Your Map values are JsonElements. Whenever you print a JsonElement (e.g. using a debugger) its toString() method will be called - and since a JsonElement has many implementing classes the default toString implementation wraps the value in quotes to ensure correct JSON. To get the value as a normal, unwrapped String, simply call getAsString():

JsonElement elem;
// ...
String value = elem.getAsString();

With your example:

Map attributes = new HashMap();
Set> entrySet = jsonObject.entrySet();
for(Map.Entry entry : entrySet){
  attributes.put(entry.getKey(), jsonObject.get(entry.getKey()).getAsString());
}

Note there are many other methods you can call on a JsonElement to produce other types.
