Parameters

request

CameraCaptureSession.CaptureCallback

The callback object to notify every time the request finishes processing. If null, no metadata will be produced for this stream of requests, although image data will still be produced.

handler

Returns

int A unique capture sequence ID used by CaptureCallback#onCaptureSequenceCompleted.

Attributes

Exceptions

if the camera device is no longer connected or has encountered a fatal error

if this session is no longer active, either because the session was explicitly closed, a new session has been created or the camera device has been closed.

If the request references no Surfaces or references Surfaces that are not currently configured as outputs; or the request is a reprocess capture request; or the capture targets a Surface in the middle of being Prepare(Surface); or the handler is null, the listener is not null, and the calling thread has no looper; or no requests were passed in.
