android-Youtube api 400错误请求

YouTube Api给出了以下错误，尽管我在查询中提供了“snippet”，它在调试版本中运行良好，而在签名的Apk版本中不工作

{
   "errors" : [ {
   "domain" : "global",
   "reason" : "required",
   "message" : "Required parameter: part",
   "locationType" : "parameter",
   "location" : "part"
   } ],
   "code" : 400,
   "message" : "Required parameter: part"
}

这是我的查询代码： query=youTube.playlists（）.list（“片段”）

按如下方式更改proguard规则：
