{ registration_id: '',   time_to_live: 60,   'data.type': 'newprocess',   'data.sessionid': 'fd1eceb1-e065-4d9e-9bda-50aecaf89b68',   'data.questions':     [ { question: 'q', answers: ['a', 'b', 'c'], correctanswer: 1 },      { question: 'k', answers: ['a', 'b', 'c'], correctanswer: 1 } ],   'data.users': [] }

solved. article helped , used json.stringfiy in server.

this basic example using jsonobject:

@override public void onmessagereceived(string from, bundle data) {      string myjsonstring = data.getstring("myjson");      jsonobject myjson = new jsonobject(myjsonstring);      int registration_id = myjson.optint("registration_id ");     string time_to_live = myjson.optstring("time_to_live"); }
