MainActivity.java:

package com.example.harta;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

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

activity_main.xml :

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

This is example from Googl. Why isn't this sample code working?

Try with "FragmentActivity" instead of "Activity". I had the same error. here is my code

public class MainActivity extends FragmentActivity {

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        SupportMapFragment fragment = new SupportMapFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, fragment).commit();
}}
