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 a file already exists on disk, try adding a counter suffix to
make a unique name. Move services near top of roots list, just below
recents. Remove "Documents" root.
Increase number of recents allowed from single provider, and add more
logging to diagnose wedged loaders.
When launching GET_CONTENT apps, wait for successful result before
relaying result; canceled requests now return to DocumentsUI.
Add CloseGuard to ContentProviderClients, since leaked instances can
keep the remote process alive.
Fix UI bug around trailing breadcrumbs. Fix bug that dropped Recents
from roots list. Add up action to Settings activity. Give our
activity a default icon while waiting for async roots to load.

Move all RootInfo queries to background threads to avoid janking
the UI. Update passes happen on spawed task, which swaps out updated
cache results when finished. Support partial updates when only a
single package/authority has changed. Watch for change notifications
for roots, since flags can change over time.
Ignore stopped packages when in background, but query them for roots
when launching any picker UI.
Optimize management launches by treating as one-shot requests that
don't need to wait for all RootInfo.

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.

Two hidden intents for managing roots and documents, used to support
Downloads UI. Touching an item tries launching as MANAGE_DOCUMENT
first before falling back to VIEW. Provide MIME type for roots.

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.

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.

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.

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.
Treat null sizes as unknown. Documents are always enabled in list
so that divider is drawn. Mark external storage file as writable.

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.
Change-Id: I44c62e8adb8ca7d4355510a13d1ba975196a2d29
Show recent directories in a separate fragment, and save as serialized
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
and size information, and originating storage root in recents. Avoid
clashing directory loaders by assigning unique numbers. Promote
list/grid switching up into activity.

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
root, such as when an account is removed.
Start building provider to remember recently accessed documents.
Change-Id: I75befa2e61393dec12fcc7fd27f631fcddae46fa
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.

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.
