Java Development

The solution is in two parts.

First, you will have to invoke tha camera app by calling net.rim.blackberry.api.invoke.Invoke.invokeApplication(int appType, ApplicationArguments args).

Next, you need to implement a net.rim.device.api.io.file.FileSystemJournalListener to listen for changes in the file system. A change in the file system may represent that a picture has been taken using the camera application and is saved. Once this event is triggered, you can use net.rim.device.api.io.file.FileSystemJournal to get the path of the image file and you are good to go from here.

You can reference the fileexplorer demo that is included with the BlackBerry JDE for an example of this.

In 4.6, the camera itself can be embedded within your application.  Check out VideoControl.getSnapshot().  The camerademo in the samples directory of JDE 4.6 demonstrates how to use this API.

I thought the VideoControl was just for playing video. I couldn't figure out how to view live video from the camera? Are you sure it's for live video FROM the camera? If so can you paste the specific code?

Thanks

The preview window is live from the built in camera.  Please have a look at the camerademo included with the version 4.6 BlackBerry JDE for an example.
