在我们的项目中，gdata只有在设备语言设置为土耳其语时才无法加载YouTube播放列表。以下是一些日志：

看起来 youtube 解析器失败了。这个问题是相关的：https://code.google.com/p/gdata-java-client/issues/detail?id=126，我已经下载了最新的gdata库，但没有任何帮助。此外，我还按照INSTALL-src文件中的描述重新构建了gdata，但是新生成的jar文件的大小（~每个>2kB）相对于原始jar不同，尽管我没有更改代码。我在构建过程中有这样的警告：
[javac] m:devgdata-libsgdatajavabuild-srccore.xml:155: warning: 'inclu

or repeatable builds

当我尝试在我的项目中替换这些jar时，我收到验证错误：
Could not find class 'com.google.gdata.data.youtube.VideoFeed', referenced from method com.my.package

感谢任何帮助。谢谢，迈克。
我建议您尽快迁移到Data API v3。下面是一个包含 Data API v3 的 Android 项目示例。
