Android SDK Google Services Maps API V2出现错误

我无法在移动设备上运行该应用程序，因为我无法通过仿真器安装Google Play服务，因此没有调试功能。基本上我想从谷歌地图显示地图。我很确定我的问题出在我的XML中，因为它是唯一不会自动生成的东西。

表现：

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

        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"

        <activity

            android:label="Travel Buddy"
            android:theme="@android:style/Theme.NoTitleBar" >

            </intent-filter>

            </activity>


        <activity
            android:name="com.example.mytravelbuddy.Itinerary"
            android:label="Itinerary">
        </activity>
    <meta-data
    android:name="com.google.android.maps.v2.myApiKey"
    android:value="myApiKey"/>    
    </application>

    <uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<!-- The following two permissions are not required to use
     Google Maps Android API v2, but are recommended. -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

    <uses-permission android:name="android.permission.INTERNET" />

</manifest>

这是我的类的XML文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/RelativeLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="-100dp"
    android:layout_marginEnd="0dp"
    android:layout_marginTop="-20dp"
    android:measureAllChildren="false"
    android:minHeight="75dp"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".Itinerary" 
    xmlns:map="http://schemas.android.com/apk/res-auto">

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

这段代码有问题吗，因为我无法调试它。

编辑：这是我设法获得的logcat：
