I would like to notify the user that the camera is unavailable until they turn on the camera permission.  However, the only permissions I can find in the API is under BBM, and isn't related.

How do I find this out?

Have you tried checking the allCamerasAccessible flag: https://developer.blackberry.com/cascades/reference/bb__cascades__multimedia__camera.html#allcameras...

allCamerasAccessible may not do exactly what you want.

It may tell you that cameras are inaccessible because they are already in use by another app.

I think you ultimately want to call into authman some how to determine if you have the permission or not.

I'll have to check on this.

camera_get_supported_cameras() is one native API you could try using.

http://developer.blackberry.com/native/documentation/bb10/com.qnx.doc.camera.lib_ref/topic/camera_ge...

This function calls eaccess() to determine if your app has access to the camera devices.

If you invoke it as:

unsigned int num=0;
camera_get_supported_cameras(0, &num, NULL);

Then num should contain the # of camera devices accessible.  If this # is 0, then it's safe to assume your app doesn't have permission.  Either that or you are running on a device which has no cameras
