推荐答案

的老年主题。

据接缝，给定链接到Android音乐播放器，应用程序无法使用了。但是，在GitHub镜像可以发现这里。

It seams, that the given link to the Android Music Player-App isn't available anymore. But, a Mirror on GitHub can be found here.

如果我们现在采取的<一看href=\"https://github.com/android/platform_packages_apps_music/blob/master/src/com/android/music/MusicUtils.java\"相对=nofollow>MusicUtils'级，我们看到相册ID来自被称为对象'sService'，这是一个IMediaPlaybackService'-实例。这是一个AIDL-文件，让我们来看看在<一实施href=\"https://github.com/android/platform_packages_apps_music/blob/master/src/com/android/music/MediaPlaybackService.java\"相对=nofollow>MediaPlaybackService'级。

If we now take a look on the 'MusicUtils'-class, we see that the Album ID comes from an Object called 'sService', which is a 'IMediaPlaybackService'-Instance. This is an AIDL-File, so we look at the implementation in the 'MediaPlaybackService'-Class.

原来这就是'getAlbumID（） - 方法，我们发现：

So this is the 'getAlbumID()'-method we find:

public long getAlbumId() {
    synchronized (this) {
        if (mCursor == null) {
            return -1;
        }
        return mCursor.getLong(mCursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID));
    }
}

MediaStore是一个标准的Andr​​oid内容提供商，这是记载
