我正在尝试在 Activity 中启动YouTube播放器。但是,我有时会不断收到此异常:

Fatal Exception: java.lang.IllegalStateException YouTubeServiceEntity not initialized

这是我在 Activity 中尝试初始化youtube播放器的方法。 (这是在OnCreate()内部完成的)
 try {
        final YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        youTubeView.initialize("KEY", new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean Boolean) {
                if(ad==null || ad.getVideo_urls() == null)
                    return;

                if (!Boolean)
                {
                    try {
                        if (ad.getVideo_urls() != null && ad.getVideo_urls().length() > 0) {
                            String url = ad.getVideo_urls().getString(0);
                            if (url.contains("youtube")) {
                                String id = ad.getVideo_urls().getString(0).split("embed/")[1];
                                youTubeView.setVisibility(View.VISIBLE);
                                MyYouTubePlayer = youTubePlayer;
                                MyYouTubePlayer.cueVideo(id);
                            }
                        } else {
                            youTubeView.setVisibility(View.GONE);
                            Log.i(Constants.getTag(), "Video not found");
                            //Making sure the MyYouTubePlayer is null and if not is being released
                            if(MyYouTubePlayer != null)
                            {
                                MyYouTubePlayer.release();
                            }
                        }
                    }
                    catch (JSONException e) {
                        youTubePlayer.release();
                        e.printStackTrace();
                    }
                }
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                youTubeView.removeAllViews();
            }
        });

    } catch(Exception e){
        e.printStackTrace();
        Log.e("Youtube", "error initializing youtube");
    }

最奇怪的是,这个问题不是持久的。它只是不时发生,我不知道为什么。你能告诉我是什么原因造成的吗?

这也是logcat:

最佳答案

我现在也正在我的应用程序中遇到此错误。当用户退出包含 Activity 的Youtube播放器 fragment 而未正确初始化时,就会发生问题。它是相当随机的,并且不容易复制。

我只是使用try-catch来避免它,幸运的是,它尚未被复制。

try {
    mYouTubePlayerFragment.initialize(DEVELOPER_KEY, this);
} catch(IllegalStateException w){}

再次,这可能不是确定的解决方案。

一种解决方案是检查OnBackPressed()是否已初始化You-tube播放器。
isInitializationComplete = false

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
    isInitializationComplete = true;
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
                                    YouTubeInitializationResult youTubeInitializationResult) {
    isInitializationComplete = true;
}
 @Override
public void onBackPressed() {
   if(!isInitializationComplete) return;
}

尝试猴子以更频繁地繁殖它。
adb shell monkey -p com.packagename -v 500
