Spaces in String value entered in Firebase DB giving unterminated String error android

Question

I have been manually entering data's into Firebase DB and if the string i entered contains spaces, i am getting JsonExceptionorg.json.JSONException: Unterminated object at character

After searching through some Stackoverflow questions, i also added String.valueOf(obj.getString("key")); to my coding. But it doesn't work for me.

How to add String with spaces in value field in Firebase. Any suggestions would greatly help my learning.

My Firebase Db

My code

   rootRef.addValueEventListener(new com.firebase.client.ValueEventListener() {
            @Override
            public void onDataChange(com.firebase.client.DataSnapshot dataSnapshot) {

               String Jsondatas=String.valueOf(dataSnapshot.getValue());

                try {
                    JSONObject jsonobj=new JSONObject(Jsondatas);
                        JSONArray gkArray = jsonobj.getJSONArray("GK");
                        for(int i=0;i<gkArray.length();i++){
                            JSONObject obj_gk = gkArray.getJSONObject(i);
                            String quest = String.valueOf(obj_gk.getString("Question1"));
                            System.out.println("Questiofrom fb"+quest);
                            String opt_one = String.valueOf(obj_gk.getString("option1"));
                            String opt_two = String.valueOf(obj_gk.getString("option2"));
                            String opt_three = String.valueOf(obj_gk.getString("option3"));
                            String opt_four = String.valueOf(obj_gk.getString("option4"));
                            String ans= String.valueOf(obj_gk.getString("answer"));

                            question.add(quest);
                            Option1.add(opt_one);
                            Option2.add(opt_two);
                            Option3.add(opt_three);
                            Option4.add(opt_four);
                            CorrectAns.add(ans);

You are entering values directly in the console. Right? then it should be like this:- `key: "Value1 Value2"` — Akshay Nandwana, Jul 29 '17 at 03:17
I am attaching my firebase screenshot with the question. At question key, value will be entered with spaces. Can you please take a look at it @anandwana — BraveYard, Jul 29 '17 at 03:20
As we are working with the firebase, we don't require JSONObject to work. Writing the code below using which you can access your database. — Akshay Nandwana, Jul 29 '17 at 03:41

I did Simply like,

In Firebase,

What-is-your-name(Replaced spaces with "-")

And after parsing json,

value.replaceAll("-"," ");

    databaseReference = FirebaseDatabase.getInstance().getReference().child("GK");
     databaseReference.addValueEventListener(new ValueEventListener() {
                    @Override
                    public void onDataChange(DataSnapshot dataSnapshot) {  
              your_text_view.setText(dataSnapshot.child("Question1").getValue().toString());
                     ...
                    }

                    @Override
                    public void onCancelled(DatabaseError databaseError) {

                    }
                });

If you want a list, use FirebaseRecyclerView to get the list of all question and their options.
