    If you google for "Android SDK" you'll find it at once, and it contains Eclipse already setup, so that installing the whole thing is as easy as lying.

    can anyone help me to create databse.

    You'd better compose yourself and write it yourself if you need it. The program is not complicated (you can use SQLite in Android) and with Android tutorials (at the same site) it will not be hard. However it will really take some time so I doubt anyone is interested to do this stuff for you (at least without good payment).

    Your request involves a whole slew of things, all of which are in depth - not necessarily trivial - topics. My advice:
    a) Read Trail: JDBC(TM) Database Access (The Java™ Tutorials)
    b) consult MySQL :: The world's most popular open source database for MySQL related issues
    c) If you need an embedded database, use a more appropriate database to meet the task (my understanding is that at this time MySQL is not embedded)
    d) If you wish database info to be shared, you must set up an (or use a pre-set up) instance on a central server that can be accessed remotely by your app

    Looks like you specified wrong database name in your connection url or properties.

    import java.sql.Connection;
    import java.sql.Statement;
    import java.sql.DriverManager;
    import java.sql.ResultSet;
    import java.sql.ResultSetMetaData;
    import java.sql.SQLException;
    public class DisplayAuthors
    {
    //database URL
    static final String DATABASE_URL= "jdbc:mysql://localhost/vehiclinfo";

    //launch application
    public static void main(String args[])
    {
    Connection connection = null;
    Statement statement = null;
    ResultSet resultSet = null;
    try
    {
    connection = DriverManager.getConnection(DATABASE_URL,"root","r oot");
    statement = connection.createStatement();
    resultSet = statement.executeQuery("SELECT ID,LicenseNumber,Model,Yearofreg FROM details");
    ResultSetMetaData metaData = resultSet.getMetaData();
    int numberOfColumns = metaData.getColumnCount();
    System.out.println("details Table of vehicleinfo Database:\n");
    for (int i = 1;i <= numberOfColumns; i++ )
    System.out.printf("%-8s\t",metaData.getColumnName(i));
    System.out.println();
    while (resultSet.next())
    {
    for(int i = 1;i<= numberOfColumns; i++)
    System.out.printf("%8s\t",resultSet.getObject(i));
    System.out.println();
    }
    }
    catch(SQLException sqlException)
    {
    sqlException.printStackTrace();
    }
    finally
    {
    try
    {
    resultSet.close();
    statement.close();
    connection.close();
    }
    catch (Exception exception)
    {
    exception.printStackTrace();
    }
    }

    }
    }

    Data connections --->new -->select MySQL-->name vehicleinfo --> set path for jdbc driver --> give username and password of databse ---> Test connection
    Then i got ping failed error
