Currently VoiceDialer cannot show a candidate when it has a type
the recognition engine cannot recognize. For example if a
contact has one phone number with the type CUSTOM, VoiceDialer
never shows the person as a candidate even when a user ask so
("Call XXX").

This change prepares "fallback" phone number id and use it when
there's no other available ids with recognizable types, to support
the case above.

TESTED:
- Have a contact (say "Ada" here) with several phone numbers one
of which must have a custom type which isn't supported by
VoiceDialer ("CUSTOM"). Say "Call Ada" and see if that custom
phone number appears as another entry ("Call Ada")
- Try "Call Ada at home" or other voice command and see they work
as before.

Bug: 5234283
Apparently in Honeycomb, a change was made so that
an onscreen activity would be stopped when the screen
turned off. This was not the case in prior releases.
The VoiceDialerActivity was initializing the TTS
engine and recognizer engine in onStart(), and
tearing everything down in onStop(), which means
that post Honeycomb, it doesn't work if the screen is off.

Now, it initializes everything in onCreate() and
tears it down in onDestroy().

It would be much better if all of the connections to
the TTS engine and bluetooth, along with the state
control, were kept in a service. This way the activity
could be dumb, and it could be destroyed and recreated
without losing state. That's far too big of a change for
ICS at this point though.

fbc76d73e034753bf284d52f0df766369ae3cb5b 27-Apr-2010 Martin Hibdon <mah@android.com> Fix Bugs 2626599 and 2615852

Prior to this change, VoiceDialerActivity would decide
whether to run in bluetooth mode based upon the intent
that started it. If it was ACTION_VOICE_COMMAND, then
it would run in bluetooth mode.
There are two problems with this:
1. If there is a bluetooth headset connected, but
the voicedialer is launched from the menu, then
it will come up in non-bluetooth mode, so the audio
would not be routed correctly and it would not prompt
the user via TTS.
2. If there is not a bluetooth headset connected, but
and then something other than the headset fires the
ACTION_VOICE_COMMAND, it will come up in bluetooth mode,
and then block indefintely trying to connect to the
headset.

With this change, the VoiceDialerActivity always creates
a BluetoothHeadset object. It waits for the first onServiceConnected
callback to decide which mode to run in. Now it runs in the
correct mode, regardless of how it was launched.

These had been separated into two activites while the BluetoothVoiceDialer
was being worked on, but it's a lot of duplicate code. Now there is a single
activity that can run in either bluetooth or non-bluetooth mode, depending
on how it is started.
The state transitions are slightly simpler when running in non-bluetooth
mode, because it does not use text to speech to inform the user about
what it is doing.

ef5d3e8cd31873c7af4902986ae61b408d0343bb 20-Apr-2010 Martin Hibdon <mah@android.com> Fix Bug: 2606879

The problem is that if the user leaves the VoiceDialerActivity
using the home button, when it is started again it never starts
listening. This is because all of the initialization is done
in onCreate, but the teardown is done in onStop. When the
activity is left using the home button, the activity is stopped,
but not destroyed, so onCreate is never called when the activity
is started up again.

This change moves the initialization to onStart, and leaves teardown
in onStop. It really doesn't make any sense for this particular activity
to be stopped or paused, if it's stopped at all it should be finished.
So now the onStop function also calls finish().

When starting the voiceDialer, there is a tone played
to indicate that the microphone is listening. It's
important the tone not be picked up by the mic and
sent to the recognizer engine, or it will corrupt
the sample. Prior to this change, the VoiceDialerActivity
would simply pull a fixed 380 milliseconds of audio
from the microphone inputStream. This works, but
may not be reliable on all hardware platforms because
the size of audio buffers and performance of the audio
system may vary.
Now, the VoiceDialerActivity removes audio samples
and attempts to detect the tone. When the tone ends,
it stops pulling samples. If no tone is detected within
500 milliseconds, it times out and stops removing samples.

1b715dc663bd7155d996576774e487d31bf331f7 13-Apr-2010 Martin Hibdon <mah@android.com> Put the beep back into the voiceDialer

Bug: 2326485
Now the VoiceDialerActivity plays a beep just as it starts listening.
The hard part here is that we need the end of the beep to line up
pretty accurately with the start of the microphone listening.
If the beep happens before the microphone is listening, then the
user will start speaking too soon. If the beep happens after the
microphone is listening, then the sound corrupts the incoming sample.

The other difficulty is that the time to start the microphone varies
considerably from platform to platform, so there is no practical way
to time the beep so matches. So instead, the VoiceDialerActivity
will play the beep after the mic starts, and then pull the first part
of the audio sample off of the incoming stream.

The beep is 40 milliseconds long, but there is some lag in between
requesting the tone to play and getting it back on the mic.
Experimentally, pulling out the first 350 milliseconds of sample
removes the beep without losing too much else on both Passion
and Sholes.

Use stream STREAM_BLUETOOTH_SCO instead of STREAM_VOICE_CALL for TTS playback.
It is more appropriate as it corresponds to current user setting for the bluetooth
headset now that STREAM_BLUETOOTH_SCO and STREAM_VOICE_CALL are not synchronized
any more.
Also limit volume to an absolute max of -18dB instead of dividing it by 2 in order
to avoid saturation without impacting lower volumes.

Bug: 2537307
The recognizer has a limit on the size of each semantic value
in the grammar. Now that we are storing both the package name
and class name there, it's pretty easy to overflow that limit,
causing the grammar initialization to fail. With this change,
only the spoken word is stored in the grammar (i.e. "calendar").
The mapping of words to package name/class name is stored
explicitly in a hashTable inside the commandRecognizerClient,
which circumvents the recognizer's fixed limit.

Bug: 2497802
If the orientation changes while an alert dialog is up,
the dialog would leak and causes an assertion failure.
With this change the VoiceDialerActivity uses the more
modern system of using dialogs, which automatically
brings down and recreates the dialog upon orientation
changes. The BluetoothVoiceDialerActivity can't handle
this right now, it's state machine is much more
complicated. For now, it just forces itself to be in
protrait mode all of the time.

Bug: 2515380
The problem here was that the VoiceDialer app was assuming
that the packageName of a component can be derived by
dropping the last token of the className. Apparently this
is not true, the packageName as far as the packageManager
is not the name of the package in the java sense.
Now when adding all of the "open" entries to the grammar,
the CommandRecognizerEngine adds both the package name
and the class name, separated by "/".

When the BluetoothVoiceDialer is about to place a call, it uses Text To Speech
to indicate which contact is about to call. Prior to this change, it would
just place the call after waiting a few seconds, which did not always line up
with the end of the TTS utterance. Now it waits for the utterance to complete.
Similarly, when it is about to exit it says "goodbye" to let the user know
it's exiting, and it now waits for that utterance to complete before exiting.

Fix a bug in VoiceContacts that caused it to skip the first row
returned by that phone query. This meant that the first person/phone
would not be entered into the RecognizerEngine, and therefore was
impossible to call from the VoiceDialer.

Bug: 2432200
When using voicedialing without being able to see or interact with the
screen, it is more important to keep the number of matches small. There
is now a setting on the CommandRecognizerEngine called "minimizeResults".
If this is set, then the CommandRecognizerEngine will in most cases return
only the highest confidence result.
It will return multiple results only in the case where it is unsure which phone
to call a particular person on. When this occurs, the BluetoothVoiceDialer
will announce the person it is about to call, and which phone types are available
(i.e. home, work, mobile, other), then begin listening for the the user to
indicate which phone.

Bug: 2432200
This adds a new BluetoothVoiceDialerActivity,
because the flow for bluetooth is so different from the regular VoiceDialerActivity.
This involved breaking RecognizerEngine's direct dependence on VoiceDialerActivity to
make callbacks on. RecognizerEngine now makes callbacks on an interface called RecognizerClient,
which is implemented by several different helper classes for different reasons.
I've made RecognizerEngine an abstract base class, it handles some general setup, logging, etc.
but it is up to the subclasses to set up the grammar and handle the results when recognition
succeeds. There are currently two subclasses, the CommandRecognizerEngine recognizes
phrases to call people, dial numbers, and open applications. The YesNoRecognizerEngine recognizes
"yes" and "no".

Known issues as of this checkin:
* 8khz audio has not been validated, it's not certain that the Recognizer is getting a good audio stream.
* There is still a problem with audio routing, the TTS output switches randomly between the speaker and
the headset.
* only the simplest case is supported, there's not a clean solution when there are multiple
possible matches.
* there are cases where the activity really should wait for the TTS utterance to finish before
moving on.
* we don't have a solution for when the phone is locked and the user activates bluetooth voicedial.
* the flow may or may not be ideal, the "no matches, try again" option may not be useful. We will
let some people try this and then revisit the approach.
