| 32 | * This class provides access to the system uimode services. These services |
| 33 | * allow applications to control UI modes of the device. |
| 34 | * It provides functionality to disable the car mode and it gives access to the |
| 35 | * night mode settings. |

| 37 | * <p>These facilities are built on top of the underlying |
| 38 | * {@link android.content.Intent#ACTION_DOCK_EVENT} broadcasts that are sent when the user |
| 39 | * physical places the device into and out of a dock. When that happens, |
| 40 | * the UiModeManager switches the system {@link android.content.res.Configuration} |
| 41 | * to the appropriate UI mode, sends broadcasts about the mode switch, and |
| 42 | * starts the corresponding mode activity if appropriate. See the |
| 43 | * broadcasts {@link #ACTION_ENTER_CAR_MODE} and |
| 44 | * {@link #ACTION_ENTER_DESK_MODE} for more information. |
| 45 | * |
| 46 | * <p>In addition, the user may manually switch the system to car mode without |
| 47 | * physically being in a dock. While in car mode -- whether by manual action |
| 48 | * from the user or being physically placed in a dock -- a notification is |
| 49 | * displayed allowing the user to exit dock mode. Thus the dock mode |
| 50 | * represented here may be different than the current state of the underlying |
| 51 | * dock event broadcast. |
