Bug: 13927110
Change-Id: I2d96e50307611c269dcf47886cd4d976854da8fc
This patch uses the NativeLibraryHelper class to
match native libraries in an .apk package with
those listed in 'ro.cpu.abilist' property.
The result is stored in packages.xml and the
ApplicationInfo class.
This information will be used by the ActivityManager
to decide which zygote to use to launch the given
app.

Symptom: ANR report on wrong activity.
Root Cause:
KK changed resume behavior that will not update focus when only resume,
if the activity blocked, it may report ANR on previous focus.
By original concept, it will try to correct the ANR target,
but the stack of waiting(waitingVisible=true) activity may
different with current top stack.
If it gets key dispatch timeout, mResumedActivity and mPausingActivity
of its stack will be null becuase it is not top stack.
Then it is unable to change ANR target to the real no response activity.
Solution:
Use focused stack to get the real culprit.
Reproduce steps:
1.Launch an Activity X from launcher, press home key.
2.Launch X from launcher again, X blocks(sleeps 15sec) in onResume, press back key in the beginning of blocking duration.
3.ANR dialog shows launcher is no response.

The Zygote class is now in com.android.internal.os. It is
responsible for the vast majority of work before and after
the call to fork(). It calls back into the Runtime via
the new dalvik.system.ZygoteHooks class to allow the Runtime
to perform pre fork cleanup and post fork initialization.
The native code in Zygote.cpp is a direct and straightforward
port of the existing code in art. Most differences are
superficial, for example :
- We use C style logging (ALOGE) instead of stream based
logging.
- We call env->FatalError() instead of using LOG(FATAL)

When ensureActivitiesVisibleLocked goes through foreground activity
stack and reaches non-fullscreen activity, it sets showHomeBehindStack
variable to true.
If there is a fullscreen activity behind, showHomeBehindStack remains
unchanged, which causes Home application to be displayed anyway.
In this case user will see a fullscreen activity and Home activity
simultaneously.
To fix the issue we set showHomeBehindStack to false when we reach
fullscreen activity in the activity stack.
This was made visible by the following commit:

Symptom: ANR occurs on previous activity.
Root Cause:
In KK, when a background activity starts another existed background activity (bring to front),
if current focused stack is not the same as the stack of target starting activity,
it will still resume the top of target stack, even the top activity on the target stack may not the same as target activity.
And it will result incorrect focus, press back key will send to previous stack's top then popup ANR on previous activity:
"Reason: Waiting because no window has focus but there is a focused application".
By original code comment, it looks 'bring to front' should not happen in this issue case.
// If the target task is not in the front, then we need
// to bring it to the front... except... well, with
// SINGLE_TASK_LAUNCH it's not entirely clear. We'd like
// to have the same behavior as if a new instance was
// being started, which means not bringing it to the front
// if the caller is not itself in the front.
If the caller and target are in the same stask, it will just deliver new intent without changing task order (the same behavior as JellyBean).
So the patch concept is just to avoid to use target stack to resume top when caller and target are in different stack.
Solution: Do not allow to resume another stack top if non-top activity try to bring existed activity to front.
It may not be a good solution, just a reminder for the issue case.
Reproduce steps:
Assume A, B, C are different app tasks.
When the application stack is like:
Top C
B
A
#Case 1: Home is foreground
A starts B with NEW_TASK, C will resume, focus still stays at Home, and window order does not update.
Then press back key or volumn key will result ANR on Home.
#Case 2: App is foreground (Resumed activity is C)
A starts Home, Home will resume, focus still stays at C, and window order does did not update.
Then press back key or volumn key will result ANR on C.

Symptom: Unable to start any activity.
Root Cause: ActivityStack.mPausingActivity() points to a destroyed activity of a died process, so that ActivityStackSupervisor.allPausedActivitiesComplete() always returns false.
Solution: Set mPausingActivity to null in ActivityStack.cleanUpActivityLocked().
Reproduce steps:
a. Turn screen off.
b. A background service starts an activity X (in process X).
c. A background service starts a no-history activity Y (in process Y), but the main thread of Y was blocked.
d. A background service starts Y 3~4 times --> this causes am_failed_to_pause on X.
e. Main thread of Y is freed finally --> this causes Y crash for android.view.WindowManager$BadTokenException.
f. Turn screen on, X is shown on screen, but neither back key nor home key can work because mPausingActivity is Y.

When persistent process with Service restarts, ActivityManagerService
does not reset ProcessRecord#hasClientActivites to false
(because ProcessRecord of persistent process is continued using
after killing).
It disturbs updating LRU list in ActivityManagerService, and then,
when new process calls ActivityManagerProxy#publishContentProviders,
SecurityException happens because of no entry in the list.

- Introduce a boolean extra for intent TIME_CHANGED that
specifies if the user wants a 24 hour format or not.
- Have the ActivityManagerService inform running processes

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.

Issue detail:
Assume X, Y are non-fullscreen activities.
a.Home starts an activity X in task A in application stack.
b.X starts an activity Y in <task A> or <new task B>
c.Activity X will be invisible.
How to fix:
Because the function "isActivityOverHome" means an activity is able to see home.
But there may have many non-fullscreen activities between the top non-fullscreen activity and home.
If flag "behindFullscreen" is set, those middle activities will be invisible.
So it should only take care from who is adjacent to home.
Then check two flags frontOfTask(task root) and mOnTopOfHome for constraining the condition.

Code that expected a single top level element in an XML file
was doing something like :
while (type != START_TAG) { next(); }
This would loop forever when the XML being parsed was empty,
where each call to XmlPullParser.next() would return END_DOCUMENT.

If there is input to be handled during finish activity we can get a
keydispatching timeout ANR. The reason is that finish activity is some
times not possible, and the activity is instead put on a finish queue.
The activity will then be finished sometime in the future. When we add
the activity to the finish queue, key dispatching is paused, and there
is an ANR timer waiting for it to be resumed again. Since it can take a
long time before the activity is actually finished, we need to resume
the key dispatching to avoid the ANR.

In ActivityTask.moveTaskToBackLocked NullPointerException may occur
when moving back with only current Activity in stack. This due to a
condition that may trigger despite a TaskRecord being null and then
attempt accessing the TaskRecord.mOnTopOfHome variable.
TaskRecord task may be set to null when no resumed activity remain.
Resolved by assuring that flag mOnTopOfHome is instead set to false
for current TaskRecord in case where there are no remaining activities
above home.
The above bug has already been corrected in the following commit,
ada62fca51, but it does not set the
cottect value to mTopOfHome for the current taks, see below.
Variable mOnTopOfHome will not be set to false in situations where
stack is of size 1 or less and task is null, perhaps from already
having finished current activity.
To avoid current TaskRecord maintaining value mOnTopOfHome to true
after launching Home this variable is set to false.
Impact should not be major due to correction earlier that makes sure
that there is always a TaskRecord.mOnTopOfHome set to true above Home
activity but if not correctly set for current task still gives a
possibility of bad behavior.

BatteryStatsImpl can reset its collected data, including
removing a BatteryStatsImpl$Uid$Proc object. If a ProcessRecord
has a direct reference, then the battery stats for a process
will be recorded in an old Proc object and prevent GC, causing
a memory leak.

It looks like we could add services to the restart list because
they end up left in the process's list of running services after
they have been removed from the main activity list, and we can
trip up on them there when the app is being force stopped.

User removal or eviction inherently races with broadcast delivery. This
patch introduces a latest-possible recheck of the availbility of the
target application before attempting to send it a broadcast.
Once the process has actually been spun up the system is essentially
committed to presenting it as a running application, and there is no
later check of the availability of the app: the failure mode for
continuing to attempt delivery is a crash *in the app process*,
and is user-visible.
We now check the app+userid existence of the intended recipient
just prior to committing to launch its process for receipt, and
if it is no longer available we simply skip that receiver and
continue normally.

If a window claims to handle its own configuration change then we
won't destroy and recreate its window on a configuration change.
Normally that recreation triggers the first layout following
orientation change because mHaveFrame is false. Windows that handle
their own configuration changes never got a relayout pass following a
change in orientation.
This change passes the configuration changes that an application
handles into the AppWindowToken. If the app says it handles
orientation or screen size changes then a relayout will occur when the
configuration has changed.

Not clearing the service's app pointer.
Also fix this wtf where we were not clearing the started state of
a ServiceTracker when its process goes away. (This was like this

know the process is trying to restart. But now that have a new
explicit restarting strate, there is no need to leave it.)
