<p>
There are several configuration options you can specify in
<code class="literal">LOCAL_CFLAGS</code> located in the
<code class="literal">Android.mk</code> file.
</p>
<div class="itemizedlist">
<ul type="disc">
<li>
<p>
BDBSQL_CONVERT_SQLITE
</p>
<p>
This option enables to convert SQLite database to
BDB SQL database format. See <a class="xref" href="build_android_intro.html#build_android_migrate" title="Migrating from SQLite to Berkeley DB">Migrating from SQLite to
Berkeley DB</a> for more
information.
</p>
</li>
<li>
<p>
BDBSQL_SHARE_PRIVATE
</p>
<p>
This flag is enabled by default and keeps all the
region files in memory instead of the disk. This flag
also implements database-level locking.
</p>
</li>
<li>
<p>
SQLITE_DEFAULT_CACHE_SIZE
</p>
<p>
SQLite provides an in-memory cache which you size
according to the maximum number of database pages that
you want to hold in memory at any given time. See
<a class="xref" href="build_unix_sql.html#config_sql" title="Changing Compile Options">Changing Compile Options</a>.
</p>
</li>
<li>
<p>
SQLITE_DEFAULT_JOURNAL_SIZE_LIMIT
</p>
<p> For SQLite, this pragma identifies the maximum size
that the journal file is allowed to be. Berkeley DB
does not have a journal file, but it writes and uses
log files. A new log file is created when the current
log file has reached the defined maximum size. This
flag defines the maximum size for a log file. Default
value is 10 MB for Berkeley DB SQL interface. </p>
</li>
<li>
<p>
SQLITE_HAS_CODEC
</p>
<p>
Causes the Berkeley DB SQL interface to be built
with encryption support. See <a href="../bdb-sql/sql_encryption.html" class="olink">SQL Encryption</a> in the
<em class="citetitle">Berkeley DB Getting Started with the SQL APIs</em> guide for
usage details.
</p>
</li>
</ul>
</div>
<p>
Hard-coded numbers in the build can be adjusted using the
following SQLite PRAGMA commands:
</p>
<div class="itemizedlist">
<ul type="disc">
<li>
PRAGMA cache_size
</li>
<li>
PRAGMA journal_size_limit
</li>
</ul>
</div>
<p>
You can configure most aspects of your Berkeley DB
environment by using the <a href="../api_reference/C/configuration_reference.html" class="olink">DB_CONFIG</a> file.
