public abstract List<CameraInfo> filter (List<CameraInfo> cameraInfos)
Filters a list of CameraInfos and returns those matching the requirements.
If the output list contains CameraInfos not in the input list, when used by a
CameraSelector then it will result in an
IllegalArgumentException thrown when calling bindToLifecycle.
The CameraInfo that has lower index in the list has higher priority. When used by
CameraSelector.Builder.addCameraFilter(CameraFilter), the
available cameras will be filtered by all CameraFilters by the order they were
added. The first camera in the result will be selected if there are multiple cameras left.
| Parameters | |

cameraInfos |
List: An unmodifiable list of CameraInfos being filtered. |
| Returns | |
|---|---|
List<CameraInfo> |
The output list of CameraInfos that match the requirements. Users are
expected to create a new list to return with.
