Daniel Sandler | 2d78490 | 2012-10-03 23:04:50 -0400 | [diff] [blame] | 46 | * Extend this class to implement a custom Dream (displayed to the user as a "Sleep Mode"). |
Dianne Hackborn | be87e2f | 2012-09-28 16:31:34 -0700 | [diff] [blame] | 47 | * |
| 48 | * <p>Dreams are interactive screensavers launched when a charging device is idle, or docked in a |
| 49 | * desk dock. Dreams provide another modality for apps to express themselves, tailored for |
| 50 | * an exhibition/lean-back experience.</p> |
| 51 | * |
Daniel Sandler | 2d78490 | 2012-10-03 23:04:50 -0400 | [diff] [blame] | 52 | * <p>The Dream lifecycle is as follows:</p> |
| 53 | * <ul> |
| 54 | * <li>onAttachedToWindow</li> |
| 55 | * <li>onDreamingStarted</li> |
| 56 | * <li>onDreamingStopped</li> |
| 57 | * <li>onDetachedFromWindow</li> |
| 58 | * </ul> |
| 59 | * |
| 60 | * <p>In addition, onCreate and onDestroy (from the Service interface) will also be called, but |
| 61 | * initialization and teardown should be done by overriding the hooks above.</p> |
| 62 | * |
| 63 | * <p>To be available to the system, Dreams should be declared in the manifest as follows:</p> |
