-/**
- * Provides access to network usage history and statistics. Usage data is collected in
- * discrete bins of time called 'Buckets'. See {@link NetworkStats.Bucket} for details.
- * <p />
- * Queries can define a time interval in the form of start and end timestamps (Long.MIN_VALUE and
- * Long.MAX_VALUE can be used to simulate open ended intervals). By default, apps can only obtain
- * data about themselves. See the below note for special cases in which apps can obtain data about
- * other applications.
- * <h3>
- * Summary queries
- * </h3>
- * {@link #querySummaryForDevice} <p />
- * {@link #querySummaryForUser} <p />
- * {@link #querySummary} <p />
- * These queries aggregate network usage across the whole interval. Therefore there will be only one
- * bucket for a particular key, state, metered and roaming combination. In case of the user-wide
- * and device-wide summaries a single bucket containing the totalised network usage is returned.
- * <h3>
- * History queries
- * </h3>
- * {@link #queryDetailsForUid} <p />
- * {@link #queryDetails} <p />
- * These queries do not aggregate over time but do aggregate over state, metered and roaming.
- * Therefore there can be multiple buckets for a particular key. However, all Buckets will have
- * {@code state} {@link NetworkStats.Bucket#STATE_ALL},
- * {@code defaultNetwork} {@link NetworkStats.Bucket#DEFAULT_NETWORK_ALL},
- * {@code metered } {@link NetworkStats.Bucket#METERED_ALL},
- * {@code roaming} {@link NetworkStats.Bucket#ROAMING_ALL}.
- * <p />
- * <b>NOTE:</b> Calling {@link #querySummaryForDevice} or accessing stats for apps other than the
- * calling app requires the permission {@link android.Manifest.permission#PACKAGE_USAGE_STATS},
- * which is a system-level permission and will not be granted to third-party apps. However,
- * declaring the permission implies intention to use the API and the user of the device can grant
- * permission through the Settings application.
- * <p />
- * Profile owner apps are automatically granted permission to query data on the profile they manage
- * (that is, for any query except {@link #querySummaryForDevice}). Device owner apps and carrier-
- * privileged apps likewise get access to usage data for all users on the device.
- * <p />
- * In addition to tethering usage, usage by removed users and apps, and usage by the system
- * is also included in the results for callers with one of these higher levels of access.
- * <p />
- * <b>NOTE:</b> Prior to API level {@value android.os.Build.VERSION_CODES#N}, all calls to these APIs required
- * the above permission, even to access an app's own data usage, and carrier-privileged apps were
- * not included.

-/**
- * The Network Service Discovery Manager class provides the API to discover services
- * on a network. As an example, if device A and device B are connected over a Wi-Fi
- * network, a game registered on device A can be discovered by a game on device
- * B. Another example use case is an application discovering printers on the network.
- *
- * <p> The API currently supports DNS based service discovery and discovery is currently
- * limited to a local network over Multicast DNS. DNS service discovery is described at
- * http://files.dns-sd.org/draft-cheshire-dnsext-dns-sd.txt
- *
- * <p> The API is asynchronous, and responses to requests from an application are on listener
- * callbacks on a separate internal thread.
- *
- * <p> There are three main operations the API supports - registration, discovery and resolution.
- * <pre>
- * Application start
- * |
- * |
- * | onServiceRegistered()
- * Register any local services /
- * to be advertised with \
- * registerService() onRegistrationFailed()
- * |
- * |
- * discoverServices()
- * |
- * Maintain a list to track
- * discovered services
- * |
- * |--------->
- * | |
- * | onServiceFound()
- * | |
- * | add service to list
- * | |
- * |<----------
- * |
- * |--------->
- * | |
- * | onServiceLost()
- * | |
- * | remove service from list
- * | |
- * |<----------
- * |
- * |
- * | Connect to a service
- * | from list ?
- * |
- * resolveService()
- * |
- * onServiceResolved()
- * |
- * Establish connection to service
- * with the host and port information
- *
- * </pre>
- * An application that needs to advertise itself over a network for other applications to
- * discover it can do so with a call to {@link #registerService}. If Example is a http based
- * application that can provide HTML data to peer services, it can register a name "Example"
- * with service type "_http._tcp". A successful registration is notified with a callback to
- * {@link RegistrationListener#onServiceRegistered} and a failure to register is notified
- * over {@link RegistrationListener#onRegistrationFailed}
- *
- * <p> A peer application looking for http services can initiate a discovery for "_http._tcp"
- * with a call to {@link #discoverServices}. A service found is notified with a callback
- * to {@link DiscoveryListener#onServiceFound} and a service lost is notified on
- * {@link DiscoveryListener#onServiceLost}.
- *
- * <p> Once the peer application discovers the "Example" http service, and either needs to read the
- * attributes of the service or wants to receive data from the "Example" application, it can
- * initiate a resolve with {@link #resolveService} to resolve the attributes, host, and port
- * details. A successful resolve is notified on {@link ResolveListener#onServiceResolved} and a
- * failure is notified on {@link ResolveListener#onResolveFailed}.
- *
- * Applications can reserve for a service type at
- * http://www.iana.org/form/ports-service. Existing services can be found at
- * http://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xml
