Correct check of is user running

Before the ActivityManagerService sends an intent or
starts an activity it checks if target user is in
mStartedUsers array.

When removing a non-owner user process the
UserStartedState instance will still be in mStartedUsers
array with mState STOPPING or SHUTDOWN.

This should be checked before sending an intent or start
an activity.

isUserRunningLocked(...) will interpret mState STOPPING
and SHUTDOWN as a non running user.

Fix NullPointerException in ListView

There is a NullPointerException in `handleHorizontalFocusWithinListItem()`
because `selectedView.findFocus()` returns null and then there is no null
check when when the assigned variable `currentFocus` is used, although
`View.findFocus()` states that it may return null.

Prevent ANR when broadcast receiver is killed

If the process of a BroacastReceiver is dying at the same time
as the system is trying to send an ordered broadcast to the
receiver, the system will try to start the process again. The
BroadcastQueue will store the BroadcastRecord in mPendingBroadcast
to be able to handle it again when the process is awake. A
timeout Message is posted to the handler of the BroadcastQueue.

As part of the shutdown sequence skipCurrentReceiver is called for
the ProcessRecord. This will check if there is a curReceiver set
for the application and make sure to finish the receiver.

Each of the foreground and background BroadcastQueues have their
own handler for managing broadcast timeouts. If the wrong
BroadcastQueue finishes the receiver, the pending timeout Message
will never be cancelled, leading to an ANR report for a receiver
that has already been finished.

Keep deleteIntent when copying Notification attributes

Ensures that any previously registered deleteIntent is retained after a call
to Notification.setLatestEventInfo().

Currently, a call to setLatestEventInfo() effectively erases a previously
registered Notification.deleteIntent, which results in the app never being
notified when the user dismisses the notification.

[ActivityManager] Ensure provider external access count will be released.

Sympton: Oom-adj of provider process will be always 0.

Root Cause: Exception happend in openContentUri
may not call removeContentProviderExternalUnchecked.

Flow:
application [MediaPlayer.setDataSource(Context context, Uri uri)]
    uri is invalid, IOException will be caught and below log will appear:
    "Couldn't open file on client side, trying server side"
    Continue to call setDataSource(String path, Map<String, String> headers)
 ->mediaserver [MediaPlayerService::Client::setDataSource]
    setDataSource(httpService, url, headers) calls openContentProviderFile
 ->system_server (ActivityManagerService) [openContentUri]
    Increase externalProcessNoHandleCount for media provider.
    Call [openFile] to media provider.
 ->android.process.media [check permission for openFile]
    enforceReadPermissionInner
 ->system_server [checkComponentPermission]
    Use mediaserver's uid to check READ_EXTERNAL_STORAGE
      -> not granted due to it is pure native process, not a known package.
    Throw security exception then the flow of openContentUri is broke.
    And externalProcessNoHandleCount is unable to decrease.

Application sample code:
 String invalidId = "54321";
 Uri externalUri = MediaStore.Files.getContentUri("external");
 Uri uri = Uri.withAppendedPath(externalUri, invalidId);
 mediaPlayer.setDataSource(mContext, uri);

Solution: Move removeContentProviderExternalUnchecked to finally block.

[ActivityManager] Prevent provider from been created twice.

Root Cause:
If a process which contains provider is starting but not
from accessing provider, e.g. service/activity/receiver,
its providers' will be created during handleBindApplication.
And before the process complete publish provider to
ActivityManagerService, if there is an access call to
process provider before the process completes publishing
providers to ActivityManagerService, then the providers
will be created again.

Solution:
Don't schedule install provider if the provider record
already exist and will be published later.

[ActivityManager] Avoid system server crash due to package removed

Symptom:
When application is not responding, an ANR dialog will shown.
In certain timing, user uninstall the application when the ANR
occurs, but before ANR dialog shown. The system server will crash
when looking up the errorReportReceiver because the package is removed.

Here shows how the exception occurs.

Reset killedByAm flag at attachApplicationLocked

ActivityManager reuses a process record object that killed
by him under some situation. That reused process record inherits
a killedByAm flag unexpectedly.
The killedByAm flag must be reset otherwise ActivityManager can't
judge the process can be killed or not.

Prevent showing immersive confirmation unexpectedly

By design, if the user presses the power key twice within 5 seconds
(panic), it will show immersive confirmation again at the next time
entering immersive mode.

But there is a bug on calculating the time between pressing the power
key. The time get from event.getDownTime() will stop when the device
is sleeping without being charged.

So here uses SystemClock.elapsedRealtime() instead.
