Android YouTube视频播放在嵌套的viewpager中时引发未经授权的覆盖错误

我正在尝试将youtube播放器添加为双视图寻呼机中的弹出窗口，但该播放器停止提供以下错误：

YouTube video playback stopped due to unauthorized overlay on top of player. The YouTubePlayerView is not contained inside its ancestor android.support.v4.view.ViewPager{344132a VFED..... ........ 0,144-1080,1560 #7f0e00a1 app:id/pager_video}. The distances between the ancestor's edges and that of the YouTubePlayerView is: left: 1080, top: 809, right: -1080, bottom: 0 (these should all be positive).

及

我有三个xml文件：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.example.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        style="@style/customTabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:elevation="@dimen/tiny_dimen" />

</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

B.xml

C.xml

当我把C放在A里面，它工作得很好，但当我把C放在B里面，B在A里面，它会给出错误

注意：youtube com.example.fragments.VideoFragment是YouTubePlayerSupportFragment

基于此，滚动YouTubePlayerView所在的页面时出错。当YouTubePlayerView不可见时，视频会因此错误而停止

---

除此之外，任何YouTube播放器（包括YouTube Android播放器）都不受支持。当检测到覆盖时，播放停止，日志中包含有助于调试问题的信息。

我在布局中找不到任何覆盖/填充/边距。
