+/**
+ * Base class for service that provides wrapping/unwrapping of the opaque blob needed for
+ * ResumeOnReboot operation. The package needs to provide a wrap/unwrap implementation for handling
+ * the opaque blob, that's secure even when on device keystore and clock is compromised. This can
+ * be achieved by using tamper-resistant hardware such as a secure element with a secure clock, or
+ * using a remote server to store and retrieve data and manage timing.
+ *
+ * <p>To extend this class, you must declare the service in your manifest file with the
+ * {@link android.Manifest.permission#BIND_RESUME_ON_REBOOT_SERVICE} permission,
+ * include an intent filter with the {@link #SERVICE_INTERFACE} action and mark the service as
+ * direct-boot aware. In addition, the package that contains the service must be granted
+ * {@link android.Manifest.permission#BIND_RESUME_ON_REBOOT_SERVICE}.
+ * For example:</p>
+ * <pre>
+ *     &lt;service android:name=".FooResumeOnRebootService"
+ *             android:exported="true"
+ *             android:priority="100"
+ *             android:directBootAware="true"
+ *             android:permission="android.permission.BIND_RESUME_ON_REBOOT_SERVICE"&gt;
+ *         &lt;intent-filter&gt;
+ *             &lt;action android:name="android.service.resumeonreboot.ResumeOnRebootService" /&gt;
+ *         &lt;/intent-filter&gt;
+ *     &lt;/service&gt;
+ * </pre>

+     * in the foreground.
+     *
+     * <p>This method will attempt to find the best network that matches the passed
+     * {@link NetworkRequest}, and to bring up one that does if none currently satisfies the
+     * criteria. The platform will evaluate which network is the best at its own discretion.
+     * Throughput, latency, cost per byte, policy, user preference and other considerations
+     * may be factored in the decision of what is considered the best network.
+     *
+     * <p>As long as this request is outstanding, the platform will try to maintain the best network
+     * matching this request, while always attempting to match the request to a better network if
+     * possible. If a better match is found, the platform will switch this request to the now-best
+     * network and inform the app of the newly best network by invoking
+     * {@link NetworkCallback#onAvailable(Network)} on the provided callback. Note that the platform
+     * will not try to maintain any other network than the best one currently matching the request:
+     * a network not matching any network request may be disconnected at any time.
+     *
+     * <p>For example, an application could use this method to obtain a connected cellular network
+     * even if the device currently has a data connection over Ethernet. This may cause the cellular
+     * radio to consume additional power. Or, an application could inform the system that it wants
+     * a network supporting sending MMSes and have the system let it know about the currently best
+     * MMS-supporting network through the provided {@link NetworkCallback}.
+     *
+     * <p>The status of the request can be followed by listening to the various callbacks described
+     * in {@link NetworkCallback}. The {@link Network} object passed to the callback methods can be
+     * used to direct traffic to the network (although accessing some networks may be subject to
+     * holding specific permissions). Callers will learn about the specific characteristics of the
+     * network through
+     * {@link NetworkCallback#onCapabilitiesChanged(Network, NetworkCapabilities)} and
+     * {@link NetworkCallback#onLinkPropertiesChanged(Network, LinkProperties)}. 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.
+     *
+     * <p>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.
+     *
+     * <p>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.
+     *
+     * <p>To avoid performance issues due to apps leaking callbacks, the system will limit the
+     * number of outstanding requests to 100 per app (identified by their UID), shared with
+     * all variants of this method, of {@link #registerNetworkCallback} as well as
+     * {@link ConnectivityDiagnosticsManager#registerConnectivityDiagnosticsCallback}.
+     * Requesting a network with this method will count toward this limit. If this limit is
+     * exceeded, an exception will be thrown. To avoid hitting this issue and to conserve resources,
+     * make sure to unregister the callbacks with
+     * {@link #unregisterNetworkCallback(NetworkCallback)}.

+     * @param handler {@link Handler} to specify the thread upon which the callback will be invoked.

+     *                        the callback must not be shared - it uniquely specifies this request.

+/**
+ * This class aims to persists the synthetic password(SP) across reboot in a secure way. In
+ * particular, it manages the encryption of the sp before reboot, and decryption of the sp after
+ * reboot. Here are the meaning of some terms.
+ *   SP: synthetic password
+ *   K_s: The RebootEscrowKey, i.e. AES-GCM key stored in memory
+ *   K_k: AES-GCM key in android keystore
+ *   RebootEscrowData: The synthetic password and its encrypted blob. We encrypt SP with K_s first,
+ *      then with K_k, i.e. E(K_k, E(K_s, SP))
