How to decode JSON values in my Android Aplication?

Question

Hello guys I\'m trying to decode a JSON value into my Android Application, But I\'m not really sure What Am I doing wrong in my code...

This is my PHP file:

Answer 1

I will try to answer :-

1. As per your code you have this String ["1","Admin","123","Adm","messages","0"] which is clearly a jsonarray but you are parsing as jsonobject in android.

2. as @Boban said you must not run network operations on main thread so avoid dat.

Now taking the response as what i mentioned in 1 here is how you will do :-

JSONArray jArray=new JSONArray(json_str)
String id=jArray.getString(0);
String admin=jArray.getString(1);
.
.
.

Hope it helps ... and if i m wrong please correct me :)

thx

Answer 2

There are a couple of options for you available to achieve this.

Personally i like to use the built in JSON parser in Android

JSONObject jObject = new JSONObject(result);

You can also use Google's json parse library https://google-gson.googlecode.com/svn/trunk/gson/docs/javadocs/com/google/gson/Gson.html

Also see this link for details on how to actually parse JSON and get Strings that you can use in your program. How to parse JSON in Android

Answer 3

try

 <?php   echo json_encode($mostra_player, JSON_FORCE_OBJECT); ?> 

which forces to be an object.

Then you can access it in java/android with

JSONObject obj = (JSONObject) new JSONTokener(json_string_output).nextValue();
String yourdata= obj.getString("yourdata");

If you want an Array try

<?php echo json_encode(array("data" => $mostra_player)); ?>

        JSONObject json = new JSONObject(responsedata);
        JSONArray jArray = json.getJSONArray("posts");
        for (int i = 0; i < jArray.length(); i++) {
            JSONObject e = jArray.getJSONObject(i);
            JSONObject jObject = new JSONObject(e.getString("data"));

            Log.d("yourdata", jObject.getString("yourdata"));
            Log.d("moredata", jObject.getString("moredata"));
        }
