我已将YouTubePlayerView库集成到我们的应用程序中，并且其工作正常但是每当我最小化应用程序时它会崩溃，或者您可以说应用程序在后台崩溃时会崩溃。

以下是崩溃日志：

这是我的清单：

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

您可以参考此SO post，提出一些可能有用的解决方法：

  • 在YouTubePlayer和onSavedInstanceState发布onStop。
@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();
}
  • 如果它不起作用，只需在onPause而不是onSaveInstanceState和onStop中添加相同的行，并在{{1}中初始化YouTubePlayerFragment而不是onResume，所以每次活动处于前台时它都可用，并在应用程序进入后台时释放。

我认为由于配置更改而导致应用程序在重新启动时崩溃

您可以禁用方向更改的自动活动娱乐，并自行处理。

为此，请添加

android:configChanges="orientation|screenLayout|screenSize"

了解更多信息runtime-changes

或在您的活动中添加此代码

@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();
}
