我对谷歌地图的实施完全困惑了一天半。我遵循了链接中提到的所有必要步骤。https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2
但是，所有时间我都会遇到以下提及的错误。我需要您的鹰眼经验。

你的logcat清楚地说
由以下原因引起：java.lang.IllegalStateException：应用程序的AndroidManifest.xml中的元数据标记没有正确的值。预期为4323000，但发现为0。元素中必须具有以下声明：
尝试使用文件中<meta-data>标记下的<application>标记添加Google Play服务版本，manifest.xml例如
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
让你manifest.xml喜欢
....<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>
