JsonObject jsonObject = new Gson().fromJson(json, JsonObject.class);
JsonArray jsonArray = jsonObject.getAsJsonArray("firstname");

String[] firstNameList= new Gson().fromJson(jsonArray, String[].class);

List<String> allNames= new ArrayList<>();
allNames= Arrays.asList(firstNameList);

for (String name: allNames) {
   Log.d(TAG,name);
}
