Problème compréhension log

Version imprimable

Bonjour,

Je veux faire un tableau dynamique avec des données récupérées d'un script php via une base de données oracle. J'utilise pour cela Json.

Or quand je veux mettre les résultats de cette requete dans mon .java le log m'indique qu'il faut absolument une listView.

Je vous communique mes codes.
