android - Youtube 播放器因在 Android 中提供 java.lang.IllegalStateException : android. os.DeadObjectException 而崩溃

Question

我正在做一个项目。我在 Activity 中使用 YouTubeAndroidPlayerAPI 和 Webview。 当我尝试使用其 ID 运行视频时，它运行了。问题是，但如果视频 ID 为空，那么我不会按照代码中的说明运行或初始化视频，然后它会给我以下 logcat 输出，我的应用程序会崩溃，并给出消息 "Unfortunately You tube已经停止”。任何人都可以帮助我，因为我做了很多搜索但找不到任何解决方案。 我的 Activity 扩展 SherlockYouTubeActivity。 SherlockYouTubeActivity 包含 SherlockActivity 代码，但尽管有 Activty，它还是扩展了 YouTubeBaseActivity。因此，通过这样做，我通过 Multilevel Inheritance 将 SherlockActivity 和 YouTubeBaseActivity 扩展到了我的 Activity。

我的 LogCat 输出 如下:-

Answer 1

上面的代码现在可以正常工作了，造成该异常的所有原因是，一些 VideoId 为空，一些为“”，因此值为“”的 VideoId 对我造成了异常，因为我只是在检查对于空值而不是 VideoId 的“”值。现在问题已经解决了。

如果任何人需要使用 Youtube Android API 代码可以简单地使用上面的代码。即使在 Sherlock Activity 中也能正常工作。

感谢那些尝试和支持我的人的反馈。
