Android openCV is not streaming from the camera why?

Question

Android

I connected the library to the project normally (via Import module and setting build.gradle and dependencies). I registered the privileges for the camera in the manifest. Everything compiles and runs smoothly. The OpenCV Meneger application is present on the device. Applications on OpenCV from the market work.
Code taken from here . Swears at openCvCameraView.enableView():

Checked all this business on several phones and emulators.
What confuses me is that OpenCVLoader.initDebug() returns False.

Answer 1

I don't know what was the problem, but here is the working code .

Answer 2

>Methods onPause(), onResume(), onDestroy() removed, because their presence causes an error, which for some reason I could not trace.
So that's where the initialization is. Read errors in logs and fix them.
