connection pool = number of database connections opened when the app opens
a database. These pooled connections are used by readers only and they
use the sqlite write-ahead-logging option to increase reader
concurrency.
The size of this connection pool depends on the number of CPUs, RAM etc.
On most single-core devices, this can be set to 1.
But on some multi-core devices with more RAM, pool size can be
more than 1.
On a device with more resources, here are the results of a test (in
coretests/src/android/database/sqlite/SQLiteDatabaseTest.java)
which measures the reader-parallelism achieved for different connection
pool sizes.
connpool-size = 1
num xacts by writer = 467
num-reads-in-xact/NOT-in-xact by reader1 = 1358/14542, by reader2 = 1431/14269
connpool-size = 2
num xacts by writer = 473
num-reads-in-xact/NOT-in-xact by reader1 = 5703/35227, by reader2 = 6222/35898
connpool-size = 3
num xacts by writer = 542
num-reads-in-xact/NOT-in-xact by reader1 = 6531/32329, by reader2 = 6252/32728
connpool-size = 4
num xacts by writer = 578
num-reads-in-xact/NOT-in-xact by reader1 = 6009/32701, by reader2 = 5977/32953
connpool-size = 5
num xacts by writer = 547
num-reads-in-xact/NOT-in-xact by reader1 = 6554/31186, by reader2 = 5318/31022
connpool-size = 6
num xacts by writer = 534
num-reads-in-xact/NOT-in-xact by reader1 = 5317/31463, by reader2 = 5413/31537
connpool-size = 7
num xacts by writer = 549
num-reads-in-xact/NOT-in-xact by reader1 = 5396/28004, by reader2 = 5214/28496
seems like connection pool size of 3 is optimal on this device.

This constant is not public yet. Continuous autofocus should
behave differently in still camera and camcorder. In camcorder,
lens movement may be more smooth. And the triggers to start a
new focus search may be different. If there is a need,
FOCUS_MODE_CONTINUOUS_PHOTO can be added in the future.
