Hi Team,
We build a app with ar and QR code scanner feature, we found a issue that ar will not working after open scanner then close it,
and open ar, the ar screen become black that cannot open camera.
The Log:

If I have to guess, I'd suspect that your your QR scanner code is not releasing the camera fully. Have you done a thorough search for the errors in the log? I've found plenty of hits for it.
Hello,
Hello,
Agree with @dpizzle. This is because another process has the camera thread.

Hi Team,
Hi Team,
The logs of operation:
1.QR (ok)-> AR (ok) -> QR (ok) ->AR (fail, black screen),kill app,AR(ok)
2.AR (ok) ->QR(ok) -> AR(fail) ->QR(ok), kill app, AR(ok)
We found AR cannot be released when close it then click QR manually.
Hello,
Hello,
I can think of two ways:

how did you solve that issue?
Could you share the solution?
