ThreadPool with Camera Preview

Download the demo app on Google Play.

This project demonstrate how to use HandlerThreads and ThreadPools to burst capture images from Android's Camera API on a background thread. The images are then:

• 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.

The CameraPreview YUV byte[] is captured on a background HandlerThread and then ThreadPools are used to perform the operations above to improve speed and performance.
