    This{@link NetworkRequest} will live until released via - * {@link #unregisterNetworkCallback(NetworkCallback)} or the calling application exits, at - * which point the system may let go of the network at any time. - * - *

    A version of this method which takes a timeout is - * {@link #requestNetwork(NetworkRequest, NetworkCallback, int)}, that an app can use to only - * wait for a limited amount of time for the network to become unavailable. - * - *

    It is presently unsupported to request a network with mutable - * {@link NetworkCapabilities} such as - * {@link NetworkCapabilities#NET_CAPABILITY_VALIDATED} or - * {@link NetworkCapabilities#NET_CAPABILITY_CAPTIVE_PORTAL} - * as these {@code NetworkCapabilities} represent states that a particular - * network may never attain, and whether a network will attain these states - * is unknown prior to bringing up the network so the framework does not - * know how to go about satisfying a request with these capabilities. - * - *

The methods of the - * provided {@link NetworkCallback} will only be invoked due to changes in the best network - * matching the request at any given time; therefore when a better network matching the request - * becomes available, the {@link NetworkCallback#onAvailable(Network)} method is called - * with the new network after which no further updates are given about the previously-best - * network, unless it becomes the best again at some later time. All callbacks are invoked - * in order on the same thread, which by default is a thread created by the framework running - * in the app. - * - *

    This{@link NetworkRequest} will live until released via - * {@link #unregisterNetworkCallback(NetworkCallback)} or the calling application exits, at - * which point the system may let go of the network at any time. - * - *

    It is presently unsupported to request a network with mutable - * {@link NetworkCapabilities} such as - * {@link NetworkCapabilities#NET_CAPABILITY_VALIDATED} or - * {@link NetworkCapabilities#NET_CAPABILITY_CAPTIVE_PORTAL} - * as these {@code NetworkCapabilities} represent states that a particular - * network may never attain, and whether a network will attain these states - * is unknown prior to bringing up the network so the framework does not - * know how to go about satisfying a request with these capabilities. - * - *

The resolved - * IP addresses are programmed into netd via: - * - * updatePrivateDns() -> updateDnses() - * - * both of which make calls into DnsManager. - * [5] Upon a successful hostname resolution NetworkMonitor initiates a - * validation attempt in the form of a lookup for a one-time hostname - * that uses Private DNS. - * - * [B] Event: Private DNS settings are changed. - * Mechanics: - * [1] ConnectivityService gets notifications from its SettingsObserver. - * [2] handlePrivateDnsSettingsChanged() is called, which calls - * handlePerNetworkPrivateDnsConfig() and the process proceeds - * as if from A.3 above. - * - * [C] Event: An application calls ConnectivityManager#reportBadNetwork(). - * Mechanics: - * [1] NetworkMonitor is notified and initiates a reevaluation, which - * always bypasses Private DNS. - * [2] Once completed, NetworkMonitor checks if strict mode is in operation - * and if so enqueues another evaluation of Private DNS, as if from - * step A.5 above. - * - * @hide - */ -public class DnsManager { - private static final String TAG = DnsManager.class.getSimpleName(); - private static final PrivateDnsConfig PRIVATE_DNS_OFF = new PrivateDnsConfig(); - - /* Defaults for resolver parameters. */ - private static final int DNS_RESOLVER_DEFAULT_SAMPLE_VALIDITY_SECONDS = 1800; - private static final int DNS_RESOLVER_DEFAULT_SUCCESS_THRESHOLD_PERCENT = 25; - private static final int DNS_RESOLVER_DEFAULT_MIN_SAMPLES = 8; - private static final int DNS_RESOLVER_DEFAULT_MAX_SAMPLES = 64; - - /** - * Get PrivateDnsConfig. - */ - public static PrivateDnsConfig getPrivateDnsConfig(Context context) { - final int mode = ConnectivitySettingsManager.getPrivateDnsMode(context); - - final boolean useTls = mode != PRIVATE_DNS_MODE_OFF; - - if (PRIVATE_DNS_MODE_PROVIDER_HOSTNAME == mode) { - final String specifier = getStringSetting(context.getContentResolver(), - PRIVATE_DNS_SPECIFIER); - return new PrivateDnsConfig(specifier, null); - } - - return new PrivateDnsConfig(useTls); - } - - public static Uri[] getPrivateDnsSettingsUris() { - return new Uri[]{ - Settings.Global.getUriFor(PRIVATE_DNS_DEFAULT_MODE), - Settings.Global.getUriFor(PRIVATE_DNS_MODE), - Settings.Global.getUriFor(PRIVATE_DNS_SPECIFIER), - }; - } - - public static class PrivateDnsValidationUpdate { - public final int netId; - public final InetAddress ipAddress; - public final String hostname; - // Refer to IDnsResolverUnsolicitedEventListener.VALIDATION_RESULT_*. - public final int validationResult; - - public PrivateDnsValidationUpdate(int netId, InetAddress ipAddress, - String hostname, int validationResult) { - this.netId = netId; - this.ipAddress = ipAddress; - this.hostname = hostname; - this.validationResult = validationResult; - } - } - - private static class PrivateDnsValidationStatuses { - enum ValidationStatus { - IN_PROGRESS, - FAILED, - SUCCEEDED - } - - // Validation statuses of pairs for a single netId - // Caution : not thread-safe.
