The only modern technology that can compete with mobile phones for ubiquity is the portable digital media player. As a result, the multimedia capabilities of mobile devices are a significant consideration for many consumers.
Android's open platform and provider-agnostic philosophy ensures that it offers a multimedia API capable of playing and recording a wide range of image, audio, and video formats, both locally and streamed.
The Camera API and OpenCORE multimedia platform expose these capabilities to your applications, providing comprehensive multimedia functionality.
In this chapter you'll learn how to play and record multimedia content including audio, video, and still images, as well as use the camera to capture images and preview and record live video.
You'll also learn how to manipulate raw audio files using the Audio Track and Audio Record classes, add newly recorded media files to the Media Store, and make use of speech recognition to add voice input to your applications.
