Question

You are building a PCF field component for a model-driven app that lets field technicians capture a photo of completed work directly from their mobile device camera. In your component code you plan to call context.device.captureImage(). During testing on a desktop browser and mobile, the method throws or is unavailable. What must you do to correctly enable this capability?

Accepted Answer

Declare the Device feature-usage element in the ControlManifest.Input.xml and call context.device.captureImage(), understanding it resolves at runtime based on the host's capabilities

Answer

Add the WebAPI feature in the manifest and use context.webAPI to upload the image, since camera access is only exposed through the Web API feature

Answer

Request the camera permission in a security role and no manifest change is required because device APIs are always available in the platform library

Answer

Set the of-type attribute of the property to Image in the manifest, which automatically wires the camera without any code
