Q:

takePicture callback data is null

Is the Camera.takePicture callback for raw data null when running in emulator environment?
I got the CameraSurface method out of the WWW, so it should be correct.

A:

Before calling takePicture you have to provide a buffer large enough to hold the raw image data. (detailed here). For setting the buffer, use the addCallbackBuffer method.

A:

This issue seems to be related to the raw-data callback only.
Using the picture callback which retrieves a jpeg solves the issue.
