J'ai suivi un didacticiel pour développer un formulaire d'inscription d'utilisateur. En suivant ce code, je crée un autre client d'appel de table et crée d'autres classes pertinentes. Mais une fois que je clique sur le bouton Enregistrer, mon application a cessé de fonctionner. J'essaye beaucoup de corriger cette erreur, mais ça ne marche pas. S'il vous plaît, si quelqu'un pouvait m'aider à trouver ce problème, j'apprécie vraiment votre aide. MerciProblème lors de l'enregistrement des données dans la base de données Android Sqlite avec plusieurs tables
Il s'agit du fichier activity_client.xml.

Vous devez avoir un regard sur le message d'erreur exacte pour que nous puissions vous aider. Sur Android Studio, il est généralement disponible sous l'onglet Débogage/Exécution en bas, ou sur la vue Logcat également en bas de la fenêtre AS. Habituellement, les premières lignes en rouge seront les plus utiles, suivies des paires de noms de fichiers + numéros de ligne que vous pouvez utiliser pour trouver où se trouve le problème dans votre code. – Fabio
