  • 
public final class SQLiteGlobal

    Provides access to SQLite functions that affect all database connection, such as memory management. The native code associated with SQLiteGlobal is also sets global configuration options using sqlite3_config() then calls sqlite3_initialize() to ensure that the SQLite library is properly initialized exactly once before any other framework or application code has a chance to run. Verbose SQLite logging is enabled if the "log.tag.SQLiteLog" property is set to "V". (per DEBUG_SQL_LOG).
