Android - SupportMapFragment with GoogleMaps API 2.0 giving IllegalArgumentException

I am trying to use the latest Map API 2.0 provided for Android. I am using the Support Library as I want to support Android 2.2. Following is my code:

Main Activity class

public class MainActivity extends FragmentActivity {

    public FragmentManager fManager ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        fManager = getSupportFragmentManager();
        Button showMapButton = (Button) findViewById(R.id.showMapButton);
        showMapButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                loadMapFragment();
            }
        });
    }

    private void loadMapFragment() {
        MapPageFragment plotterFragment = new MapPageFragment();
        FragmentTransaction ft = fManager.beginTransaction();
        ft.replace(R.id.allFragmentsFrameLayout, plotterFragment);
        ft.addToBackStack(null);
        ft.commit();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

Main Activity layout file

<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" >

    <Button
        android:id="@+id/showMapButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Show Map"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="30dp"
        android:layout_alignParentTop="true" />


    <FrameLayout
        android:id="@+id/allFragmentsFrameLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentTop="true">
        <!-- Put fragments dynamically -->
    </FrameLayout>

</RelativeLayout>

Map Fragment Class

public class MapPageFragment extends SupportMapFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
                                         Bundle savedInstanceState) {
        super.onCreateView(inflater, container, savedInstanceState);
        return inflater.inflate(R.layout.map_fragment_layout, container, false);
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
    }
}

Map Fragment Layout

<?xml version="1.0" encoding="utf-8"?>
<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    class="com.google.android.gms.maps.SupportMapFragment"
    map:uiCompass="true"
    map:mapType= "normal"
    map:uiRotateGestures="true"
    map:uiScrollGestures="true"
    map:uiTiltGestures="true"
    map:uiZoomControls="true"
    map:uiZoomGestures="true" />

Android Manifest File

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mapfragmentexample"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

        android:required="true"/>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyA5FtIeLQ1gGUihZIZPQVi3Yz_0l4NG9PY"/>
    </application>

</manifest>

Everything is working fine for the first time. i.e. When I click on the Show Map button the map fragment gets loaded and displays the map. When I press back button, the map fragment is unloaded and I can see the Show Map button again.

I face an issue when I press the Show Map button again. I get the following error:

I am not getting where I am getting wrong or missing anything.

You can fix this, if you delete all nested fragments in onDestroyView(). Don't know if it is a proper solution.

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

And inflating them as usual in onCreateView()

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map, container, false);
}

You need to use getChildFragmentManager() to add SupportMapFragment not not through xml.

For "why", see official documentation: http://developer.android.com/about/versions/android-4.2.html#NestedFragments

Take a look at my answer here: https://stackoverflow.com/a/15512285/2183804
