When a USB device or accessory is connected, the UsbService now asks the
user which application to associate with the device or accessory.
Applications interested in devices or accessories must specify the
devices they work with via meta-data attached to their manifest.
Permission to communicate with the device is assigned when the user chooses
the activity to use for the device.
The user has the option of clicking the "always use this application" checkbox
to make the assignment automatic in the future.
The user may later clear this preference and revoke permission for an application
to have permission to communicate with the device by clicking the "Clear defaults"
button for the activity in the Manage Applications panel in Settings.
Added class UsbResolveActivity (a subclass or ResolveActivity for choosing
an activity for a USB device or accessory)
Added UsbDeviceManager, which manages the mapping between USB devices/accessories
and applications, including default applications for devices and accessories,
and manages application permissions.
Add interface to allow Settings to clear device and accessory
preferences and permissions for an application.
Remove obsolete ACCESS_USB permission.
Add new signatureOrSystem MANAGE_USB permission to allow administrating
preferences and permissions.
Moved UsbService.java to a "usb" subdirectory, along with new classes
UsbResolveActivity and UsbDeviceManager.

The package manager now keeps track of whether an application is
stopped. There are new intent flags to control whether intent
filters in a stopped application will match the intent. This is
currently used in one place, sending broadcasts, so that stopped
apps can not be launched due to background processes.
The package manager during first init makes sure no applications
are in the stopped state. When new applications are installed,
that begin in the stopped state. When the activity manager is
launching a component of an application, it ensures the application
is taken out of the stopped state.
The "force stop" button in manage applications will now put an
application back in to the stopped state; it can't go back out
of the stopped state until one of its components is launched by
the activity manager.
There will probably be a few more places where we need to filter
stopped applications out of intent matches, but doing this for
broadcast is a very big first step.
This also introduces a new broadcast that is sent to an application
after it is replaced with a new .apk. But only if the app is not
in the stopped state. This makes it a lot easier for developers to
implement code to get their application back in proper running shape
after an upgrade.
Finally another new broadcast is added that is sent to a package's
installer at the first time it is launched. This allows the installer
to tell the package about it being installed only when it is first
actually used.

These extras are also accessable via the UsbDevice and UsbAccessory classes,
which are also included as extras.
Since you can't filter Intents based on extras there is no point in duplicating
this information as separate extras.

We were setting ACCELEROMETER_ROTATION to 0 before putting
in the proper USER_ROTATION value, and PhoneWindowManager's
content observer would eagerly rotate the screen to the last
locked orientation before re-rotating to the updated locked
rotation.
Now we set USER_ROTATION first. Additionally, the
content observer is now the only place we set
mUserRotation{,Mode} (previously we would race with it in
setUserRotationMode()).

Background scanning (preferred network offload) allows us the
host to sleep while the dongle monitors the presence of any
preferred networks. This allows us for significant power savings
since the system does not have to wake up often to initiate
a scan

Thumbnails are now requested separately, so we don't exceed the
IPC buffer size limit.
Also implement issue #3349553: Please provide a hook to intercept
fragment-breadcrumb clicks
And maybe fix issue #3439199: Music Notification does not turn on
when app switching out of Music app

USB accessories are peripherals that connect to android devices as a USB host.
When connected, the accessory will first identify itself to the android device
by sending manufacturer, product, accessory type and version strings
to the device, and then request the device to enter USB accessory mode.
The device will then enable the USB accessory kernel driver and disable
all other USB functionality except possibly adb
(adb can be used while the android device is connected to the PC
and the PC is running software that emulates a USB accessory)
The class android.hardware.UsbAccessory is used to describe the
currently attached USB accessory.
UsbAccessory contains the manufacturer, product, accessory type
and version strings to identify the accessory.
The accessory can be opened as a ParcelFileDescriptor, which can be used
to communicate with the accessory over two bulk endpoints.
The Intents UsbManager.USB_ACCESSORY_ATTACHED and
UsbManager.USB_ACCESSORY_DETACHED are broadcast when accessories are
connected and disconnected to the device. The USB_ACCESSORY_ATTACHED
contains a UsbAccessory object for the attached accessory as an extra.
The Intent also contains string extras for the manufacturer, product,
accessory type and version strings to allow filtering on these strings.
