检查xml文件中的这一行，您可能有输入错误。

请检查清单文件中是否存在以下内容：

Binary XML file line #11: Binary XML file line #11: Error inflating class

并将xml布局设置为显示地图，如下所示：

   <meta-data
      android:name="com.google.android.maps.v2.API_KEY"
      android:value="your value" />
   <meta-data
      android:name="com.google.android.gms.version"
      android:value="@integer/google_play_services_version" />

---

不好的添加更多详细信息。请发布您的xml。您可以发布布局文件的代码吗？它清楚地表明您在代码中使用了自定义映射类，并且在文件中给出了错误的类名。除了在布局文件中提供自定义地图类名之外，还应该有什么？RelativeLayout xmlns:android=schemas.android.com/apk/res/android````删除分号xml文件中没有分号啊，我知道回答这个问题不是个好主意，我应该听从我的直觉

   <meta-data
      android:name="com.google.android.maps.v2.API_KEY"
      android:value="your value" />
   <meta-data
      android:name="com.google.android.gms.version"
      android:value="@integer/google_play_services_version" />

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