |
| 53 | * acquire the {@link android.content.res.Resources} instance associated with your application |
| 54 | * with {@link android.content.Context#getResources getResources()}.</p> |
| 55 | * |
| 56 | * <p>The Android SDK tools compile your application's resources into the application binary |
| 57 | * at build time. To use a resource, you must install it correctly in the source tree (inside |
| 58 | * your project's {@code res/} directory) and build your application. As part of the build |
| 59 | * process, the SDK tools generate symbols for each resource, which you can use in your application |
| 60 | * code to access the resources.</p> |
| 61 | * |
| 62 | * <p>Using application resources makes it easy to update various characteristics of your |
| 63 | * application without modifying code, and—by providing sets of alternative |
| 64 | * resources—enables you to optimize your application for a variety of device configurations |
| 65 | * (such as for different languages and screen sizes). This is an important aspect of developing |
| 66 | * Android applications that are compatible on different types of devices.</p> |
| 67 | * |
| 68 | * <p>For more information about using resources, see the documentation about <a |
| 69 | * href="{@docRoot}guide/topics/resources/index.html">Application Resources</a>.</p> |
