Bonjour, je suis en train d'essayer de développer une application de service, et j'ai un problème avec la page de connexion/inscription que j'ai crée. Voilà le truc:


quand je clique sur le bouton Meine Daten (mes données pour ceux qui ne parlent pas allemand ) j'arrive bien sur la page MeineDatenActivity, par contre quand je clique sur Verbindung (connexion) ou Anmeldung (inscription) l'appli plante, ça me met un message et puis revient à l'activité principale. Mais quand j'enlève la partie de code correspondant à l'action sur le bouton Anmeldung par exemple, alors là le bouton Verbindung fonctionne (enfin pas tout à fait comme je le voudrais mais c'est une autre affaire).

Voilà le code correspondant à MeineDatenActivity, j'espère que quelqu'un pourra m'aider parce que je suis sur ce problème depuis un petit moment là:

Donc, tu as simplement oublié de déclarer ton Activity dans ton manifest
Fais-le, et tu n'auras plus ce crash

Ps : prend l'habitude de coder en anglais plutôt que dans une autre langue. C'est plus pratique pour tout le monde pour relire

Ok je prends note, plus de programmation en allemnad

Sinon j'ai vérifié dans mon manifeste et j'avais bien déclaré cette activité, regarde:

Alors d'où vient le problème? car j'ai bien déclaré 9 activité pour les 9 créees

[Hizin]

Oui, tu as bien déclaré MeineDatenActivity, mais pas InscriptionActivity
C'est l'absence de déclaration de InscriptionActivity qui fait crasher

[guigui2454000]

Aaaah ça marche! merci beaucoup!
Du coup puis-je en profiter pour te poser une nouvelle question? Car sur cette page de connexion, il y a deux messages qui doivent apparaître en fonction de ce qui est écrit ou pas. Par exemple si je rentre rien dans les champs "email" ou "passwort", je dois avoir un message "email ou mdp vide" et si je ne rentre pas une adresse email dans le champ concerné j'aurai alors le message "format email mauvais" et évidemment si je rentre les bons trucs je me connecte. Or ce qu'il se passe pour le moment c'est que quoi que je fasse (mis à part quand je rentre les bons trucs, ça ça fonctionne) j'ai le message "format email mauvais"....

Je met le code de l'activité concerné:
