1 - Presentation of the functionalities

Up-to-date is an app that permits you to stay 'Up to date'. Everyday you will have a quizz of 5 questions where an image will be presented to you and you will have to guess the title of it.

1 - 1) Menu

Type a name in order to start the quizz !

1 - 2) Question 1/5 (Question view)

1 - 3) Question 1/5 (Alert Correct Answer View)

I have an image and four news titles. I have to guess which title correspond to the image. If I'm right I earn a point, if i'm not I don't earn any point.

I chose the correct answer. I earned a point. I have the opportunity to read the full article. I'm not going to miss it.

1 - 4) Question 1/5 (Full article View)

1 - 5) Question 2/5 (Question view)

I can read the full article and when I will touch the 'return button' of my smartphone it will directly lead me to the next question.

Let's assume now that I mess up on purpose and that I choose a wrong answer.

1 - 6) Question 2/5 (Alert Wrong Answer View)

1 - 7) Question 3/5 (Question View)

Well I was wrong so I didn't earn any points however I still have the right to read the full article. Let's say that i am very stubborn and choose not to read the full article.

You saw, it directly led me to the next question ! Now this one is way too obvious I have to get that one right !

1 - 8) Question 3/5 (Alert Right Answer View)

1 - 8) Question 3/5 (Full article View)

I knew it ! But still I want more information on this subject !

Ohh very interesting ! Now I think you pretty much understood how the app works so let's skip the two next answers !

1 - 9) Final score view

Wow guess i'm pretty 'up-to-date'. The see you tommorow button will lead you to the menu. Tomorrow the question will be automatically changed and will be different.

2 - More details about the Api

the Api that I used for this project is called news.api https://newsapi.org

this is the url that we used (Api key has been removed :) 

String url = "https://newsapi.org/v2/top-headlines?country=fr&apiKey=";

So you can see that we are calling the top headlines in France.

The Api will respond with a JSON file which will be looking like that :

{
"status": "ok",
"totalResults": 34,
-"articles": [
-{
-"source": {
"id": "lequipe",
"name": "L'equipe"
},

This is the code that takes out the data from the JSON file and transforms it into a java object :

					mQueue = Volley.newRequestQueue(this);

        String url = "https://newsapi.org/v2/top-headlines?country=fr&apiKey=5e5b4f88a60f488aa44b243036dfbad7";

        JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, url, null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.i("Json request", String.valueOf(response));
                        try {
                            JSONArray jsonArray = response.getJSONArray("articles");

                            for (int i = 0; i < nbArticles; i++) {
                                JSONObject articleJSON = jsonArray.getJSONObject(i);

                                String titre = articleJSON.getString("title");
                                String auteur = articleJSON.getString("author");
                                String description = articleJSON.getString("description");
                                String url = articleJSON.getString("url");
                                String img = articleJSON.getString("urlToImage");
                                String publishedAt = articleJSON.getString("publishedAt");
                                String content = articleJSON.getString("content");
//

                                Article article = new Article(i,titre,auteur,description,url,img,publishedAt,content);
                                articles.add(article);
                            }

                            LoadQuestion(indiceQuestion);


                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                error.printStackTrace();
            }
        });

        mQueue.add(request);
