| /** |
| * <p> |
| * This class is a content provider that publishes the system settings. |
| * It can be accessed via the content provider APIs or via custom call |
| * commands. The latter is a bit faster and is the preferred way to access |
| * the platform settings. |
| * </p> |
| * <p> |
| * There are three settings types, global (with signature level protection |
| * and shared across users), secure (with signature permission level |
| * protection and per user), and system (with dangerous permission level |
| * protection and per user). Global settings are stored under the device owner. |
| * Each of these settings is represented by a {@link |
| * com.android.providers.settings.SettingsState} object mapped to an integer |
| * key derived from the setting type in the most significant bits and user |
| * id in the least significant bits. Settings are synchronously loaded on |
| * instantiation of a SettingsState and asynchronously persisted on mutation. |
| * Settings are stored in the user specific system directory. |
| * </p> |
| * <p> |
| * Apps targeting APIs Lollipop MR1 and lower can add custom settings entries |
| * and get a warning. Targeting higher API version prohibits this as the |
| * system settings are not a place for apps to save their state. When a package |
| * is removed the settings it added are deleted. Apps cannot delete system |
| * settings added by the platform. System settings values are validated to |
| * ensure the clients do not put bad values. Global and secure settings are |
| * changed only by trusted parties, therefore no validation is performed. Also |
| * there is a limit on the amount of app specific settings that can be added |
| * to prevent unlimited growth of the system process memory footprint. |
| * </p> |
