/**
 * The exception that may be thrown when an application exposes a
 * {@code file://} {@link android.net.Uri} to another app.
 * <p>
 * This exception is a diagnostic tool for developers to identify situations
 * where {@code file://} Uris are being exposed. It is not always thrown when a
 * {@code file://} Uri is exposed, so it must not be relied on for security
 * purposes on any SDK version.
 * <p>
 * {@code file://} Uri exposure is discouraged since the receiving app may not
 * have access to the shared path. For example, the receiving app may not have
 * requested the {@link android.Manifest.permission#READ_EXTERNAL_STORAGE}
 * runtime permission, or the platform may be sharing the
 * {@link android.net.Uri} across user profile boundaries.
 * <p>
 * Instead, apps should use {@code content://} Uris so the platform can extend
 * temporary permission for the receiving app to access the resource.
 * <p>
 * This is only thrown for applications targeting {@link Build.VERSION_CODES#N}
 * or higher. Applications targeting earlier SDK versions are allowed to share
 * {@code file://} {@link android.net.Uri}, but it's strongly discouraged.
