| 67 | * Classes added here should be things that are expected to live the lifetime of sysui, |
| 68 | * and are generally applicable to many parts of sysui. They will be lazily |
| 69 | * initialized to ensure they aren't created on form factors that don't need them |
| 70 | * (e.g. HotspotController on TV). Despite being lazily initialized, it is expected |
| 71 | * that all dependencies will be gotten during sysui startup, and not during runtime |
| 72 | * to avoid jank. |

| 74 | * All classes used here are expected to manage their own lifecycle, meaning if |
| 75 | * they have no clients they should not have any registered resources like bound |
| 76 | * services, registered receivers, etc. |
