I'm using Google client libraries and trying to make a GET request to Google Play API.

        GoogleCredential credential= new GoogleCredential.Builder().setTransport(netHttpTransport)
                .setJsonFactory(jacksonFactory)
                .setServiceAccountId(CLIENT_ID)
                .setServiceAccountScopes(SCOPE)
                .setServiceAccountPrivateKeyFromP12File(file)
                .build();
                credential.refreshToken();     
        HttpRequestFactory requestFactory =netHttpTransport.createRequestFactory(credential);
        GenericUrl url = new GenericUrl(URI);
        HttpRequest request = requestFactory.buildGetRequest(url);
        HttpResponse response = request.execute();

I get 

 {
  "code" : 401,
  "errors" : [ {
    "domain" : "androidpublisher",
    "message" : "This developer account does not own the application.",
    "reason" : "developerDoesNotOwnApplication"
  } ],
  "message" : "This developer account does not own the application."
}

My app is unpublished, would that cause the problem?
