点击模拟器上的播放服务（谷歌地图api v2无法在模拟器中工作），我收到以下错误：

你的logcat清楚地说了

引起：java.lang.IllegalStateException：您的元数据标记   应用程序的AndroidManifest.xml没有正确的值   引起：java.lang.IllegalStateException：应用程序的AndroidManifest.xml中的元数据标记没有正确的值。预期4323000但找到0.您必须在元素中包含以下声明：
        04-17 14：59：51.881：E / AndroidRuntime（1057）：    预期4323000但找到0.您必须具备以下条件   元素内的声明：

尝试在<meta-data>文件中的<application>标记下添加manifest.xml代码，例如

<meta-data
 android:name="com.google.android.gms.version"
 android:value="@integer/google_play_services_version" />

让你的manifest.xml像这样

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

<meta-data android:name="com.google.android.gms.version"  
 android:value="@integer/google_play_services_version" />

</application>
