The available stream configurations that this camera device supports; also includes the minimum frame durations and the stall durations for each format/size combination.
All camera devices will support sensor maximum resolution (defined by CameraCharacteristics#SENSOR_INFO_ACTIVE_ARRAY_SIZE android.sensor.info.activeArraySize ) for the JPEG format.
For a given use case, the actual maximum supported resolution may be lower than what is listed here, depending on the destination Surface for the image data.
