The Android `Camera` module can record over 160 parameters per frame. To retrieve a specific key value, use `getImageMetadata()`, handling `MetadataNotFoundException`. The example demonstrates fetching the `SENSOR_EXPOSURE_TIME` metadata, using `getLong()` method and handling `NotYetAvailableException` if sensor data is unavailable. Refer to the `ImageMetadata` documentation for the complete list of available keys.\n"]]
