If I build a query like String query = "{feed(count:50,start:0,id:\"5a831642ce4c05360b8831cb\"){name id}}, and pass it to the client like mOkGraphql.query(query).enque(...), it does not work and results in malformed JSON in server.
If I construct the query as String query = "{feed(count:50,start:0,id:\\\"5a831642ce4c05360b8831cb\\\"){name id}}, then it works. I think the library should take care of escaping the string.
