Using SupportMapFragment

The post "A simple example using Google Maps Android API v2" using com.google.android.gms.maps.MapFragment. It work on device run API 12 and above. For older API level, using com.google.android.gms.maps.SupportMapFragment.

SupportMapFragment on Nexus One running Android 2.3.6


Modify layout to replace com.google.android.gms.maps.MapFragment with com.google.android.gms.maps.SupportMapFragment.
<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.SupportMapFragment"/>

</RelativeLayout>


Modify main code to extend android.support.v4.app.FragmentActivity, rather than Activity. Otherwise, AndroidRuntime will be Caused by: java.lang.ClassNotFoundException: android.view.fragment in loader dalvik.system.PathClassLoader.
package com.example.androidmapsv2;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class MainActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

}
