__MultiMedia__
Important MultiMedia classes:
* AudioManager & SoundPool
* RingtoneManager & RingTone
* MediaPlayer & MediaRecorder
* Camera
__AudioManager__
* manages volume, system sound, effects and ringer mode control
* acquire AudioManager instance via Context.getSystemService(Context.AUDIO_SERVICE)
* then Load and Play sound Effects, manage the volume, manage Peripherals
__SoundPool__ represents a collection of audio, multiple sample at the same time
__RingToneManager__ provides access to audio clips used for incoming phone calls, notifications, alarms etc.
It allows application to get and set ringtones and to stop/play them.
__MediaPlayer__ controls the playback of audio and video streams and files.
common methods
* setDataSource() - which streams to play
* prepare() - initializes the player and loads the streams (it is synchronous, there is also an asynchronous version)
* start()
* pause()
* seekTo()
* stop()
* release()
__VideoView__ is a subclass of SurfaceView. Used for displaying video.
__MediaRecorder__ used to record audio and video (state machine). Use ''setAudioSource()'' , ''setVideoSource()'', and the other usual ones.
__Camera__ - access the camera service. Your application can capture images, start/stop preview. You need CAMERA permissions of course. Also specify the ''uses-feature'' tag in AndroidManifest.xml.
Commona approach:
* get camera instance
* set camera parameters
* setup and start the preview display (so the user can see what the camera sees)
* take a picture & process image data
* release the camera
