If you are a WPDev and building Windows Phone app and/or game that uses primary or secondary (front facing camera), you might need to check whether the device supports either or both of them. Windows Phone SDK provides APIs to check for supported camera type.
In this blog post, we will discuss about this API and learn how to know whether the phone supports either or both of those camera types.
The abstract class “Camera” present under the namespace “Microsoft.Devices” provides you the required API to check whether the Windows Phone device supports Primary Camera or Front Facing Camera. The Camera class contains a static method named “IsCameraTypeSupported(CameraType type)” that returns a boolean value indicating whether the passed CameraType is available in the device. The parameter of CameraType could be either “Primary” or “FrontFacing”.
Here is the code to know the supported camera type in a Windows Phone device:
// this will return boolean value indicating whether the device has Primary Camera var hasPrimaryCamera = Camera.IsCameraTypeSupported(CameraType.Primary);
// this will return boolean value indicating whether the device has Front Facing Camera var hasFrontFacingCamera = Camera.IsCameraTypeSupported(CameraType.FrontFacing);
While using the camera APIs in Windows Phone, you might get an “UnauthorizedAccessException” as shown below, if you did not configure your project to apply proper capability settings:
To do this, open the WMAppManifest.xml file and navigate to the Capabilities tab as shown in the below screenshot. There you will find a checkbox named “ID_CAP_ISV_CAMERA” listed under the Capabilities. Mark this capability as checked and you will be good to go.
