Android: Reading JSON files fails

I've tried many ways but they all keep saying the file doesn't exist, but it does. It's located in the java folder but when it tries to read it it fails. I've taken out the JSON codes, and storing it in to Cloudboost works when I hard code it, but i can't do it for over 1000 questions and answers...

This is the updated code:

public String loadJSON() {
    String json = null;
    try {
        InputStream is = this.getAssets().open("QA.json");
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();
        json = new String(buffer, "UTF-8");
    } catch (IOException ex) {
        ex.printStackTrace();
        return null;
    }
    return json;
}

public void addToTable() throws CloudException, FileNotFoundException, IOException, ParseException {
    CloudObject table = new CloudObject("QuestionsAndAnswers");

    ArrayList<String> question = new ArrayList<String>();
    ArrayList<String> answer = new ArrayList<String>();
    ArrayList<Double> earnings = new ArrayList<Double>();

    JSONParser jsonParser = new JSONParser();
    Object obj = jsonParser.parse( new FileReader( loadJSON() ) );
    JSONArray jsonArray = (JSONArray) obj;

    for (int i = 0 ; i < jsonArray.size() ; i++) {
        JSONObject jsonObject = (JSONObject) jsonArray.get(i);
        question.add( (String) jsonObject.get("Question") );
        answer.add( (String) jsonObject.get("Answer") );
        if ( jsonObject.get("Earnings") != null ) {
            earnings.add( (Double) jsonObject.get("Earnings") );
        }
    }

    question.add("Hello" + "?");
    answer.add("Hi");
    earnings.add(100.00);

    question.add("What's up" + "?");
    answer.add("Nothing.");
    earnings.add(50.00);

    for (int i = 0 ; i < question.size() ; i++) {
        table.set("question", question.get(i));
        table.set("answer", answer.get(i));
        table.set("earnings", earnings.get(i));

        table.save(new CloudObjectCallback() {
            @Override
            public void done(CloudObject x, CloudException e) {
                if (e != null) {
                    // Error
                    Log.i("TABLE ERROR:", e.getMessage());
                }
                if (x != null) {
                    // CloudObject
                }
            }
        });
    }
}

This is the error I use to get:

Solution

  • It's directly under the app/java folder

    That is on your development machine. That is not on the Android device.

    If you want to ship JSON with your Android app, put it in assets/. Then, use AssetManager to get an InputStream on the asset to pass to your desired JSON parser.
