Bonjour, je travail sur un projet scolaire d'une application Android qui permet de visualiser une ListView de tout mes logements. J'ai une méthode InsertLogement() qui ajoute quelques logements et cela fonctionne, en revanche lorsque j'essais d'ajouter des logements depuis un "formulaire" (Edit Text) et y insérer les valeurs en utilisant la même fonction l'application plante. Je me retrouve bloquer avec ce problème et tout ce que j'essais ne fonctionne pas.
Avez-vous des idées vers lesquels je pourrais m'orienter ?
Merci d'avance !

à savoir que ma listview et mon formulaire sont placer dans une TabHost. Tab1 = listview et Tab2 = formulaire
LogementDbAdapter.java
