Android Agregar Maps v2 API a Master Detail Flow – Error al inflar el fragmento de clase

Estoy intentando agregar una vista de Google Maps usando la versión 2 de la API al flujo de detalles de Android Master. Por alguna razón, estoy recibiendo un error al inflar la excepción de fragmento de clase:

He creado un nuevo MapDetailFragment:

• Definición de un CameraUpdate con LatLngBounds con diferentes valores de relleno
• Android, ¿Cómo agregar opciones de mapas de Google desde el diseño XML?
• Obtenga GoogleMap del fragmento de ViewPager
• Google Maps v2 En cajas de fragmentos cuando se hace clic dos veces
• No cierre infoWindow en el mapa hecho clic. (Google Map Android API V2)

 package com.reading.trackitparent; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; import com.reading.trackitparent.dummy.DummyContent; /** * A fragment representing a single Item detail screen. This fragment is either * contained in a {@link ItemListActivity} in two-pane mode (on tablets) or a * {@link ItemDetailActivity} on handsets. */ public class MapDetailFragment extends Fragment { /** * The fragment argument representing the item ID that this fragment * represents. */ public static final String ARG_ITEM_ID = "item_id"; /** * The dummy content this fragment is presenting. */ private DummyContent.DummyItem mItem; /** * Mandatory empty constructor for the fragment manager to instantiate the * fragment (eg upon screen orientation changes). */ public MapDetailFragment() { } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (getArguments().containsKey(ARG_ITEM_ID)) { // Load the dummy content specified by the fragment // arguments. In a real-world scenario, use a Loader // to load content from a content provider. mItem = DummyContent.ITEM_MAP.get(getArguments().getString( ARG_ITEM_ID)); } } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.fragment_map_detail, container, false); // // Show the dummy content as text in a TextView. // if (mItem != null) { // ((TextView) rootView.findViewById(R.id.item_detail)) // .setText(mItem.content); // } return rootView; } } 

Y estoy tratando de utilizar el siguiente diseño:

 <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=".ItemDetailActivity" > <fragment xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.MapFragment" /> </RelativeLayout> 

ItemListActivity:

 package com.reading.trackitparent; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.FragmentActivity; /** * An activity representing a list of Items. This activity has different * presentations for handset and tablet-size devices. On handsets, the activity * presents a list of items, which when touched, lead to a * {@link ItemDetailActivity} representing item details. On tablets, the * activity presents the list of items and item details side-by-side using two * vertical panes. * <p> * The activity makes heavy use of fragments. The list of items is a * {@link ItemListFragment} and the item details (if present) is a * {@link ItemDetailFragment}. * <p> * This activity also implements the required {@link ItemListFragment.Callbacks} * interface to listen for item selections. */ public class ItemListActivity extends FragmentActivity implements ItemListFragment.Callbacks { /** * Whether or not the activity is in two-pane mode, ie running on a tablet * device. */ private boolean mTwoPane; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_item_list); if (findViewById(R.id.item_detail_container) != null) { // The detail container view will be present only in the // large-screen layouts (res/values-large and // res/values-sw600dp). If this view is present, then the // activity should be in two-pane mode. mTwoPane = true; // In two-pane mode, list items should be given the // 'activated' state when touched. ((ItemListFragment) getSupportFragmentManager().findFragmentById( R.id.item_list)).setActivateOnItemClick(true); } // TODO: If exposing deep links into your app, handle intents here. } /** * Callback method from {@link ItemListFragment.Callbacks} indicating that * the item with the given ID was selected. */ @Override public void onItemSelected(String id) { if (mTwoPane) { // In two-pane mode, show the detail view in this activity by // adding or replacing the detail fragment using a // fragment transaction. Bundle arguments = new Bundle(); arguments.putString(MapDetailFragment.ARG_ITEM_ID, id); MapDetailFragment fragment = new MapDetailFragment(); fragment.setArguments(arguments); getSupportFragmentManager().beginTransaction() .replace(R.id.item_detail_container, fragment).commit(); } else { // In single-pane mode, simply start the detail activity // for the selected item ID. Intent detailIntent = new Intent(this, ItemDetailActivity.class); detailIntent.putExtra(MapDetailFragment.ARG_ITEM_ID, id); startActivity(detailIntent); } } } 

He hecho referencia a los Libros de servicios de Google Play. Mi manifiesto parece así:

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.reading.trackitparent" android:versionCode="1" android:versionName="1.0" > <permission android:name="com.reading.trackitparent.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> <uses-permission android:name="com.reading.trackitparent.permission.permission.MAPS_RECEIVE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-feature android:glEsVersion="0x00020000" android:required="true" /> <uses-sdk android:minSdkVersion="15" android:targetSdkVersion="15" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <activity android:name="com.reading.trackitparent.ItemListActivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name="com.reading.trackitparent.ItemDetailActivity" android:label="@string/title_item_detail" > <meta-data android:name="android.support.PARENT_ACTIVITY" android:value=".ItemListActivity" /> </activity> <uses-library android:name="com.google.android.maps" /> </application> <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="xxxxxxxxxxxxxxxxxxxxxxxxxxx" /> </manifest> 

¡Realmente apreciaria cualquier ayuda!
