The purpose of ICameraRecordingProxy and ICameraRecordingProxyListener is to
allow applications using the camera during recording.
Camera service allows only one client at a time. Since camcorder application
needs to own the camera to do things like zoom, the media recorder cannot
access the camera directly during recording. So ICameraRecordingProxy is a proxy
of ICamera, which allows the media recorder to start/stop the recording and
release recording frames. ICameraRecordingProxyListener is an interface that
allows the recorder to receive video frames during recording.
ICameraRecordingProxy
startRecording()
stopRecording()
releaseRecordingFrame()
ICameraRecordingProxyListener
dataCallbackTimestamp()
The camcorder app opens the camera and starts the preview. The app passes
ICamera and ICameraRecordingProxy to the media recorder by
MediaRecorder::setCamera(). The recorder uses ICamera to setup the camera in
MediaRecorder::start(). After setup, the recorder disconnects from camera
service. The recorder calls ICameraRecordingProxy::startRecording() and
passes a ICameraRecordingProxyListener to the app. The app connects back to
camera service and starts the recording. The app owns the camera and can do
things like zoom. The media recorder receives the video frames from the
listener and releases them by ICameraRecordingProxy::releaseRecordingFrame.
The recorder calls ICameraRecordingProxy::stopRecording() to stop the
recording.
The call sequences are as follows:
1. The app: Camera.unlock().
2. The app: MediaRecorder.setCamera().
3. Start recording
(1) The app: MediaRecorder.start().
(2) The recorder: ICamera.unlock() and ICamera.disconnect().
(3) The recorder: ICameraRecordingProxy.startRecording().
(4) The app: ICamera.reconnect().
(5) The app: ICamera.startRecording().
4. During recording
(1) The recorder: receive frames from ICameraRecordingProxyListener.dataCallbackTimestamp()
(2) The recorder: release frames by ICameraRecordingProxy.releaseRecordingFrame().
5. Stop recording
(1) The app: MediaRecorder.stop()
(2) The recorder: ICameraRecordingProxy.stopRecording().
(3) The app: ICamera.stopRecording().

o This patch allows us to use the logic from MediaMetadataRetriever to extract a thumbnail instead of extracting
the thumbnail from a fixed position (@500 ms).

These calls did not correctly handle some variants of the arguments,
which showed up when running in PTP mode.

This adds support for setting a SurfaceTexture as the MediaPlayer video
sink by using a ParcelSurfaceTexture object. The goal is to enable a
SurfaceTexture to pass through Binder (via ParcelSurfaceTexture) and then
be set on the MediaPlayer.

PTP mode will be implemented as a separate USB function instead.

o The intended failure happens if stop() call comes immediately after start() call
before any media data from the output of the encoder is received.

AudioService does not need to unconditionally stop virtual calls
when the audio mode is changed from normal. Only stop virtual calls
that have been started from AudioService.

The AudioManager API to control bluetooth SCO did not provide an easy way for
applications to handle SCO connection errors. When a request to activate SCO with
AudioManager.startBluetoothSco() failed, no state change was indicated via
AudioManager.ACTION_SCO_AUDIO_STATE_CHANGED intent. The application had to
implement a timeout to handle connection failures.
The API change consists in defining a new intent AudioManager.ACTION_SCO_AUDIO_STATE_UPDATED
and deprecate AudioManager.ACTION_SCO_AUDIO_STATE_CHANGED. The new intent
will broacast a new state CONNECTING when the SCO connection is initiated.
The application can monitor changes from CONNECTING to either CONNECTED or DISCONNECTED
states to detect connection success or failure.
An extra indicating the previous state is also added to the new intent.
Also improved BluetoothHeadset service management in AudioService. A disconnection
from the service is not considered as a device or SCO link disconnection. Instead, if the
service interface is not present when a request to activate SCO is received, an
attempt is made to reconnect to the service.

Replace config_emulateExternalStorage, config_externalStorageRemovable,
config_externalStoragePaths, config_externalStorageDescriptions and
config_mtpReserveSpaceMegabytes resources with an XML resource file
to describe the external storages that are available.
Add android.os.storage.StorageVolume class
StorageManager.getVolumeList() now returns an array of StorageVolume
