Problème connexion BDD MySQL
Bonjour,
Je travaille sur un application qui dois récupérer des valeurs dans un BDD MySQL, pour l'instant en local. Et faire afficher les valeurs dans une ListView. Donc j'ai un Adapter Personnaliser car je dois envoyer deux types de données.
Le problème est qu'il m'est impossible de lancer mon application, ça vient des fonctions RecupDate() et RecupInfo().
Voila mon MainActivity.java
Code:

Quelqu'un saurait-il d'où peut venir le problème ?
Merci d'avance pour votre aide.
