Introduce new ACTION_PICK_DIRECTORY that allows users to grant access
to an entire document subtree. Instead of requiring grants for each
individual document, this leverages new prefix URI permission grants
by defining new "via"-style URIs:
content://com.example/via/12/document/24/
This references document 24 by using a prefix grant given for
document 12. Internally, we use isChildDocument() to enforce that
24 is actually a descendant (child, grandchild, etc) of 12. Since
this is an optional API, providers indicate support with
Root.FLAG_SUPPORTS_DIR_SELECTION.
Extend DocumentsUI to support picking directories. Expose
createDocument() API to work with returned directories.
Offer to canonicalize via-style URIs into direct URIs, generating
exact permission grants along the way. Override openAssetFile()
to pass through CancellationSignal. Move testing code into ApiDemos.

All ContentProvider calls are currently blocking, making it hard for
an app to recover when a remote provider is wedged. This change adds
hidden support to ContentProviderClient to timeout remote calls,
treating them as ANRs. This behavior is disabled by default.
Update DocumentsUI to use a 20 second timeout whenever interacting
with a storage provider.

When restoring a persisted stack, such as last location or a location
where save occurred, freshen the DocumentStack to get the latest
details from backend, and ensure the path is still valid.
Filter Recent directories in create mode based on roots allowed by
incoming request.
Remember when user last picked an external app, and open drawer next
time user launches for GET_CONTENT.
Fix state list drawable ordering, and avoid clobbering Drawable
callback when wrapping in InsetDrawable; tricksy hobbitses!
Make grid items smaller to always fit two columns on phones. Draw
grid items all the way to screen edge; don't clip to padding. Better
error message when folder creation failed. Show Recents in grid mode
when picking any visual content, not just images.

Fixed text colors to match spec. Behold The Greyening! Centered
loader spinner in grid mode. Show multiple lines in status messages.
Add string descriptions. Fix bug where toggling size setting didn't
kick a UI rebind.

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.

Implement EXTRA_HAS_MORE and EXTRA_REQUEST_MORE contract with
document providers. Providers can include EXTRA_HAS_MORE when
additional data is available with additional cost, such as a network
request.
Listen to content changes based on returned cursor instead of
original Uri. Include a test backend to exercise. UX still under
development.

In manage mode, touching launches a VIEW intent for the file. Also
adds actions for sharing and deleting.
Move roots and thumbnail caches into Application object, and flush
cache when thumbnail size changes. Listen for package changes and
broadcasts that should invalidate our roots cache.
Pick default grid/list mode based on provider hint.

Document browser now takes over all GET_CONTENT requests that request
openable Uris. It shows both storage backends and includes other apps
that respond to GET_CONTENT. Only grants transient read permissions.
Better guarding against throwing storage backends. Send sort order
and local-only hinting to backends.
Require that OPEN/CREATE_DOC users include openable category.

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.

Move storage roots into a fragment, since it's not a drawer on
tablets. Cluster and sort roots when displaying. SectionedListAdapter
to make clustered roots easier to manage. Add docs for root types.
Move roots cache into separate class to make it easier to share.

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
producing a derivative work of a Cursor.
Split data model classes into separate files.

Introduce XML metadata for storage backends, used to indicate if
custom roots should be queried, and provide any custom MIME type
icons inside that backend.
Parse metadata and resolve custom icons in UI.

Move backend root exploration into sliding drawer, and adjust action
bar when moving between modes. Moves sorting into action bar spinner
instead of separate dialog. Also add initial search support.

Extract mode information into DisplayState which is now consistent
across directory traversal. Use grid mode by default when working
with images. Dialog to switch sort order.
Add testing UI to exercise until we have real clients.

When caller has specified that multiple documents are okay, enable
multi-select action mode. Currently only allows document selection,
not directories. Returns multiple documents through ClipData.
Fix bug where GridView was stuck with 2 columns on tablets.

creation.

Continuing to flesh out storage backends by adding an external
storage document backend. Still rough, but it can traverse files
and directories.
Early pass at OPEN/CREATE_DOC picker UI, which offers to traverse
any known storage backends. Supports opening subdirectories and
returning a picked file.
