Answer 1

You can use this method in order to parse generic json string to map

    public Map getMapFromJson(String jsonString) {
    Map map = new HashMap<>();
    try {
        JSONObject object = new JSONObject(jsonString);
        Iterator iterator = object.keys();
        while (iterator.hasNext()) {
            String key = (String) iterator.next();
            if(!key.isEmpty() && !object.getString(key).isEmpty()){
                map.put(key, object.getString(key));
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
    return map;
}
