+<p>The L Developer Preview extends the <a href="{@docRoot}guide/topics/providers/document-provider.html">Storage Access Framework</a> to let users select an entire directory subtree,
+giving apps read/write access to all contained documents without requiring user
+confirmation for each item.</p>
-<p>To get the absolute paths to directories on external storage devices where
-applications can store media files, call the new
-{@code android.content.Context.getExternalMediaDirs()} method. No
-additional
-permissions are needed by your app to read or write to the returned paths.
-In this context, "external storage devices" are those devices which the system
-considers to be a
-permanent part of the device, and includes emulated external storage and
-physical media slots such as SD cards in battery compartments.</p>
+<p>To select a directory subtree, build and send an
+{@code android.intent.action.OPEN_DOCUMENT_TREE} {@link android.content.Intent}.
+The system displays all
+{@link android.provider.DocumentsProvider} instances that support subtree selection,
+letting the user browse and select a directory. The returned URI represents access to the selected
+subtree. You can then use {@code DocumentsContract.buildChildDocumentsUriUsingTree()}
+and {@code DocumentsContract.buildDocumentUriUsingTree()} along with
+{@code ContentResolver.query()} to explore the subtree.</p>
-<p>You can bring up a system UI to allow the user to pick a directory subtree.
-To do so, send {@code android.intent.action.OPEN_DOCUMENT_TREE} in an
-{@link android.content.Intent}. If the call is successful, the system displays
-the {@link android.provider.DocumentsProvider} instances installed on the
-device for the user to select. When the user selects a directory from this UI,
-the system returns a URI representing the selected directory tree.</p>
+<p>The new {@code DocumentsContract.createDocument()} method lets you create
+new documents or directories anywhere under the subtree. To manage
+existing documents, use {@code DocumentsContract.renameDocument()} and
+{@code DocumentsContract.deleteDocument()}. Check {@code DocumentsContract.Document.COLUMN_FLAGS}
+to verify provider support for these calls before issuing them.</p>
-<p>If you want to access a document in an existing directory, call the
-{@code android.provider.DocumentsContract.buildDocumentViaUri()} method.
-Pass the method a URI representing the path to the parent directory, and the
-target document
-ID. The method returns a new {@link android.net.Uri} which your app can
-use to write media content with {@code DocumentsContract.createDocument()}.
+<p>If you're implementing a {@link android.provider.DocumentsProvider} and want
+to support subtree selection, implement {@code DocumentsProvider.isChildDocument()}
+and include {@code Documents.Contract.FLAG_SUPPORTS_IS_CHILD} in your
+{@code Root.COLUMN_FLAGS}.</p>
+
+<p>The L Developer Preview also introduces new package-specific directories on
+shared storage where your app can place media files for inclusion in
+{@link android.provider.MediaStore}. The new
+{@code android.content.Context.getExternalMediaDirs()} returns paths to these
+directories on all shared storage devices. Similarly to
+{@link android.content.Context#getExternalFilesDir(java.lang.String) Context.getExternalFilesDir()},
+no additional permissions are needed by your app to access the returned paths. The
