How to display the driving routes in Android Studio Google Maps V2

Question

well I have the latitude and longitude of 3 people, I need to get and display the route between my location and the other 3 like this:

enter image description here

I have a little data Base in my app with 3 contacts and my code is like:

package androiddatabase.app;

import android.content.Context;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.View;
import android.view.Window;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class RutasActivity extends FragmentActivity implements View.OnClickListener {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_ruta);

    GoogleMap mapa = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
    mapa.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    mapa.setMyLocationEnabled(true);
    mapa.getMyLocation();

    CargarContactos(this, mapa);

        //--------------------------------//
        //           GREETINGS            //
        //          FROM BOLIVIA!!!       //
        //              n_n               //
        //--------------------------------//
}

private  void  CargarContactos(Context context,GoogleMap mapa){
    myApp.DBManager manager = new myApp.DBManager(context);
    Cursor cursor = manager.CargarMapa();
    if (cursor.moveToFirst()) {
        do
        {
            if (cursor.getString(4).toString().contains("1")) {
                mapa.addMarker(new MarkerOptions()
                        .position(
                                new LatLng(Double.parseDouble(cursor.getString(2)),
                                        Double.parseDouble(cursor.getString(3)))
                        )
                        .title(cursor.getString(7) + " - " + cursor.getString(1))
                        .snippet("Fecha: " + cursor.getString(5) + " Monto: " + cursor.getString(6))
                        .icon(BitmapDescriptorFactory
                                .fromResource(R.drawable.familia)));
            }
            else
            {
                mapa.addMarker(new MarkerOptions()
                        .position(
                                new LatLng(Double.parseDouble(cursor.getString(2)),
                                        Double.parseDouble(cursor.getString(3)))
                        )
                        .title(cursor.getString(7) + " - " + cursor.getString(1))
                        .snippet("Fecha: " + cursor.getString(5) + " Monto: " + cursor.getString(6))
                        .icon(BitmapDescriptorFactory
                                .fromResource(R.drawable.amigos)));
            }
        }
        while(cursor.moveToNext());
    }

    cursor.close();
    manager.CloseManager();
}

}

and only can show the positions like this:

enter image description here

so how can I show or display the route in driving mode between my location and other points? I see any examples or tutorials but in someones examples exists differences between the libraries like:

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;

for ADT or Eclipse and

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

for Android Studio

or GeoPoint is the equivalent to LatLng?

or am I wrong in something or forget something, how can I put my LatLng objects from my database in an array for show the route? any help? thanks Guys

There is nothing in the Google Maps V2 SDK for driving directions. The other examples you are seeing are using Maps V1 (e.g., `com.google.android.maps.MapView`). Maps V1 also has nothing in it for driving directions, and Maps V1 was replaced by Maps V2. — CommonsWare, May 06 '14 at 23:37
thanks @CommonsWare so Android Studio which version of Maps use? or you know any way to help me some tutorial, I did Try with polygons but I need show on the street way the route — user_Dennis_Mostajo, May 06 '14 at 23:53
I think this old post is exactly what you need, please check it: http://stackoverflow.com/a/15053901/1468354 — Aboullaite, May 07 '14 at 00:25
"which version of Maps use?" -- your only option is Maps V2. — CommonsWare, May 07 '14 at 11:44

If you want to display route between two points, you need to use Google Directions API to retrieve sub points between 2 locations.

For example, you can get route between Toronto and Montreal as JSON with this url https://maps.googleapis.com/maps/api/directions/json?origin=Toronto&destination=Montreal

After getting these points you just have to put them onto map with map.addPolyline method.
