+/**
+ * In the scrollable containers we want to clip the main axis sides in order to not display the
+ * content which is scrolled out. But once we apply clipToBounds() modifier on such containers it
+ * causes unexpected behavior as we also clip the content on the cross axis sides. It is
+ * unexpected as Compose components are not clipping by default. The most common case how it
+ * could be reproduced is a horizontally scrolling list of Cards. Cards have the elevation by
+ * default and such Cards will be drawn with clipped shadows on top and bottom. This was harder
+ * to reproduce in the Views system as usually scrolling containers like RecyclerView didn't have
+ * an opaque background which means the ripple was drawn on the surface on the first parent with
+ * background. In Compose as we don't clip by default we draw shadows right in place.

+ * not in the foreground; it will be recreated when the user next interacts with it. This has a few
+ * undesirable consequences:
+ *
+ * <p>1. It's impossible to recreate multiple activities at once, which means that activities in the
+ * background will observe the new configuration before they're recreated. If we keep them on the

+ * isn't free, and we'd rather do it when we're in the background than when the user is staring at
+ * the screen waiting to see us.
+ *
+ * <p>On API < 26, recreate() was implemented with a single call to a private method on
+ * ActivityThread. That method still exists in 26 and 27, so we can use reflection to call it and
+ * get the exact same behavior as < 26. However, that behavior has problems itself. When
+ * an Activity in the background is recreated, it goes through: destroy -> create -> start ->
+ * resume -> pause and doesn't stop. This is a violation of the contract for onStart/onStop,
+ * but that might be palatable if it didn't also have the effect of preventing new configurations
+ * from being applied - since the Activity doesn't go through onStop, our tracking of whether
+ * our app is visible thinks we're always visible, and thus can't do another recreation later.
+ *
+ * <p>The fix for this is to add the missing onStop() call, by using reflection to call into

+/**
+ * Builder class that can be used to facilitate the creation of a new {@link AppAuthenticator} which
+ * can be configured to meet the requirements of the test. Similar to the {@code AppAuthenticator},
+ * the static factory methods for this class require either an XML resource or {@link InputStream}
+ * containing the {@code app-authenticator} configuration allowing verification of your declared
+ * config as part of the test.
+ *
+ * <p>There are several options to configure the behavior of the resulting {@code AppAuthenticator}.
+ * <ul>
+ *     <li>{@link #setTestPolicy(int)} - This sets a generic test policy. {@link
+ *     #POLICY_SIGNATURE_ACCEPTED_FOR_DECLARED_PACKAGES} will cause the {@code AppAuthenticator}
+ *     to always return that a queried package has the expected signing identity as long as it is
+ *     explicitly declared in your configuration; that is, the package must be declared in a
+ *     {@code package} element within either an {@code expected-identity} or {@code permission}
+ *     element. {@link #POLICY_DENY_ALL} will cause the {@code AppAuthenticator} to always return
+ *     that a queried package does not have the expected signing identity regardless of its
+ *     declaration. These two policies can be used to verify good path and error path for
+ *     scenarios where the package names can be explicitly declared in the XML configuration.
+ *     <p>{@code POLICY_SIGNATURE_ACCEPTED_FOR_DECLARED_PACKAGES} is the default policy when no
+ *     other options are configured. When any of the other set methods (except for {@link
+ *     #setUidForPackage(String, int)}) are invoked they will set the policy to {@link
+ *     #POLICY_CUSTOM}.
+ *     </li>
+ *     <li>{@link #setSignatureAcceptedForPackage(String)} - This configures the {@code
+ *     AppAuthenticator} to always return that the specified package has the expected signing
+ *     identity. Note this still requires the {@code app-authenticator} have a path to verify
+ *     the provided package; that is, the package must either be explicitly declared in a
+ *     {@code package} element or fall under a {@code all-packages} element for the query being
+ *     performed. This is to ensure that a package being verified during the test could also be
+ *     successfully verified in production for the given query.
+ *     </li>
+ *     <li>{@link #setSigningIdentityForPackage(String, String)} - This sets an explicit
+ *     signing identity for the provided package; the signing identity should be
+ *     specified as the SHA-256 digest of the DER encoding of the signing certificate, similar
+ *     to how digests are specified in the {@code app-authenticator} configuration file. While
+ *     this can be used to set a signing identity to the expected value, this is more often
+ *     used to set the signing identity to a value that should not be accepted. For instance, a
+ *     test suite could have a test that verifies a key that is no longer trusted is never
+ *     added back to the configuration file.
+ *     </li>
+ *     <li>{@link #setPackageNotInstalled(String)} - This configures the {@code AppAuthenticator}
+ *     to treat the specified package as not installed on the device. Since a package that is not
+ *     installed can result in a different return code from the {@code AppAuthenticator} methods
+ *     this configuration can be used to verify an app's behavior when an expected app is not
+ *     installed on the device.
+ *     </li>
+ *     <li>{@link #setUidForPackage(String, int)} - The {@code AppAuthenticator} will
+ *     always verify the UID of the calling package matches the specified UID (or
+ *     {@link Binder#getCallingUid()} if a UID is not specified). By default this test {@code
+ *     AppAuthenticator} will use the result of {@code Binder#getCallingUid()} as the UID of all
+ *     queried packages. This method can be used to verify the expected behavior when a calling
+ *     package's UID does not match the expected UID.
+ *     </li>
+ * </ul>
