cordova媒体插件停止在Android 6上工作。

Question

我在Google上有一个应用程序，它可以从一个用最新的cordova (5.4)构建的电台播放音乐，我正在使用一些基本的插件，例如：

• 设备插件
• 人行横道webview插件
• 对话框插件
• ..。
• 文件插件
• 媒体插件

在Android6.0上，流运行良好，但是最近当我在Android6.0上升级我的5.0+时，流停止了。我将媒体和文件插件更新为最新版本(分别为2.0.0和4.0.0 )，正如cordova在他们的博客中所述，这些版本支持Android 6上的新权限检查，但流仍然无法工作。日志给了我以下内容：

IPADDRESS:端口是一个真正的http://ipaddress:port URL流，运行良好。

我现在与权限有关，但仍然找不到确切的内容。在app-info和新权限菜单上，我看到应用程序使用麦克风、电话和存储权限，这些都是启用的。我搜了很多遍也找不到类似的东西。

任何帮助都是非常感谢的。

Answer 1

在官方回购中查到了吉图布，发现了这

试用了一个新的示例应用程序，并在我的Android6.0设备上工作得很好。这个解决方案与luckakashi的建议非常接近，并附加了一些评论。

Answer 2

我发现了问题，只需在AudioPlayer.java上评论这一行

public void onPrepared(MediaPlayer player) {
    // Listen for playback completion
    this.player.setOnCompletionListener(this);
    // seek to any location received while not prepared
    //this.seekToPlaying(this.seekOnPrepared);
    // If start playing after prepared
    if (!this.prepareOnly) {
        this.player.start();
        this.setState(STATE.MEDIA_RUNNING);
        this.seekOnPrepared = 0; //reset only when played
    } else {
        this.setState(STATE.MEDIA_STARTING);
    }
    // Save off duration
    this.duration = getDurationInSeconds();
    // reset prepare only flag
    this.prepareOnly = true;

    // Send status notification to JavaScript
    sendStatusChange(MEDIA_DURATION, null, this.duration);
}

好像人行横道出了什么问题，你有没有试过，如果你删除了人行横道插件？你的Android6.0设备是64位吗？
