Android studio jDBC not connecting to the mysql server with jdbc

Question

my code is crashing when connecting to the mysql database in xampp server . im running my app in android emulator that come with android studio and i tried change my hostname url from 10.0.2.2 to my pc ip 192.168.some.thing.

I tried to debug my application i foundout that isconnectionstringsupported() saying that the url is not supported.

and this same code is working just fine in windows. I think the problem is in this line of code below i tried to change 10.0.2.2 to my pc ip address(192.168.1.12) but still no luck but i can able to access my phpmyadmin with these to address in browser. 10.0.2.2/phpmyadmin and 192.168.1.12/phpmyadmin working fine in android emulator browser.

THIS LINE MAY BE Culprit

static final String DB_URL = "jdbc:mysql://10.0.2.2/codeig";

and one more thing im not using any php code i just want to connect to server directly . HERE IS MY CODE

package com.managear.aiverreaver.managearlite.data.database.dbhelper;

import android.util.Log;

import com.managear.aiverreaver.managearlite.data.ManaUniData;
import com.managear.aiverreaver.managearlite.data.database.IDBHelper;
import java.sql.*;

public class MySqlDBHelper implements IDBHelper {

    static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
    static final String DB_URL = "jdbc:mysql://10.0.2.2/codeig";

    //  Database credentials
    static final String USER = "ashish";
    static final String PASS = "ashish";

    private boolean m_isMysqlPhp;

    public MySqlDBHelper(boolean m_isMysqlPhp)
    {
        this.m_isMysqlPhp = m_isMysqlPhp;
    }

    @Override
    public ManaUniData ReadDB() {
        if(m_isMysqlPhp)
        {

        }
        else
        {
            Connection conn = null;
            Statement stmt = null;
            try{
                //STEP 2: Register JDBC driver
                Class.forName("com.mysql.jdbc.Driver");

                //STEP 3: Open a connection
                Log.i("hello","Connecting to a selected database...");
                conn = DriverManager.getConnection(DB_URL, USER, PASS); // FIXME: After this line of code exception is firing
                Log.i("hello","Connected database successfully...");

                //STEP 4: Execute a query
                Log.i("hello","Creating statement...");
                stmt = conn.createStatement();

                String sql = "SELECT * FROM posts";
                ResultSet rs = stmt.executeQuery(sql);
                //STEP 5: Extract data from result set
                while(rs.next()){
                    //Retrieve by column name
                    int id  = rs.getInt("id");
                   /* int age = rs.getInt("age");
                    String first = rs.getString("first");
                    String last = rs.getString("last");
                    */

                    //Display values
                    Log.i("hello","ID: " + id);
                  /*  Log.i("hello",", Age: " + age);
                    Log.i("hello",", First: " + first);
                    Log.i("hello",", Last: " + last);
                    */
                }
                rs.close();
            }catch(SQLException se){
                //Handle errors for JDBC
                se.printStackTrace();
            }catch(Exception e){
                //Handle errors for Class.forName
                e.printStackTrace();
            }finally{
                //finally block used to close resources
                try{
                    if(stmt!=null)
                        conn.close();
                }catch(SQLException se){
                }// do nothing
                try{
                    if(conn!=null)
                        conn.close();
                }catch(SQLException se){
                    se.printStackTrace();
                }//end finally try
            }//end try
            Log.i("hello","Goodbye!");
        }//end main
