Android Google Map API v2 - Error Inflating Class Fragment android.view.InflateException

I am following Google Maps Android API v2 documentation to use maps in my application. I am getting error "" I have tried everything but still am not able to resolve it.

Here's my MainActivity.java

package com.example.maps;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends FragmentActivity {

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

This is the xml layout

<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
    xmlns:tools="http://ift.tt/LrGmb4"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >

  <TextView
        android:id="@+id/header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

 <fragment
          android:id="@+id/map"
          android:name="com.google.android.gms.maps.MapFragment"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_below="@+id/header"
          />

</RelativeLayout>

This is the error I'm getting in logcat
