php - 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:

<?php 

    ... 
    echo json_encode($mostrar_player);
    ...

?>

Which Will return me something like this: ["1","Admin","123","Adm","messages","0"]

in my Android Application I need to put that value into an Array there I can select values separeted, but how?

this is my Android Code code:

        EditText campoLogin = (EditText)findViewById(R.id.campo_de_login);
        EditText campoSenha = (EditText)findViewById(R.id.campo_de_senha);

        toast("Conectando...");
        Conectar Conn = new Conectar("http://website/chat/login.php?login=" + campoLogin.getText() + "&senha=" + campoSenha.getText() );
        Log.i("-RESPOSTA-",Conn.response); 
        // HERE IN Conn.response I have my response ["1","Admin","Admin","Admin","affs","0"]

        String json_str = Conn.response;
        JSONObject json = new JSONObject(json_str);
        JSONArray jArray = json.getJSONArray("msg");

        //Log.i("JSON",json_data.getString("msg"));

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
