A simple example using Google Maps Android API v2

Now, it's time to implement your code to add Google Maps Android API v2. Notice that you have to keep both your project and google-play-services_lib opened in Eclipse.

Please note that the code below is only useful for testing your settings in an application targeting Android API 12 or later, This code should not be used in a production application. 

Modify layout to add frqgment of com.google.android.gms.maps.MapFragment.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".MainActivity" >

    <TextView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerHorizontal="true"

        android:layout_centerVertical="true"

        android:text="@string/hello_world" />

    <fragment

        android:id="@+id/map"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        class="com.google.android.gms.maps.MapFragment"/>

</RelativeLayout>

Main code, actually nothing changed.

package com.example.androidmapsv2;

import android.os.Bundle;

import android.app.Activity;

public class MainActivity extends Activity {

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  setContentView(R.layout.activity_main);

 }

}
