The Media APIs are used to play and, in some cases, record media files. This includes audio (e.g., play MP3s or other music files, ringtones, game sound effects, or DTMF tones) and video (e.g., play a video streamed over the web or from local storage).
Other special classes in the package offer the ability to detect the faces of people
in Bitmaps (FaceDetector), control audio routing (to the device or a headset)
and control alerts such as ringtones and phone vibrations (AudioManager).
