Android YouTubePlayerApi：YouTubePlayer继续加载

Question

我在我的应用中使用了YouTubePlayerAPI和YouTubePlayerSupportFragment。最近，我发现当从辅助页面支持时，YouTubePlayer会继续在第一页上加载。但我无法找出导致它的原因。我一直在寻找信息，但我找不到任何有用的信息。

我的测试方法：
单击TextView以启动辅助页面。回去，问题出现了。

这是我的代码：

public class FragmentDemoActivity extends Activity implements YouTubePlayer.OnInitializedListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.fragments_demo);

        TextView tvDes = (TextView) findViewById(R.id.tv_start_another);
        tvDes.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                startActivity(new Intent(v.getContext(), FragmentDemoActivity.class));
            }
        });

        YouTubePlayerFragmentWrap youTubePlayerFragment =
                (YouTubePlayerFragmentWrap) getFragmentManager().findFragmentById(R.id.youtube_fragment);
        youTubePlayerFragment.initialize(DeveloperKey.DEVELOPER_KEY, this);
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {
            player.cueVideo("nCgQDjiotG0");
        }
    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

    }
}
