我正在使用我老板的手机来测试我们在 iOS 上开发并转移到 android 的应用程序。

我已经按照这个教程在手机上运行时给出了标题中提到的错误。我读过 10 以下的 SDK 不支持地图，对吗？很不确定从这里做什么。代码：

我有 3 个选项卡作为片段加载，有问题的片段是：

注意：所有导入都是正确的

public class EventFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

      // Inflate the layout for this fragment
      View V = inflater.inflate(R.layout.event_layout, container, false);

        return V;
    }
}

在视图 xml 文件中：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/the_map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.MapFragment"
    map:cameraTilt="45"
    map:cameraZoom="14"
    />

一切都在清单中。当我删除它运行良好。这种事情有解决办法吗？

我认为您需要实现 SupportFragment 并且片段类需要是： class="com.google.android.gms.maps.SupportMapFragment"

地图工作（公平）从 API8 开始。但是您需要将您的应用程序与 链接google-play-servces_lib，这很可能在您的情况下没有完成。还要确保您在 Manifest 中设置了所有权限。最后，查看官方文档：https ://developers.google.com/maps/documentation/android/
