Bonjour, J'arrive pas faire passer les données de mon Json vers mon code Java (Développement Android), je ne sais pas si c'est mon Json qui n'est pas normal ou mon code Java.

Code Java

String url="http://XXXXXXX/YYYY/KKK.php?code=AAAA";

        HttpHandler hh = new HttpHandler();
        String jsonStr = hh.makeServiceCall(url);

        try {
            JSONObject usrObj = new JSONObject(jsonStr);
               
                JSONObject c = usrObj.getJSONObject("client");
                String username = c.getString("password");
                String valide = c.getString("valide");
                String expiration = c.getString("expiration");
            
                Integer heure = c.getInt("heure");
                SQLiteDatabase mydatabase = openOrCreateDatabase("XXXX",MODE_PRIVATE,null);
                mydatabase.execSQL("CREATE TABLE IF NOT EXISTS Client(username VARCHAR,valide VARCHAR,expiration VARCHAR,heure VARCHAR);");
                mydatabase.execSQL("INSERT INTO Client VALUES('"+username+"','"+valide+"','"+expiration+"','"+heure+"');");

        } catch (final Exception e) {

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(getApplicationContext(),
                            "Json parsing error: " + e.getMessage(),
                            Toast.LENGTH_LONG).show();
                }
            });

Code Json

{"client":{"password":"xxxx","valide":"valide","expiration":"2018-12-04 17:14:35","heure":"2887200"}}

Merci
