Android : Calling map fragment second time getting error

I'm using map in fragment. First time its loading well but when I call it second getting error -

: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

xml code -

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <fragment
        android:id="@+id/mapfragment"
        android:layout_width="wrap_content"
        android:layout_height="200dp"
        android:layout_alignParentTop="true"
        android:layout_gravity="center_horizontal"
        class="com.google.android.gms.maps.SupportMapFragment" />

    <TextView
        android:id="@+id/title"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/mapfragment"
         />
</RelativeLayout>

java code -

   map = ((SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapfragment)).getMap();

referred many questions on stack tried below code also but not working -

public void onDestroyView() {
        super.onDestroyView(); 
        Fragment fragment = (getFragmentManager().findFragmentById(R.id.mapfragment));   
        android.support.v4.app.FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
    }
