21 /**
22  * The exception that is thrown when an application exposes a {@code file://}
23  * {@link android.net.Uri} to another app.
24  * <p>
25  * This exposure is discouraged since the receiving app may not have access to
26  * the shared path. For example, the receiving app may not have requested the
27  * {@link android.Manifest.permission#READ_EXTERNAL_STORAGE} runtime permission,
28  * or the platform may be sharing the {@link android.net.Uri} across user
29  * profile boundaries.
30  * <p>
31  * Instead, apps should use {@code content://} Uris so the platform can extend
32  * temporary permission for the receiving app to access the resource.
33  * <p>
34  * This is only thrown for applications targeting {@link Build.VERSION_CODES#N}
35  * or higher. Applications targeting earlier SDK versions are allowed to share
36  * {@code file://} {@link android.net.Uri}, but it's strongly discouraged.
