question: public static boolean shouldLogSlowQuery ( long elapsedTimeMillis ) { int slowQueryMillis = Integer . parseInt ( System . getProperty ( "db.log.slow_query_threshold" , "-1" ) ) ; return slowQueryMillis >= 0 && elapsedTimeMillis >= slowQueryMillis ; }
target:  Determines whether a query should be logged. Reads the "db.log.slow_query_threshold" system property, which can be changed by the user at any time.  If the value is zero, then all queries will be considered slow.  If the value does not exist or is negative, then no queries will be considered slow. This value can be changed dynamically while the system is running. For example, "adb shell setprop db.log.slow_query_threshold 200" will log all queries that take 200ms or longer to run.
