IllegalArgumentException

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.
