如何解决 Android 中的“无法充气”运行时错误？

Question

我的应用程序应该打开地图。我已经包含了播放服务，实现了片段并做了我能做的一切！但是，我在运行时遇到了“无法膨胀”的错误。

我将我的清单文件、布局文件和 logcat 错误。

清单

布局

android:layout_width="fill_parent"
android:layout_height="fill_parent"

tools:context="xyz.xyz.Home" >


        <fragment
            android:id="@+id/mapView"
            android:name="com.google.android.gms.maps.MapFragment"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"

            android:layout_marginTop="20dp"
            android:apiKey="GoogleAPIKEY//I Added a Key, I just do not feel comfortable to display it"
            android:clickable="true"
            android:enabled="true" />

</RelativeLayout>

Logcat

还有更多，但这些看起来很重要。此外，它所说的添加为元数据的内容也已添加，但仍在生成异常。

您的 Android SDK 中是否有 Google Play 服务 库？如果没有，请去检查http://developer.android.com/google/play-services/setup.html。 如果您想离线下载 Google Play 服务，请转至http://venomvendor.blogspot.com/2012/03/android-sdk-extras-by-google-inc.html。
