android - 移动到 youtube 应用程序时，Youtube SDK 因 DeadObjectException 而崩溃

Question

我的应用使用 Youtube Android SDK 提供 youtube View 。 显示视频没有问题，但在打开 youtube 应用程序时会因 DeadObjectException 而崩溃。

我的代码如下

//init
FragmentTransaction fragmentTransaction = fm.beginTransaction();

YouTubePlayerSupportFragment fragment = new YouTubePlayerSupportFragment();
fragmentTransaction.replace(R.id.fragmentz, fragment);
fragmentTransaction.commit();

fragment.initialize(Constants.YOUTUBE_DEV_KEY, this);

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, final YouTubePlayer youTubePlayer, boolean wasRestored) {
    if (!wasRestored) {
        this.youTubePlayer = youTubePlayer;
        this.youTubePlayer.setShowFullscreenButton(true);
        try {
            this.youTubePlayer.loadVideo(youtubeLink);
            //other stuff
        } catch (IllegalStateException e) {
            Logger.e(e);
        }
    }
}

当 1) 通过 intent 直接移动到 youtube 应用程序或 2) 通过播放器 View 上的 youtube 图标移动到 youtube 应用程序时，它会崩溃。

崩溃日志如下

请帮我解决这个问题。

我已经在 nexus 5、android 4.4、youtube api 1.0、youtube app 5.3.24 上测试过

Answer 1

在调用 youTubeView.initialize 之后和调用 onInitializationSuccess 之前，当设备正在旋转(或导致 Activity 重新启动的其他系统配置更改)时会发生这种情况。我的理解是，当您此时旋转您的设备时，原始玩家对象将变为死机，并且假设调用 onInitializationSuccess 的线程仍在运行，一旦该线程调用 onInitializationSuccess 它将使用死机玩家对象。

用下面的 try catch 包裹你的播放器将解决问题:

try{
   youtubeplayer.load(0..;
}catch (IllegalStateException ise){
   //do nothing probably device go rotated
   return;
}
