| * Class to handle ugly dependencies throughout sysui until we determine the |
| * long-term dependency injection solution. |
| * |
| * Classes added here should be things that are expected to live the lifetime of sysui, |
| * and are generally applicable to many parts of sysui. They will be lazily |
| * initialized to ensure they aren't created on form factors that don't need them |
| * (e.g. HotspotController on TV). Despite being lazily initialized, it is expected |
| * that all dependencies will be gotten during sysui startup, and not during runtime |
| * to avoid jank. |
| * |
| * All classes used here are expected to manage their own lifecycle, meaning if |
| * they have no clients they should not have any registered resources like bound |
| * services, registered receivers, etc. |
