Support any number of overlay packages. Support any target package.
UPDATED PACKAGE MATCHING
------------------------
In Runtime resource overlay, iteration 1, only a single overlay package
was considered. Package matching was based on file paths:
/vendor/overlay/system/framework-res.apk corresponded to
/system/framework-res.apk. Introduce a more flexible matching scheme
where any package is an overlay package if its manifest includes
<overlay targetPackage="com.target.package"/>
For security reasons, an overlay package must fulfill certain criteria
to take effect: see below.
THE IDMAP TOOL AND IDMAP FILES
------------------------------
Idmap files are created by the 'idmap' binary; idmap files must be
present when loading packages. For the Android system, Zygote calls
'idmap' as part of the resource pre-loading. For application packages,
'idmap' is invoked via 'installd' during package installation (similar
to 'dexopt').
UPDATED FLOW
------------
The following is an outline of the start-up sequences for the Android
system and Android apps. Steps marked with '+' are introduced by this
commit.
Zygote initialization
Initial AssetManager object created
+ idmap --scan creates idmaps for overlays targeting 'android', \
stores list of overlays in /data/resource-cache/overlays.list
AssetManager caches framework-res.apk
+ AssetManager caches overlay packages listed in overlays.list
Android boot
New AssetManager's ResTable acquired
AssetManager re-uses cached framework-res.apk
+ AssetManager re-uses cached 'android' overlays (if any)
App boot
ActivityThread prepares AssetManager to load app.apk
+ ActivityThread prepares AssetManager to load app overlays (if any)
New AssetManager's ResTable acquired as per Android boot
SECURITY
--------
Overlay packages are required to be pre-loaded (in /vendor/overlay).
These packages are trusted by definition. A future iteration of runtime
resource overlay may add support for downloaded overlays, which would
likely require target and overlay signatures match for the overlay to
be trusted.
LOOKUP PRIORITY
---------------
During resource lookup, packages are sequentially queried to provide a
best match, given the constraints of the current configuration. If any
package provide a better match than what has been found so far, it
replaces the previous match. The target package is always queried last.
When loading a package with more than one overlay, the order in which
the overlays are added become significant if several packages overlay
the same resource.
Had downloaded overlays been supported, the install time could have been
used to determine the load order. Regardless, for pre-installed
overlays, the install time is randomly determined by the order in which
the Package Manager locates the packages during initial boot. To support
a well-defined order, pre-installed overlay packages are expected to
define an additional 'priority' attribute in their <overlay> tags:
<overlay targetPackage="com.target.package" priority="1234"/>
Pre-installed overlays are loaded in order of their priority attributes,
sorted in ascending order.
Assigning the same priority to several overlays targeting the same base
package leads to undefined behaviour. It is the responsibility of the
vendor to avoid this.
The following example shows the ResTable and PackageGroups after loading
an application and two overlays. The resource lookup framework will
query the packages in the order C, B, A.
+------+------+- -+------+------+
| 0x01 | | ... | | 0x7f |
+------+------+- -+------+------+
| |
"android" Target package A
|
Pre-installed overlay B (priority 1)
|
Pre-installed overlay C (priority 2)

It wasn't possible to start apps installed in /vendor/app
on a device where /vendor was a symbolic link to /system/vendor.
This is currently the default configuration for android (see
init.rc)
During installation a dex file is created at:
/data/dalvik-cache/vendor@app@blah.blah.apk@classes.dex
But dalvik would fail to start this app with the following error:
I/dalvikvm( 3453): Unable to open or create cache for /system/vendor/app/blah.apk \
(/data/dalvik-cache/system@vendor@app@blah.blah.apk@classes.dex)
Note that dalvik were trying to start /system/vendor/app while the
app was installed in /vendor. There was a conflict between the
package manager and dalvik on how to interpret paths. This change
makes the package manager consistent with dalvik.

Changes in this patch include
[x] Long is used to store native pointers as they can
be 64-bit.
[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)
[x] AssetAtlasManager is not completely 64-bit compatible
yet. Specifically mAtlasMap member has to be converted
to hold native pointer using long. Added a TODO to
AssetAtlasManager.java to indicate the change required.

Symptom:
When press Home key to home screen, user is able to see the activity's window shown on top of wallpaper and below launcher(widgets).
Root Cause:
The ensureActivitiesVisibleLocked() is called pretty often (for example when a new process bound).
If the top activity "B" was finishing, then the previous activity "A" should be visible.
Therefore, the activity "A" window will be set to visible and then launched activity "A", but it does not updates the visible state in ActivityRecord for "A".
There has a timing issue that if a new activity "C" is started, "C" becomes the new top activity and be resumed.
In that case, Activity "A" window will remain visible even if it is behind a full screen activity "C" because the ActivityRecord.visble of "A" is still false, so the window visibility won't be update.
So when user press home key and back to launcher, the surface of activity "A" will be composed on top of wallpaper.
Solution:
Updates ActivityRecord.visible to true for "A". After "C" is started, the "A" will be called WindowManagerService.setAppVisibility() to set invisible, then called onStop() when execute ensureActivitiesVisibleLocked() again.

setLightLocked() will update mColor. This will cause the led to not be
turned off after the pulse.
When notificationManager starts a attention pulse the led will be kept
on. Since attention is of highest prio nothing can turn it off.
This is fixed by resetting mColor back to 0 after the call.

Since Kitkat, an app pre-loaded under /system/priv-app/ has

rebooted, privileged flag is unset from pkgFlags. This patch

packages.

It is not possible to send a broadcast before the system
boot is completed. If you do it anyway you will get an
IllegalStateException: Cannot broadcast before boot completed.
If a memory card is inserted or removed while the phone is
booting up, there is a risk that the MountService will try to
broadcast a storage intent too early, and cause the device
to crash.
Use FLAG_RECEIVER_REGISTERED_ONLY_BEFORE_BOOT to avoid
problems with too early broadcasts.

Transform DisplayManagerService into a SystemService and start cleaning
up other local services that it uses from window manager and input manager.
Clean up service thread initialization.
Remove unnecessary static variables from ActivityManagerService.
It's starting to become clear that we really need a better way to manage
service dependencies. Boot phases don't quite cut it.

Refactored SystemServer to get rid of a bunch of legacy cruft related
to how the ServerThread used to be started up.
Create system context first when system server starts. This removes
the tangled initialization order dependency that forced us to start
the activity manager service before most anything else.
Moved factory test related constants into the FactoryTest class.
Partially migrated Installer, ActivityManagerService, and
PowerManagerService to the new SystemService pattern. There's more
work to be done here, particularly around the lifecycle of the
power manager.

Got a little too aggressive about cleaning up service state; need to
avoid removing services from an app until we are in the second loop
doing the final cleanup, otherwise we can leave services around with
restarting their process.
