ff2577da370f15b8288f547575c28393477d57b1 04-Apr-2012 Eric Laurent <elaurent@google.com> unhide API for synchronous audio capture.

unhide MediaSyncEvent class and AudioRecord.startRecording() method with synchronization
event allowing to start audio capture upon occurence of a specific event.
So far the only event defined is playback presentation complete but more events and synchronized
playback/capture methods could be defined in the future.

505e5c8859f596ed58489be565d6e029314b2ac8 30-Mar-2012 Eric Laurent <elaurent@google.com> implemented synchronous audio capture

Added the infrastructure to support the synchronization of playback and
capture actions on specific events.
The first requirement for this feature is to synchronize the audio capture
start with the full rendering of a given audio content.
The applications can further be extended to other use cases
(synchronized playback start...) by adding new synchronization events and
new synchronous control methods on player or recorders.

Also added a method to query the audio session from a ToneGenerator.

Added getAudioSessionId() method to AudioRecord class so that applications can
retrieve the AudioRecord's session ID and attach audio pre processes.

9cc489a2196e449dbe090ad9bdbc5cedd0b8334f 05-Dec-2009 Eric Laurent <elaurent@google.com> Fix issue 2304669: VoiceIME: starting and canceling voice IME yields persistent "error 8" state on future attempts and breaks voice search.

Fixed AudioFlinger::openInput() broken in change ddb78e7753be03937ad57ce7c3c842c52bdad65e
so that an invalid IO handle (0) is returned in case of failure.
Applied the same correction to openOutput().
Modified RecordThread start procedure so that a failure occuring during the first read from audio input stream is detected and causes
the record start to fail.
Modified RecordThread stop procedure to make sure that audio input stream fd is closed before we exit the stop function.

Fixed AudioRecord JAVA and JNI implementation to take status of native AudioRecord::start() into account
and not change mRecordingState to RECORDSTATE_RECORDING if start fails.

4bc035a65cac177be9294e69f110497e3b6e34e6 22-May-2009 Eric Laurent <elaurent@google.com> Fix issue 1846343 - part 1

This change is the first part of a fix for issue 1846343, :
- Added new enum values for input sources in AudioRecord and MediaRecorder for voice uplink, downlink and uplink+downlink sources.
- renamed streamType to inputSource in all native functions handling audio record.

A second change is required in opencore author driver and android audio input to completely fix the issue.
