不幸的是，youtube播放器已停止工作
我已将api jar文件放在libs文件夹中。当我运行此程序时，我得到很遗憾，youtube播放器已停止工作。
任何人都可以帮助我吗？
我还想知道一件事： 我在java文件中使用了以下语句。它在DEVELOPER_KEY上显示redmark（实际上这是一个存储api密钥的变量）， youTubeView.initialize（Config.DEVELOPER_KEY，this）; 这就是我使用以下声明的原因： youTubeView.initialize（Developer_Key开发，这一点）;
因为这个有什么问题
这是我的activity.java
package com.example.XXX.XXX;

public class YoutubeActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {
public static final String DEVELOPER_KEY = "<Censored>";
public static final String YOUTUBE_VIDEO_CODE = "uOpVvokKnu0";
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(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(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(DEVELOPER_KEY,this);
}
}
private YouTubePlayer.Provider getYouTubePlayerProvider() {
return (YouTubePlayerView) findViewById(R.id.youtube_view);
}
}

由于以下代码，我在设计视图中遇到了一些错误。我会附上那个。

我已经按照以下链接在Android应用中播放youtube。 http://www.androidhive.info/2014/12/how-to-play-youtube-video-in-android-app/我在自己的应用中所做的更改包括： 我在前面添加了以下行Androidmanifest.xml：我在build.gradle中添加了以下行： 编译文件（＆＃39; libs / YouTubeAndroidPlayerApi.jar＆＃39;）
我在libs文件夹中添加了这个jar。 我已经在这个问题中保留了我的xml和java文件的代码。我完全遵循了这个教程。
由于xml：
中的代码如下，您是否遇到任何问题？<com.google.android.youtube.player.YouTubePlayerView
android:id="@+id/youtube_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="30dp" />
我在java文件夹中创建了config.java：
config.java的代码为：
public class config {
// Google Console APIs developer key
// Replace this key with your's
public static final String DEVELOPER_KEY = "";
// YouTube video id
public static final String YOUTUBE_VIDEO_CODE = "uOpVvokKnu0"; }
由于我没有20个声誉，我无法聊天。我还有一个帐户，它有20多个声誉。但我无法在那里找到你。
我们差不多了，请帮助我。
你能现在开始聊天吗？我有20多个声誉。我可以聊聊。
还请找到现在的logcat：

正如你所说，我没有在右键菜单中找到添加为库选项。而且我还没有通过工作室添加jar文件。我已经打开了Androidstudioprojects（存在于C中），我选择了我的项目，因为我打开了lib并复制了jar文件。它在我的项目中显示了libs下的jar文件。我不认为这是添加jar的错误方法，是吗？
1 个答案:
答案 0 :(得分：0)
我已经测试了你的代码，当问题是互联网许可时，我觉得自己很傻。 将其添加到AndroidManifest.xml：
<uses-permission android:name="android.permission.INTERNET"/>
确保您拥有有效的API密钥，因为YoutubePlayer API文档说明了这一点。
如果未设置开发人员密钥，则示例将抛出java.lang.NullPointerException并在您尝试运行时关闭。
修改
要修复布局渲染问题，请使用工具：context as
<AnyRootLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".YouTubeActivit" <!-- Your activity name here -->
>
<!-- Your child elements here -->
</AnyRootElement>
将jar文件添加到libs文件夹中并右键单击该jar文件，然后单击“添加为库”，在android studio中添加jar文件的更多信息here
