SQLiteDatabase openDatabase -- should take File for first parameter
instead of a String path
SQLiteDatabase.OpenParams.Builder -- make sure the javadocs says what
the default openFlags is and default idle connection timeout
SQLiteDatabase createInMemory -- throw if it has trouble instead of
returning null.

It allows apps to set time SQLite connection is allowed to be idle
before it is closed and removed from the pool.

Idle connections are now closed 30 seconds after being returned to the
pool. In-memory databases and databased with attached databases
are exempt from closing idle connections.
The new behavior is enabled on all devices (temporarily).
Use "setprop persist.debug.sqlite.close_idle_connections 0" to disable
Test: manual - devices boots, no app crashes, auth(accounts.db) works

[Cause of Defect]
In the ContentObserver callback procedure, the binder thread
has no sync mechanism with handler thread.
The ContentObserver#onChange method can get called after
ContentResolver#unregisterContentObserver called in the
very low probability.

Modified SQLiteDatabase to allow passing lookaside configuration to its
static initializer. Encapsulated config in OpenParams and added an
overloaded version of openDatabase with the new parameter.
Configuration is changed in SQLiteConnection::nativeOpen, immediately
after opening the database since lookaside memory configuration can only
be changed when no connection is using it.
Added SQLiteOpenHelper.setLookasideConfig method that is called from
the constructor of the subclass.

Auto-paging of cursors is being removed in favor of a support lib component.
Rationale:
1) Auto-paging as implemented has potential to negatively impact system health.
2) Similar functionality w/o system health concerns can be provided
specific to RecyclerView.
Test: Removed. CTS coverage updated.

StatFs.restat() and the StatFs constructor can throw
IllegalArgumentException. This was not previously documented;
not all callers took this into account, for example:
http://r.android.com/251290
This CL adds documentation to those methods. It also adds
comments to two of the callers.
Separately from this CL, we may in addition consider adding
new API StatFs.checkedRestat() and StatFs.checkedCreate()
or similar that throw IOException; we cannot change the
existing constructor and method since they are public.
Test: Checked that "make" still completed successfully.

SQLite's internal representation for booleans is an integer with a value
of 0 or 1, so without this check, boolean values obtained via
DatabaseUtils#cursorRowToContentValues will always return false.

Added a convenience mechanism to delete the whole database if it is of
a version that is so old that the application does not want to support
upgrading it. SQLiteOpenHelper now automatically deletes such a database
and creates a fresh one with the newest version provided. A callback
onBeforeDelete is added if the application wants to collect some data
from the db before it is deleted.
Test: Tested by upgrading contacts database using ContactsDatabaseHelper

The documentation incorrectly states that, "[insertWithOnConflict
returns] the primary key of the existing row if the input param
'conflictAlgorithm' = CONFLICT_IGNORE". Unfortunately, SQLite does
not provide such functionality.

Inefficient SQLite use can have non-obvious effects on performance. For
example, insert and update operations can trigger a surprising number of
fsync() calls, especially if they're not grouped together into
transactions.
Add tracepoints around SQLite operations, to make it easier to pinpoint
their effects on the rest of the system.

The existing code exits the column-filling loop immediately but
may continue to try to fill rows. Ordinarily this should fail
too but it's possible for the process to continue and then
blow up a little later. Fixed this problem by exiting the row-
filling loop promptly.

Do not cache compiled regular expression and date formatter. Both
cannot be compile-time created, are expensive at preloading time,
and only used in the rare case of dumping the connection (mainly
