How to access Google Chrome browser history programmatically on local machine

Question

I want to write a simple program which shows my internet activity over a period of time (which site I visited, how many times and so on). I mostly use Google Chrome browser.

Answer 1

Since the original poster asked for a simple program, here it is. The program was adapted from the java workspace website (as credited in the code). You will need to change the argument for getConnection () to point to where the history files reside on your machine. The program compiles and runs on my Linux 2.6.39 environment:

 Download sqlite-jdbc-<>.jar from http://www.xerial.org/trac/Xerial/wiki/SQLiteJDBC, and
 compile: javac GetChromiumHistory.java
 run:     java -classpath ".:sqlite-jdbc-3.7.2.jar" GetChromiumHistory
*/

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

/**

public class GetChromiumHistory
{
    public static void main (String[] args) 
    {

    Connection connection = null;
    ResultSet resultSet = null;
    Statement statement = null;

    try 
        {
        Class.forName ("org.sqlite.JDBC");
        connection = DriverManager
            .getConnection ("jdbc:sqlite:/home/username/.config/chromium/Default/History");
        statement = connection.createStatement ();
        resultSet = statement
            .executeQuery ("SELECT * FROM urls where visit_count > 100");

        while (resultSet.next ()) 
            {
            System.out.println ("URL [" + resultSet.getString ("url") + "]" +
                        ", visit count [" + resultSet.getString ("visit_count") + "]");
            }
        } 

    catch (Exception e) 
        {
        e.printStackTrace ();
        } 

    finally 
        {
        try 
            {
            resultSet.close ();
            statement.close ();
            connection.close ();
            } 

        catch (Exception e) 
            {
            e.printStackTrace ();
            }
        }
    }
}
