Android：如何在活动中正确初始化 YouTube 播放器？

Question

我正在尝试在活动中启动 YouTube 播放器。但是，我不时会收到此异常：

Fatal Exception: java.lang.IllegalStateException YouTubeServiceEntity not initialized

这是我尝试在我的活动中初始化 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，这个问题并不持久。它只是不时发生，我不知道为什么。你能告诉我这可能是什么原因造成的吗？

这里也是logcat：

我现在在我的应用程序中也面临这个错误。当用户在未正确初始化的情况下退出包含活动的 Youtube 播放器片段时，就会出现问题。它非常随机，不容易复制。

我只是使用 try-catch 来避免它，幸运的是，它还没有被复制。

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

再说一遍，这可能不是可靠的解决方案。

一种解决方案可能是检查OnBackPressed() youtube 播放器是否已初始化。

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; 
}

尝试使用猴子更频繁地复制它。

adb shell monkey -p com.packagename -v 500

我也遇到了这个错误，我通过创建一个扩展 YouTubePlayerSupportFragment 的自定义类来解决它，也许我的代码对你有帮助，这对我来说很好。

我像这样初始化我的 youtube 播放器：

private String currentVideoID = "<your video id>";
private YouTubePlayer activePlayer;

private void init() {

    initialize(ConstantsRepository.GOOGLE_API_SERVER_KEY, new YouTubePlayer.OnInitializedListener() {

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
            // youtube is not installed
        }

        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
            activePlayer = player;
            activePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
            if (!wasRestored) {
                activePlayer.loadVideo(getArguments().getString("url"), 0);
            }
        }
    });
}

在您的活动中，在 layout.xml 中提供一个 youtube 片段，并在 onCreate 中进行以下替换：

 YTPlayerFragment myFragment = YTPlayerFragment.newInstance("oVkK3X9zMyI");
        getFragmentManager().beginTransaction().replace(R.id.youtube_container, myFragment).commit();

经过一番挖掘，我发现了我的问题。问题出在我使用的 youtube 库上。它已经过时了，HERE 一切都很好:)

Answer 4

试试这个方法

这里的 Activity 是从 YouTubeBaseActivity 扩展而来的，它将出现在 YouTubeAndroidPlayerApi.jar 中。此活动还包含一些初始化侦听器方法来了解 youtube 播放器的状态。和follow this example for more help

import android.content.Intent;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Toast;

import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.PlayerStyle;
import com.google.android.youtube.player.YouTubePlayerView;

public class MainActivity extends YouTubeBaseActivity implements
        YouTubePlayer.OnInitializedListener {

    private static final int RECOVERY_DIALOG_REQUEST = 1;

    // YouTube player view
    private YouTubePlayerView youTubeView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.activity_main);

        youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

        // Initializing video player with developer key
        youTubeView.initialize(Config.DEVELOPER_KEY, this);

    }

    @Override
    public void onInitializationFailure(YouTubePlayer.Provider provider,
            YouTubeInitializationResult errorReason) {
        if (errorReason.isUserRecoverableError()) {
            errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
        } else {
            String errorMessage = String.format(
                    getString(R.string.error_player), errorReason.toString());
            Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider,
            YouTubePlayer player, boolean wasRestored) {
        if (!wasRestored) {

            // loadVideo() will auto play video
            // Use cueVideo() method, if you don't want to play it automatically
            player.loadVideo(Config.YOUTUBE_VIDEO_CODE);

            // Hiding player controls
            player.setPlayerStyle(PlayerStyle.CHROMELESS);
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_DIALOG_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(Config.DEVELOPER_KEY, this);
        }
    }

    private YouTubePlayer.Provider getYouTubePlayerProvider() {
        return (YouTubePlayerView) findViewById(R.id.youtube_view);
    }

}

这对我有用

请从here下载.Jar

在你的 bins 文件夹中添加 YouTubeAndroidPlayerApi.jar。

及以下用于播放 Youtube 视频的活动

if (url.contains(Constants.YOUTUBE_URL)) {
            final String key[] = url.split("v=");
            if (key.length > 1) {
                final Intent intent = new Intent(getActivity(), YouTubeActivity.class);
                intent.putExtra(Constants.KEY_VIDEO_KEY, key[1]);
                startActivity(intent);
                getActivity().overridePendingTransition(R.anim.anim_zoom_in, R.anim.anim_zoom_out);
            } else {
                Utils.showSnackbarNonSticky(mRecyclerView, "URL is not valid", true, mContext);
            }
        }

下面的活动是播放视频

public class YouTubeActivity extends YouTubeBaseActivity 
    implements YouTubePlayer.OnInitializedListener, View.OnClickListener {

private static final int RECOVERY_REQUEST = 1;
private YouTubePlayerView youTubeView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_youtube);
    initView();
}

//this method is for the initialization of the view component
private void initView() {
    final LinearLayout llParent = (LinearLayout) findViewById(R.id.activity_you_tube_parent_layout);
    youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
    youTubeView.initialize(Constants.YOUTUBE_DEVELOPER_KEY, this);
    final TextView tvClose = (TextView) findViewById(R.id.activity_you_tube_tv_close);
    tvClose.setOnClickListener(this);

    llParent.setOnTouchListener(new OnSwipeTouchListener(this) {
        public void onSwipeTop() {
        }

        public void onSwipeRight() {
        }

        public void onSwipeLeft() {
        }

        public void onSwipeBottom() {
            finish();
            overridePendingTransition(R.anim.anim_zoom_in, R.anim.anim_zoom_out);
        }

    });

    final WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    final Window window = this.getWindow();
    lp.copyFrom(window.getAttributes());
    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
    lp.height = WindowManager.LayoutParams.MATCH_PARENT;
    window.setAttributes(lp);
}

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
    if (!wasRestored) {
        player.loadVideo(getIntent().getStringExtra(Constants.KEY_VIDEO_KEY));
        player.setShowFullscreenButton(false);
    }
}

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
    if (errorReason.isUserRecoverableError()) {
        errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
    }

}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == RECOVERY_REQUEST) {
         getYouTubePlayerProvider().initialize(Constants.YOUTUBE_DEVELOPER_KEY, this);
    }
}

protected YouTubePlayer.Provider getYouTubePlayerProvider() {
    return youTubeView;
}

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.activity_you_tube_tv_close:
            finish();
            this.overridePendingTransition(R.anim.anim_zoom_in, R.anim.anim_zoom_out);
            break;
    }
}

@Override
public void onBackPressed() {
    final boolean backEnable = false;
    if (backEnable) {
        super.onBackPressed();
    }
}

}
