Add set/get methods to set how the Visualizer scales the captured

3540a0197f56c4bcd7d7419f4502bfca34257de2 11-Jan-2012 John Grossman <johngro@google.com> Enhance Visualizer behavior in the case of mediaserver death.

Bring the Visualizer class into line with the SDK documentation by
the Visualizer loses its binder connection to the mediaserver because
of a mediaserver restart.

Also add a new callback interface to allow clients to be
asynchronously notified in the case of server death. Right now, the
interface definition and the registration method are flagged as hidden
pending API council review/approval.

See http://b/issue?id=5717519 for details.

Don't re-allocate buffers used by Visualizer callbacks as this causes an
unacceptable amount of GC thrash. Instead, lazily allocate the buffers and only
reallocate them when the required size changes.

See http://b/issue?id=5717519 for details.

2fb43ef8c0b922c1bd0d7cb6867e30d702d4bdb8 24-Sep-2010 Eric Laurent <elaurent@google.com> fix problem in AudioEffect JNI setup.

There is a problem in AudioEffect and Visualizer native_setup() methods
that causes a crash in the application after the mediaserver process
has crashed and restarted.
The problem is that the native AudioEffect/Visualizer constructor is
called while the JNI is in critical state after calling
GetPrimitiveArrayCritical(). As the mediaserver process just restarted, the
first call to AudioSystem will cause the binder IAudioflinger interface to
be reteived and a callback send to AudioSystem JNI to clear the mediaserver
error state. This will call env->FindClass() and crash due to the JNI being
in critical state.

Also fixed a similar problem in AudioTrack JNI

- Created sub-package android.media.audiofx for audio effects.
- Hid AudioEffect class contructor, methods and variables not needed by
- Added more javadoc comments for AudioEffect Class

df9b81ced437b11f8a3fcf4ba3ea6af703d121e2 02-Jul-2010 Eric Laurent <elaurent@google.com> Added Visualizer effect.

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).

Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.

This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc
