Android 在我的应用程序中显示空地图

我正在做一个应用程序，使用谷歌地图，但地图没有显示，我看到的只有空白方块

这是我的舱单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="fossa.damiano.mapsexample"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="17" />
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps" />
        <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>
    </application> 
</manifest>

以及main.xml：

<?xml version="1.0" encoding="utf-8"?>
<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" >

     <com.google.android.maps.MapView
         android:id="@+id/mapview1"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"
         android:apiKey="My Key" //I've already generated my Key
         android:clickable="true" />

</RelativeLayout>

我已经启用了internet连接，因此无法找出问题所在

更新
我已将谷歌地图的版本从1更新为2。
以下是更改：

            android:value="xxxxxxxxxxxxxxxxx"/>
    </application>

</manifest>

以及xml：

<?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" >

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

</RelativeLayout>

更新2

我做了另一个应用程序，只显示地图，它的工作
但是，当我尝试将该代码添加到我的应用程序时，它给出了上面显示的相同错误

---

那么，为什么映射不能同时在两个应用程序上工作呢？

从不推荐的API v1迁移到API v2的最简单方法是

删除所有与地图相关的代码

请点击此链接：

文件规定：

关于

MapFragment

类的使用：

仅当您的目标是API 12及以上版本时才使用此类。否则，请使用SupportMapFragment

---

你的min SDK是11，因此你应该使用

SupportMapFragment

或更改你的min SDK级别。

第一，你使用的是不推荐版本的google maps（v1），IIRC他们不接受它的任何新密钥，你应该使用maps v2。我以为我使用的是第二版本的maps。如何修复？v2在google play services中，您需要将google play services作为库项目导入到您的项目中才能使用它。搜索堆栈溢出关于如何做我已经更新了代码。看到这个答案吗
