Code to parse JSON using GSON

JsonParser.kt

// Create a Gson object
val gson = Gson()

// Get the json stream from quiz_json raw file
val jsonStream = InputStreamReader(resources.openRawResource(R.raw.quiz_json))

// Create a buffered reader
val bufferedReader = BufferedReader(jsonStream)

// Call the fromJson method to get the parsed results
val questions: List<Question> = gson.fromJson(bufferedReader, Array<Question>::class.java).toList()

// We can iterate on the returned questions
questions.forEach {
  Log.d("JsonParser", it.question)
  Log.d("JsonParser", it.answer)
}
