我尝试使用android api v2创建一个mapview。但是我的应用程序在设备中崩溃了。但是在模拟器中工作不会崩溃
这些是我得到的主要错误。我无法弄清楚问题是什么。请帮我。 我使用了androidhive的教程。

答案 0 :(得分：2)
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" />
