Android devices provide application services to operate the camera and either save or return a bitmap.
Chester Wilson at ADUG provides a simple application demonstrating
•a form to adjust the Camera options.
•the use of a Media Action Item to access the Android's inbuilt camera service and
•using a multi-platform Camera component to "Preview" the camera image and then "save" a snapshot.
Permission to use the camera and any file access has to be enabled obviously but to use the inbuilt camera service I needed to also add Entitlements>Secure Files to the application options so a "file provider" was included in the manifest even if the service was not being used to save files.
