Demo of burst capturing images with camera API using CameraPreview.
The app captures the Camera Preview on a background handler thread.
It then performs the following actions in a threadpool.
* Converted from YUV `byte[]` to RGB `int[]`.
* Converted from RGB `int[]` to `Bitmap`.
* Bitmap is rotated if needed to fix orientation.
* A Thumbnail size Bitmap is made for displaying.
* Full size bitmap is written to disk as a Jpeg.
* JPEG image is uploaded to a server (mock upload, does not really upload anything).
