move @produces("application/json; charset-utf-8") , @consumes("application/json; charset-utf-8") annotations class level or put both annotations in both methods. error occurs because resteasy default tries parse response of insertpost application/octet-stream , not have provider it.
also, should consider using client library in android project retrofit. make code cleaner.
