<include> yandex.map 时出错

有两个活动： Map Yandex。

public class MapsActivity extends AppCompatActivity {

private MapView mapview;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    MapKitFactory.setApiKey("censored");
    MapKitFactory.initialize(this);
    setContentView(R.layout.activity_maps);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    mapview = (MapView)findViewById(R.id.mapview);
    mapview.getMap().move(
            new CameraPosition(new Point(55.751574, 37.573856), 11.0f, 0.0f, 0.0f),
            new Animation(Animation.Type.SMOOTH, 0),
            null);
}
@Override
protected void onStop() {
    super.onStop();
    mapview.onStop();
    MapKitFactory.getInstance().onStop();
}

@Override
protected void onStart() {
    super.onStart();
    mapview.onStart();
    MapKitFactory.getInstance().onStart();
}

还有一个，开始加载屏幕。她的布局：

……

        <include layout="@layout/activity_maps"
            android:layout_width="match_parent"
            android:layout_height="300dp"/>

……

抛出错误：

android.view.InflateException: Binary XML file line #23 in com.rdv.slcard:layout/fragment_home: Binary XML file line #8 in com.rdv.slcard:layout/activity_maps: Error inflating class com.yandex.mapkit.mapview.MapView
Caused by: android.view.InflateException: Binary XML file line #8 in com.rdv.slcard:layout/activity_maps: Error inflating class com.yandex.mapkit.mapview.MapView
Caused by: java.lang.reflect.InvocationTargetException

我究竟做错了什么？

更新

第一个活动的布局

<com.yandex.mapkit.mapview.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".ui.maps.MapsActivity"
android:id="@+id/mapview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

更新 V.2.0

当然，您最好浏览片段，但这对夫妇说错话了

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/mapview"
android:name="com.yandex.mapkit.mapview.MapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.maps.MapsActivity"
/>

当我改变时：

<com.yandex.mapkit.mapview.MapView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".ui.maps.MapsActivity"
android:id="@+id/mapview"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

在常规 Button 或 TextView 上 - 一切都很好。我什么都听不懂。不可能是 Yandex 没有考虑到<include>
