400 Bad Request on release version apk

Question

I am working on an application which uses youtube data api for fetching data from my channel. I had done all the setup like keys and api on google console for youtube and app is working fine in debug phase. But when I generate my apk for release phase my application did not working as expected. For the call for youtube data api for data it gives following error.

com.google.a.a.b.a.b: 400 Bad Request

   "reason": "required",
  "message": "Required parameter: part",

 }
],
"code": 400,

}

My code for extracting data is here :

mYouTubeDataApi = new YouTube.Builder(AndroidHttp.newCompatibleTransport(),new  GsonFactory(),null)
    .setApplicationName("app").build();

searchlistResponse = mYouTubeDataApi.search().list("snippet")
    .setChannelId(Constants.CHANNELID).setFields("items(id/videoId),nextPageToken")
    .setMaxResults((long) results)
    .setKey(Constants.YOUTUBEDEVELOPERKEY)
    .setType("video").setOrder("date").execute();

Error message saying that some part parameter is missing but this working perfectly in debug phase and even in browser but not in release phase. What am I missing or doing wrong. Or is it caused due to gradle while shrinking resources or something while generating relase apk. Please help me to find the bug.

I think it's a problem with Proguard. To fix it, add this:

-keep class com.google.api.** { *; }

And the problem should be solved.
