android - 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，我得到不幸的是，youtube 播放器已停止工作。

有人可以帮助我吗？

我还想知道一件事:我在java文件中使用了下面的语句。它在DEVELOPER_KEY处显示红色标记(实际上这是一个存储api key 的变量)， youTubeView.initialize(Config.DEVELOPER_KEY, this);这就是为什么我使用以下声明:youTubeView.initialize(DEVELOPER_KEY,this);

因此有什么问题吗

这是我的activity.java

    package com.example.XXX.XXX;

    import android.content.Intent;
    import android.graphics.Bitmap;
    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 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);
        }

    }

这是我的 XML 代码

由于下面的代码，我在设计 View 上遇到了一些错误。我会附上它。

<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" />

That is error I'm getting on XML file

this is the continuation for this error

我已按照以下链接在 Android 应用程序中播放 YouTube。 http://www.androidhive.info/2014/12/how-to-play-youtube-video-in-android-app/我在应用程序中所做的更改是:我在 Androidmanifest.xml 下添加了这一行，如前所述:我在 build.gradle 中添加了以下行:编译文件('libs/YouTubeAndroidPlayerApi.jar')

我已将此 jar 添加到 libs 文件夹中。我已经在这个问题中保留了我的xml和java文件的代码。我完全按照该教程进行操作。

由于 xml 中的以下代码，您没有遇到任何问题吗:

<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";  }

Screenshot of where I have added jar file

由于我没有 20 个声望，所以无法聊天。我还有一个帐户，它有超过 20 个声誉。但我在那里找不到你。

我们快到了，请帮助我。

现在可以启用聊天功能吗？我有超过20个声誉。我可以聊天。

还请找到当前的 logcat:

正如您所说，我在右键菜单中没有找到“添加为库”选项。而且我也不是通过工作室添加了 jar 文件。我已经打开了 Androidstudioprojects(存在于 C 中)，并且选择了我的项目，因为我打开了库并复制了 jar 文件。它显示了我项目中 libs 下的 jar 文件。我不认为这是添加 jar 的错误方法，是吗？ right click menu

最佳答案

我已经测试了你的代码，当问题是互联网许可时，我感觉自己像个傻瓜。将其添加到您的 AndroidManifest.xml 中:

<uses-permission  android:name="android.permission.INTERNET"/>

根据 YoutubePlayer API 文档所述，确保您拥有有效的 API key 。

If you do not set the developer key, the samples will throw a java.lang.NullPointerException and close when you attempt to run them.

编辑:

要修复布局渲染问题，请使用tools: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，然后右键单击该 jar 文件，然后单击“添加为库”有关在 android studio 中添加 jar 文件的更多信息 here

我的 Build.gradle(用于应用程序模块):

apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.mypackage.youtubedemo"
    minSdkVersion 9
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

    dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile files('libs/YouTubeAndroidPlayerApi.jar')
}

关于android - 不幸的是，youtube 播放器已停止工作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30001150/
