Android 应用程序最小化时YouTubePlayerView的活动崩溃

我已经将YouTubePlayerView库集成到我们的应用程序中，它工作得非常好，但每当我最小化应用程序时，它就会崩溃，或者你可以说，每当应用程序在后台运行时，它就会崩溃

以下是崩溃日志：

这是我的舱单：

<activity android:name=".activities.VideoActivity"
            android:configChanges="orientation|screenLayout|screenSize"/>

我认为您的应用程序在重新启动时由于配置更改而崩溃

您可以禁用方向更改的自动活动重新创建，并自行处理

要做到这一点，请添加

android:configChanges="orientation|screenLayout|screenSize"

更多信息

或者在活动中添加此代码

@Nullable
protected YouTubePlayer mUtPlayer;

@Override
public void onSaveInstanceState(Bundle outState) {
/* release ut when home button pressed. */
if (mUtPlayer != null) {
    mUtPlayer.release();
}
mUtPlayer = null;
super.onSaveInstanceState(outState);
}

@Override
public void onStop() {
/* release ut when go to other fragment or back pressed */
if (mUtPlayer != null) {
    mUtPlayer.release();
}
mUtPlayer = null;
super.onStop();
}

您可以参考这篇文章，其中提出了一些可能有帮助的解决方法：

在onSavedInstanceState和onStop上释放YouTubePlayer。 如果不起作用，只需在onPause中而不是onSaveInstanceState和onStop中添加相同的行，并在onResume中而不是onCreate中初始化YouTubePlayerFragment，这样每次活动在前台时都可用，当应用程序进入后台时释放。 附加参考：

我已经在清单中添加了android:configChanges=orientation | screenLayout | screenSize这段代码，但仍然面临问题。请查收。

@Nullable
protected YouTubePlayer mUtPlayer;

@Override
public void onSaveInstanceState(Bundle outState) {
    /* release ut when home button pressed. */
    if (mUtPlayer != null) {
        mUtPlayer.release();
    }
    mUtPlayer = null;
    super.onSaveInstanceState(outState);
}

@Override
public void onStop() {
    /* release ut when go to other fragment or back pressed */
    if (mUtPlayer != null) {
        mUtPlayer.release();
    }
    mUtPlayer = null;
    super.onStop();
}
