当调用新 Intent 上的 startActivity 时，DialogFragment 正在重新启动

Question

在我的 Android 应用程序中，我有一个包含 ListView 的对话框片段。列表视图中项目的 onclick 处理程序调用我的 internalPlayer 方法，该方法调用 VideoView activity 来播放视频。 VideoView activity 在应用程序的其他地方使用，所以我知道它正在工作。

private void internalPlayer(final String channelUrl)
{
    final Intent localIntent = new Intent(getActivity(), InternalVideoActivity.class);
    localIntent.putExtra(EXTRA_VIDEO_URI, Uri.encode(channelUrl, ALLOWED_URI_CHARS).toString());
    localIntent.putExtra(GridViewFragment.CHANNEL_NAME, mCategory.toString() + " Episode ");
    getActivity().startActivity(localIntent);
}

当运行在平板电脑上安装应用程序时，一切正常，视频 activity 开始并播放视频。当我运行设备上的应用程序在 phone 设备上单击 ListView 中的项目时，对话框片段会自行重新启动，并且由于最初传递给它的序列化对象不再存在，因此会抛出 NullPointerException。

这是日志：
