| /** |
| * Notifications for iorapd specifying when a system-wide intent defaults change.<br /><br /> |
| * |
| * Intent defaults provide a mechanism for an app to register itself as an automatic handler. |
| * For example the camera app might be registered as the default handler for |
| * {@link android.provider.MediaStore#INTENT_ACTION_STILL_IMAGE_CAMERA} intent. Subsequently, |
| * if an arbitrary other app requests for a still image camera photo to be taken, the system |
| * will launch the respective default camera app to be launched to handle that request.<br /><br /> |
| * |
| * In some cases iorapd might need to know default intents, e.g. for boot-time pinning of |
| * applications that resolve from the default intent. If the application would now be resolved |
| * differently, iorapd would unpin the old application and pin the new application.<br /><br /> |
