android - Do I need to have a google map app pre-installed on the device to be able to run an app using the google API?

I am creating an app that uses the google API. I would like to know if i install that app on a mobile phone, will it require a gooogle map app pre-installed in the device to be able to use the map or it uses the internet to get the map from google or any other methods?

This my main.java:

package com.map.testing;

import android.os.Bundle;

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

public class main extends MapActivity {

/** Called when the activity is first created. */
MapController mControl;
GeoPoint GeoP;
MapView mapV; @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mapV = (MapView) findViewById(R.id.mapView);
mapV.displayZoomControls(true);
mapV.setBuiltInZoomControls(true);

double lat =  23.1;
double longi = 113.3;

GeoP = new GeoPoint((int)(lat*1E6), (int)(longi*1E6));

mControl = mapV.getController();
mControl.animateTo(GeoP);
mControl.setZoom(12);


}

@Override 
protected boolean isRouteDisplayed() {        
// TODO Auto-generated method stub 
return false; 
}

}

This my main.xml:

             android:id="@+id/mapView"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:enabled="true"
             android:clickable="true"
             android:apiKey="00_sJY0o9guZejQwsJOr8PPDHtMpnEB6LWFspjA"
             />

my manifest:

    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    

            android:name=".main"
        android:label="@string/app_name" >
