* adding compatibility menu
* backup gravity
* set expanable=true if the screen size is hvga * density.
* added "supports any density" mode. I'll add sdk check later.
* disallow to catch orientation change event if the app is not expandable. This
was causing layout problem under non-expandable mode. I discussed this with Mike C
and we agreed to do this approach for now. We'll revisit if this causes problem to
a lot of applications.
This attribute is parsed by the PackageParser into ConfigurationInfo. The major
and minor version numbers are defined as the higher and lower order bits.
* Refactored Compatibility code
* Added CompatibilityInfo class
* Removed getApplicationScale from Context
* Added Resources#getCompatibilityInfo so that RootView can get the compatibility info w/o going through Context
* Expandable support
* Added expandable tag under manifest
* Old application w/o expandable is given the default screen size ([320, 480] x density).
* The non-expandable window is centered.
This allows content providers to use in-memory data to implement
ContentProvider.openAssetFile(), instead of just normal files
and sockets as before.
To test cross-process use of AssetFileDescriptors for MemoryFiles,
a test content provider and a client for it are added to
AndroidTests.
Fixes http://b/issue?id=1871731
This was required because we need a way to set the preferred activity for a
particular intent filter based on user selection (in our case the
ACTION_WEB_SEARCH intent filter for selecting the preferred search engine from
the list of available search engines providers). The current
addPreferredActivity call was not sufficient since it leaves the existing
preferred activities in the list and does not remove them, which this call
does.
Backups will be handled by launching the application in a special
mode under which no activities or services will be started, only
the BackupAgent subclass named in the app's android:backupAgent
manifest property. This takes the place of the BackupService class
used earlier during development.
In the cases of *full* backup or restore, an application that does
not supply its own BackupAgent will be launched in a restricted
manner; in particular, it will be using the default Application
class rather than any manifest-declared one. This ensures that the
app is not running any code that may try to manipulate its data
while the backup system reads/writes its data set.
PhoneStateListener events like LISTEN_CALL_STATE_CHANGED,
have privacy information like phone numbers and hence,
need to be protected with a permission. The permission
READ_PHONE_STATE is used for this purpose. Use the permission
trick to ensure backward compatability.
Now old applications will automatically be granted it. Also renamed it from
SDCARD_WRITE to WRITE_SDCARD to be consistent with our other permissions,
and re-arranged how we do targetSdkVersion to actually be usuable for this
kind of stuff.
Note that right now this results in basically all apps being given the
WRITE_SDCARD permission, because their targetSdkVersion is not set. I will
be dealing with that in a future change.
You can now use android:testOnly="true" to not allow your .apk to be installed
as a normal app. The only way to do so is with the pm command and giving the
-t option, which sets a new INSTALL_ALLOW_TEST flag when installing.
I also used this to clean up the install API... actually, mostly to hide
it, since it is not accessible to apps so shouldn't be in the SDK. We
will be doing some more work on it, so this will prevent adding yet
another backwards-compatibility-for-no-reason version.
Issue 1837610 Adding a Widget before Running the Associated App Causes a Force Close
We were not retrieving the shared libraries of an application when deliving a
broadcast to an explicit component.
Issue 1753079 loading class path of instrumented app into instrumentation may load wrong path when instrumented app shares process with other apps:
We were using the ApplicationInfo that was used to originally create the process, not the one that the
instrumentation is against.
This adds new attributes for specifying a targetSdkVersion and maxSdkVersion.
There is a new ApplicationInfo flag that is set if the application has set
its targetSdkVersion to the current platform or later. Also you can now
use a string for minSdkVersion and targetSdkVerion, to indicate you are
building against a development tree instead of an official platform.
This introduces a new class in the base platform for performing a clean
shutdown (which was copied from the classes in the policies). It
includes new features to send a shutdown broadcast for applications
to do cleanup, and ot have the activity manager pause the current
activity before proceeding with the shutdown. These facilities are
also use to write at the most recent stat files for sync, battery
and user activity.
The previous implementation used a database for storing all of its state, which could cause
a significant amount of IO activity as its tables were updated through the stages of a sync.
This new implementation replaces that in-memory data structures, with hand-written code
for writing them to persistent storage.
There are now 4 files associated with this class, holding various pieces of its state that
should be consistent. These are everything from a main XML file of account information that
must always be retained, to a binary file of per-day statistics that can be thrown away at
any time. Writes of these files as scheduled at various times based on their importance of
the frequency at which they change.
Because the database no longer exists, there needs to be a new explicit interface for
interacting with the sync manager database. This is provided by new APIs on IContentService,
with a hidden method on ContentResolver to retrieve the IContentService so that various
system entities can use it. Other changes in other projects are required to update to the
new API.
The goal here is to have as little an impact on the code and functionality outside of
SyncStorageEngine, though due to the necessary change in API it is still somewhat extensive.
This change adds a sketched outline of the backup system architecture, with
all of the major pieces represented other than client-side helpers for
specific types of data. IBackupManager and BackupService are public so that
we can write test apps against SDK-domain symbols from the outset.
What code exists in this change hasn't been tested and may crash. It's the
beginnings of the real implementation but of course is barely begun.
* Introduced ApplicationScale (may not be good name. CompatibilityScale? CanvasScale? Pls let me know if you have better idea)
* Changes to RootView / SurfaceView
- Makes the app believe it's running in the supported density/resolution.
- Makes the window manager believe it's running at the right density/resolution.
* Added methods to Rect/Event for scaling up/down.
Known issues:
* certain kind of images (such as nine patch for buttons) seesm to be loaded not by app, thus does not take the scale into account,
which, in turn, is causing layout issue.
* ZoomButton in MapView is rendered in wrong place
* Transparent region on Surface is not correct
* Specifying different densities in one process is not working.

There are three major classes of changes here:
- Avoid writing lines where their values are often empty, false, or some other typical thing.
- Use partial writes to the PrintWriter to avoid creating temporary strings.
- Use StringBuilder where we need to generate real String objects (and where possible cache the result).
Two new broadcasts, Intent.ACTION_POWER_CONNECTED and
Intent.ACTION_POWER_CONNECTED, that are issued when the device is plugged
and unplugged from USB or AC power. This pulls two changes from the
open-source Gerrit repo into the internal Donut codeline:
1241 fda6fae Added broadcasts for external power events.
9491 37f8ca1 Fix system service crash when booting while on battery power
The current.xml API description has also been updated to include the
new Intent fields; the new API was approved in the original OSS change.
in UriMatcher.match().
Before, every call to UriMatcher.match() called
Uri.getPathSegments() N + 1 times,
where N is the size of the list returned by
Uri.getPathSegments(). Since some of the implementations
of Uri.getPathSegments() are O(N), UriMatcher.match() was O(N^2).
This CL fixes the problem by calling uri.getPathSegments() once in
the beginning of match(). That should be safe since Uri is
immutable.
