Both stats and policy make NMS calls that depend on bandwidth control
being enabled, so move enable/disable into NMS and drop calls when
disabled. This avoids throwing heavy ISE exceptions when disabled.
Only include recent data when writing NetworkStatsHistory as part of
dumpsys call. Introduce manual poll event for Settings UI.

When airplane mode is enabled and the phone is rebooted, Bluetooth
should not turn on. Previously the airplane mode setting was ignored
and only the Bluetooth enabled setting was used to determine whether
to enable Bluetooth at boot time. Now, both settings are checked.

Watch for network statistics to cross NetworkPolicy warning or limit,
and show notifications to user as needed. Currently checks during
any statistics update, but will eventually move to event registration
through netd when kernel supports.
Fixed accounting bug in getSummaryForNetwork(). Only apply UID policy
to applications; applying to system processes could break critical
services like RIL.

Define NetworkPolicy as cycle-reset day and warning/limit values, and
set/get through NetworkPolicyManager. Watch ConnectivityManager for
network connection events, and apply quota rules based on matching
interfaces. Policy service matches based on strong identity to support
IMSI-specific policy values.
Calculates remaining quota based on current stats recorded since the
last reset cycle day. Tests to verify edge cases around February.
Persist network and UID policies in XML, and restore on boot.

Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set
for stats tracking.
To avoid exposing internal complexity, INetworkStatsService calls use
general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.
Cleaned up Objects and Preconditions.

Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all
interfaces.)
Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.
Change-Id: I797ea49439fcc487cfe2cbc16703d4b91ceb9af6
The POLICY_REJECT_BACKGROUND policy requires that network traffic be
blocked when a UID goes into the background. Even if the UID has an
activity in the foreground, it's considered "background" if the screen
is turned off.
This changes watches for SCREEN_ON/OFF broadcasts, and rule generation
now observes screen state. It also introduces an observer pattern so
that ActivityManager doesn't directly know about NetworkPolicy, and
moves the service management into SystemServer.

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 ImageWallpaper wasn't watching for the desired dimensions to
change, at which point it needs to resize its surface.
- The system process has been running with the small dalvik heap
limit, which is too tight with these huge wallpapers; this would
cause switching wallpapers to eventually stop working as it
couldn't get the memory it needed to load the new one.
- The compatibility mode background surface had a bunch of issues,
such as moving its windows to the right by the window size to
make them disappear. This of course doesn't play well with the
now super-sized wallpaper surface. This code is re-worked to
not require such shenanigans.

UsbManager:
- is now a service retrievable via Context.getSystemService(Context.USB_SERVICE).
- provides support for returning a list all connected USB devices
- broadcasts ACTION_USB_DEVICE_ATTACHED and USB_DEVICE_DETACHED when devices
are added and removed from the USB host bus
UsbDevice:
- represents an attached USB device.
UsbInterface:
- represents an interface on a USB device
- devices may have multiple interfaces if they provide multiple
sets of functionality (for example, android phones typically have interfaces
for both USB mass storage and adb)
UsbEndpoint:
- represents an endpoint on a USB interface
- endpoints are used for sending or receiving data
(only in one or the other direction)
UsbRequest:
- encapsulates a send or receive request to be sent over an endpoint

Fixed a race condition during startup. We need to wait for the input
devices to actually be ready before trying to detect safe mode.
Fixed a problem during safe mode activation where we would try to add
the overlay window but the display was not initialized. Now we do it
after the system is ready.

There is now one SystemUIService, which starts the status bar service.
Pretty soon there will be other things running in here too. This way
we don't need to have each of them started by something individually.
This also moves the choice between tablet and phone status bar into
SystemUI.apk, which seems like a much better place for it.

NFC service is now an application service in packages/apps/Nfc.
NFC service is registered through ServiceManager.addService(), and the proxy
object NfcAdapter obtains a handle to it through ServiceManager.getService().
**Important** Had to add new symbols AID_NFC / NFC_UID / android.uid.nfc and
modify service_manager.c, Process.java and PackageManagerService.java in order
to force the com.android.nfc process to take a fixed uid, so that it can use
ServiceManager.addService().
Most of the JNI has moved to packages/apps/Nfc/jni. However NdefRecord and
NdefMessage require some in-process native code, so android_com_NdefMessage.cpp
and android_com_NdefRecord.cpp stay in frameworks/base/core/jni. They link to
a very small library libnfc_ndef.so that implements NDEF message parsing. This
has been added to core.mk so all devices (even without NFC hardware) can work
with NDEF data.

If something kills system_server before it completes its shutdown
action, the runtime will just restart giving the illusion that a reboot
for an OTA or something else has happened.
To prevent this, write a system property containing the reboot reason
before initiating the shutdown with all the services. If the
system_server is killed before it completes, the next time the main
thread of system_server starts up, it will immediately execute the
shutdown action.
