App icon can be redered in various size and mipmap automatically
switches to high-resolution resources regardless of screen size when the
icon is rendered in large size.

There are a handful of core system services that collect data from
third-party ContentProviders by spinning them up and then caching the
results locally in memory. However, if those apps are killed due to
low-memory pressure, they lose that cached data and have to collect
it again from scratch. It's impossible for those apps to maintain a
correct cache when not running, since they'll miss out on Uri change
notifications.
To work around this, this change introducing a narrowly-scoped
caching mechanism that maps from Uris to Bundles. The cache is
isolated per-user and per-calling-package, and internally it's
optimized to keep the Uri notification flow as fast as possible.
Each Bundle is invalidated whenever a notification event for a Uri
key is sent, or when the package hosting the provider is changed.
This change also wires up DocumentsUI to use this new mechanism,
which improves cold-start performance from 3300ms to 1800ms. The
more DocumentsProviders a system has, the more pronounced this
benefit is. Use BOOT_COMPLETED to build the cache at boot.
Add more permission docs, send a missing extra in DATA_CLEARED
broadcast.

It opens a an alert dialog that tells user application X is requesting
access to folder Y on volume Z; if user accepts, it returns the proper
URI, otherwise it returns RESULT_CANCELED.
The requested path must satisfy the following requirements:
1.It's directory (getName()) must be one of the pre-definied folders on
Environment.
2.It's root (getParent()) must be a valid external storage root.
In order to satisfy #2, DocumentsUI calls the ExternalStorageProvider,
through a custom call() implementation.

Make the service operation agnostic, so we can also move delete operations to it.
In a followup change we'll see about adding support for multiple concurrent
operations. We'll need to evaluate how to do this in IntentService (which
serializes requests....a major limitation).

The existing management mode is too specific, and requires that
storage backends add queryChildDocumentsForManage(), etc. Instead,
to offer more natural browsing support, add a new BROWSE_ROOT intent.
It behaves mostly like MANAGE_ROOT, except that it doesn't mutate
its Uris with setManageMode(), and it shortcuts straight to VIEW on
clicked documents.
It can be launched like this:
$ adb shell am start -a android.provider.action.BROWSE_ROOT
-d content://com.android.externalstorage.documents/root/8405-1DFB
-c android.intent.category.DEFAULT
Also rename a MetricsConstants to make it clearer, and don't
auto-mount all emulated volumes.
Fix bugs around parceling of DiskInfo/VolumeInfo. Method to resolve
the best description for a VolumeInfo, which might need to fall
back to DiskInfo.
Add back "removed" volume state so we send broadcast when a volume
is destroyed, matching the expected public API behavior.

Move to using Toolbar for all actions. Drawer contains its own
Toolbar with separate title, and hamburger is always visible. Change
drawer items to match spec. Switching to Toolbar allows us to remove
nasty dialog-on-tablet hacks, yay! This also means we can finally
get real IME resizing support.
Move to using elevation for all shadows; this removes more nasty
hacks around drawing directory shadows.

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.

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.

Always finish action modes after launching an action. Fix sharing

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.
