When picking images or videos, hide the titles in recents, since the
thumbnails should speak for themselves. Also respect new flag that
allows a directory to request their titles be hidden.
Show directory icon hint in grid mode when showing a thumbnail, to
remind user it's a directory.
Filter directories out of recents. Hide most action bar icons on
phones, even when room. Only show drawer on first launch. Hide most
drawer headers to match spec.

for a root to indicate it's empty, and hide empty roots in UI unless
creating.
Define "Documents" public directory and storage backend to contain
files.

Shows as a faux dialog on larger tablets, since the normal dialog
themes from framework don't support action bars. Instead, this hacks
itself to look like a dialog with an InsetDrawable. Detects touches
in dim area to dismiss dialog.
Show all action bar icons on tablets, and roots panel is always
visible with a different shadow. Show settings in dialog. Allow mode
switches in recents.

Hide non-finished downloads from normal picker UI, but keep them
around in management mode. Uses a Uri query parameter and a hidden
API on DocumentsProvider.
Scale thumbnails to fit viewport, always show MIME icon while waiting
on thumbnails, and crossfade between them. Cancel thumbnail tasks
when views are recycled.
Filter directories out of search results for now. Also leave sort
ordering from backend intact, since it's custom ranking. Fix
SearchView interaction to dismiss properly and restore across
orientation and drawer state changes.
Hide most actions when drawer is open. Invalidate RootInfo cache
when locale changes. Apply sort ordering when showing recent create
directories. Hide recent summary string when icon is enough for user
to disambiguate.

Instead of persisting sort order per-directory, the order is now
sticky for that session. Any user selected sort order takes
precedence over an ordering hinted by a backend.
When a restored DocumentStack is untouched, the back key now leaves
the dialog, instead of popping from the restored stack.
Persist list/grid mode changes async.

Persist the last user-selected list/grid mode and sort order for
each directory. Remembered user choice always overrides provider
hinting.
Filter out recent documents that don't match requested MIME type, and
show recents in grid mode when picking images. Hide mode and sort
order in recents.
Add hinting flag for backend to indicate a directory would like to be
sorted by last modified. Include explicit root in DocumentStack and
clearly mark derived fields.

Change action bar to match current design; drawer is always available
and navigation dropdown is used to interact with current traversal
path in hierarchy. On first launch, show recents with drawer
expanded. On subsequent launches, resume from last location with
drawer closed. If last location root isn't applicable, then behave
like initial launch. Move sort order into action bar submenu.
Delete documents using contract. Use unstable provider when
inflating DocumentInfo from Uri.

When incoming request is for local-only content, or for ACTION_CREATE,
only include roots advertise those features.
Filters roots based on the allowed MIME types and the supported types
advertised by each root. This supports displaying Images and Audio
roots only when requesting those content types. Applies the same
filter when deciding which roots to query for recents.
Fixes advanced filtering instead of limiting to just devices. Update
sorting so that Recent always appears first. Add testing support for
LOCAL_ONLY.

Remember instance state across configuration changes, and enable
rotation. This remembers current modes and in-progress traversals.
Always finish action modes after launching an action. Fix sharing
by always putting Uris in extras, and always wrap in a chooser. Find
common MIME types when sharing multiple documents. Fix downloads
launching by following directory MIME type change.
Introduce "Durable" which is like Parcelable, but can be used for
both byte[] storage and Parcel transport. Make both DocumentInfo
and DocumentStack durable.
Disable recents until new behavior is implemented.

Combines related columns and constants onto the same class so they
are easier to discover. Move back to surfacing roots with columns
so they are consistent with documents.
Advanced roots are represented with a flag instead of distinct
types. Flags to indicate supporting of well-known media types,
instead of arbitrary an MIME filter. Reintroduce well-formed rootId
to support recents.
Always use the expanded version of "documents" in constants, methods,
and argument names.
Refactor DocumentProvider method names to clearly distinguish if
a single item or multiple could be returned, and of which type. Add
documentation to clearly define which methods have already been
overridden.

Using a contract class requires that a provider implement it exactly
with little help. This change introduces a DocumentsProvider abstract
class that provides a client-side implementation of the contract that
greatly reduces developer burden, and improves correctness.
This also moves to first-class DocumentRoot objects, and moves calls
with complex side effects to be ContentProvider.call() invocations,
offering more granular permission control over Uri operations that
shouldn't be available through Uri grants.
This new design also relaxes the requirement that root information be
burned into every Uri. Migrate ExternalDocumentsProvider and
DocumentsUI to adopt new API.

Since ContentProvider file operations can end up doing substantial
network I/O before returning the file, allow clients to cancel their
file requests with CancellationSignal.
Ideally this would only be needed for openFile(), but ContentResolver
heavily relies on openAssetFile() and openTypedAssetFile() for common
cases.
Also improve documentation to mention reliable ParcelFileDescriptors
and encourage developers to move away from "rw" combination modes,
since they restrict provider flexibility. Mention more about places
where pipes or socket pairs could be returned.
Improve DocumentsContract documentation.

Create documents manage mode to support Downloads and transient
storage devices. Locks user into requested backend root, and forces
file sizes on and sorting by last modified.
Separate API constants for Documents versus Roots, and give concrete
MIME types for roots.

Document browser now takes over all GET_CONTENT requests that request
openable Uris. It shows both storage backends and includes other apps

Add settings to show file sizes and advanced storage devices, both
disabled by default. Add sorting by size when enabled in settings.
Always show all documents, but only allow selection when they match
MIME filter. When creating, select entire filename on focus. When
creating, treat selected documents as replacement targets using that
exact Uri unless display name is changed.
Show available bytes for device roots. Show empty text label in
empty directories. Split grid backend and details into two separate
lines. Fix path label ordering when rendering recent directories.

versions of new DirectoryStack. Cleaner behavior around recents and
search, instead of treating them as pseudo-Documents.
More uniform item layouts between list and grid, including both date

clashing directory loaders by assigning unique numbers. Promote
list/grid switching up into activity.

Update DirectoryFragment to render List<Document>, making it more
general purpose. Feed it documents either from a backend Cursor or
after resolving fields from a recents Cursor. Start in recents when
no persisted stack available. Synthesize a root for recents.
Local directory filtering and sorting using predicates and
comparators, all performed on background thread. Introduce
UriDerivativeLoader which handles ContentObserver updates while

The same document may be present with different sematics under
multiple storage roots, so always reference using both ROOT_ID and
DOC_ID. This enables backends to revoke permissions for an entire

Allow storage backends to publish multiple roots into the UI, which
are defined by a directory GUID, type, and label details. Update
external provider to surface a primary external storage root, and
switch to burning file path into the returned GUIDs so they remain
durable.
Added insert, update, and delete support to external provider. Adds
file extensions to display names when needed to match MIME type.
Add flags for searching and deletion, and extras for Cursor
pagination. Add directory creation dialog to UI. Opening a document
always gives write access.
