Using Camera API

Android SDK supports the connectivity to the built-in camera. Using the camera to take photos is relatively easy. It is somewhat harder to setup the camera preview to work properly.

In our main activity, we create the Preview object. This object will create the Camera object and return it to the CameraDemo activity.


Next we register couple of call-back method with the Camera to be performed when the user takes a photo.

shutterCallback is called when the shutter is opened and picture is taken. rawCallback and jpegCallback will get the data for the raw and jpeg encoding of the photo. It's up to you to do something with this data, such as save it to the SD card.
