Hello Sir, Thank you for the tutorial it worked great for me. For anyone it interests I have used OpenCV 3.4.10 with the latest version of Android Studio and it worked for me so you can use this version too to follow the tutorial.

If you're getting a black screen rather than video, you probably need to change the version you're using to match what is used in the video.  In my case, I was able to use 3.4.5.  I was using 4.5.3, which just gave the black screen.
