Sql database in unity for android application

Here below is my code for basic usage of sql database read write in unity. as it works in unity player,but when i port it for android it doesnt work in it. So please tell me where should i change in my code to work that for android applications.

1)file id dbAccess.js

#pragma strict
import System.Data;  //  import our  data class
import Mono.Data.Sqlite; //  import sqlite
import System.Collections.Generic;

    // variables for basic query access

        dbcmd = dbcon.CreateCommand(); // create empty command
        dbcmd.CommandText = q; // fill the command
        reader = dbcmd.ExecuteReader(); // execute command which returns a reader
        if(r) { // if we want to return the reader
            return reader; // return the reader
        }
    }

    // This returns a 2 dimensional ArrayList with all the
    //  data from the table requested
    function ReadFullTable(tableName : String) {

                lineArray.Add(reader.GetValue(i)); // This reads the entries in a row
