Remarks
Allows clients to query availability and supported resolutions of camera extensions.
Camera extensions give camera clients access to device-specific algorithms and sequences that can improve the overall image quality of snapshots in various cases such as low light, selfies, portraits, and scenes that can benefit from enhanced dynamic range. Often such sophisticated processing sequences will rely on multiple camera frames as input and will produce a single output.
Camera extensions are not guaranteed to be present on all devices so camera clients must query for their availability via CameraExtensionCharacteristics#getSupportedExtensions().
In order to use any available camera extension, camera clients must create a corresponding CameraExtensionSession via CameraDevice#createExtensionSession(ExtensionSessionConfiguration)
Camera clients must be aware that device-specific camera extensions may support only a subset of the available camera resolutions and must first query CameraExtensionCharacteristics#getExtensionSupportedSizes(int, int) for supported single high-quality request output sizes and CameraExtensionCharacteristics#getExtensionSupportedSizes(int, Class) for supported repeating request output sizes.
The extension characteristics for a given device are expected to remain static under normal operating conditions.
