 * Public interface for managing policies enforced on a device. Most clients of this class must be

 * device owner. A given method is accessible to all device administrators unless the documentation

     * Activity action: Starts the provisioning flow which sets up a managed profile.

     * <p>A managed profile allows data separation for example for the usage of a
     * device as a personal and corporate device. The user which provisioning is started from and
     * the managed profile share a launcher.
     *
     * <p>This intent will typically be sent by a mobile device management application (MDM).
     * Provisioning adds a managed profile and sets the MDM as the profile owner who has full
     * control over the profile.
     *
     * <p>It is possible to check if provisioning is allowed or not by querying the method
     * {@link #isProvisioningAllowed(String)}.
     *
     * <p>In version {@link android.os.Build.VERSION_CODES#LOLLIPOP}, this intent must contain the
     * extra {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME}.
     * As of {@link android.os.Build.VERSION_CODES#M}, it should contain the extra
     * {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_COMPONENT_NAME} instead, although specifying only
     * {@link #EXTRA_PROVISIONING_DEVICE_ADMIN_PACKAGE_NAME} is still supported.
     *
     * <p>The intent may also contain the following extras:
     * <ul>
     * <li>{@link #EXTRA_PROVISIONING_ACCOUNT_TO_MIGRATE}, optional </li>
     * <li>{@link #EXTRA_PROVISIONING_SKIP_ENCRYPTION}, optional, supported from
     * {@link android.os.Build.VERSION_CODES#N}</li>

     * </ul>
     *
     * <p>When managed provisioning has completed, broadcasts are sent to the application specified
     * in the provisioning intent. The
     * {@link DeviceAdminReceiver#ACTION_PROFILE_PROVISIONING_COMPLETE} broadcast is sent in the
     * managed profile and the {@link #ACTION_MANAGED_PROFILE_PROVISIONED} broadcast is sent in
     * the primary profile.
     *
     * <p>From version {@link android.os.Build.VERSION_CODES#O}, when managed provisioning has
     * completed, along with the above broadcast, activity intent
     * {@link #ACTION_PROVISIONING_SUCCESSFUL} will also be sent to the profile owner.
     *
     * <p>If provisioning fails, the managedProfile is removed so the device returns to its
     * previous state.
     *
     * <p>If launched with {@link android.app.Activity#startActivityForResult(Intent, int)} a
     * result code of {@link android.app.Activity#RESULT_OK} implies that the synchronous part of
     * the provisioning flow was successful, although this doesn't guarantee the full flow will
     * succeed. Conversely a result code of {@link android.app.Activity#RESULT_CANCELED} implies
     * that the user backed-out of provisioning, or some precondition for provisioning wasn't met.
     *
     * <p>If a device policy management role holder (DPMRH) updater is present on the device, an
     * internet connection attempt must be made prior to launching this intent. If internet
     * connection could not be established, provisioning will fail unless {@link
     * #EXTRA_PROVISIONING_ALLOW_OFFLINE} is explicitly set to {@code true}, in which case
     * provisioning will continue without using the DPMRH. If an internet connection has been
     * established, the DPMRH updater will be launched, which will update the DPMRH if it's not
     * present on the device, or if it's present and not valid.
     *

    /**
     * Called by a device owner, profile owner of a managed profile or delegated app with
     * {@link #DELEGATION_NETWORK_LOGGING} to control the network logging feature.
     *
     * <p> Supported for a device owner from Android 8 and a delegated app granted by a device
     * owner from Android 10. Supported for a profile owner of a managed profile and a delegated
     * app granted by a profile owner from Android 12. When network logging is enabled by a
     * profile owner, the network logs will only include work profile network activity, not
     * activity on the personal profile.
     *
     * <p> Network logs contain DNS lookup and connect() library call events. The following library
     *     functions are recorded while network logging is active:
     *     <ul>
     *       <li>{@code getaddrinfo()}</li>
     *       <li>{@code gethostbyname()}</li>
     *       <li>{@code connect()}</li>
     *     </ul>
     *
     * <p> Network logging is a low-overhead tool for forensics but it is not guaranteed to use
     *     full system call logging; event reporting is enabled by default for all processes but not
     *     strongly enforced.
     *     Events from applications using alternative implementations of libc, making direct kernel
     *     calls, or deliberately obfuscating traffic may not be recorded.
     *
     * <p> Some common network events may not be reported. For example:
     *     <ul>
     *       <li>Applications may hardcode IP addresses to reduce the number of DNS lookups, or use
     *           an alternative system for name resolution, and so avoid calling
     *           {@code getaddrinfo()} or {@code gethostbyname}.</li>
     *       <li>Applications may use datagram sockets for performance reasons, for example
     *           for a game client. Calling {@code connect()} is unnecessary for this kind of
     *           socket, so it will not trigger a network event.</li>
     *     </ul>
     *
     * <p> It is possible to directly intercept layer 3 traffic leaving the device using an
     *     always-on VPN service.
     *     See {@link #setAlwaysOnVpnPackage(ComponentName, String, boolean)}
     *     and {@link android.net.VpnService} for details.
