title: Camera permission is not working
body: <p>I am using OpenCV4Android version 3.0.0. I am trying to access the camera through OpenCV lib, actually I managed to open it.But the problem i am currently facing is, when i create a new project and importe OpenCV lib I can not use the camera and I receive the following message when i run the App
  despite the permissions are added to the manifest file as shown below</p>
