Hello. When i open activity.xml file and preview it, error occured

Rendering Problems The following classes could not be instantiated:
- net.jonreynolds.androidopencvcamera.MyGLSurfaceView (Open Class, Show Exception, Clear Cache)
 Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the
 IDE.  
If this is an unexpected error you can also try to build the project, then manually refresh the layout.  
Exception Details
 java.lang.ClassNotFoundException: org.opencv.android.CameraGLSurfaceView$CameraTextureListener

I cleaned project and deleted cache but it is not working
How to fix it. Thanks

I already followed the instruction but Android Studio does not show the play or run button as follows.

I used Windows 10, Android Studio, and OpenCV Android SDK with the latest version.

Hi, thanks for your sharing. This is a great project. However, when I was using it, I found several places that can make it even better. Firstly, I think you can include the opencv module in this repo, so that people don't need to download it and link it again. Secondly, in CMakeList.txt, the project path and opencv path is absolute paths (/Users/jonathanreynolds/Documents/Projects/OpenCV-android-sdk). For newbies, this may be confusing. Thirdly, the libopencvjava3.so can also be included in the repo. Therefore, newbies won't need any extra effort to load it on a phone immediately.

Thanks for your sharing again!
