Chaque fois que je démarre mon application, elle continue de se bloquer. Comme j'ai eu des problèmes similaires dans le passé avec le RelativeLayout, je suppose que le problème est lié à cela. J'ai créé la mise en page avec l'interface graphique. Ni l'application Java, ni la mise en page ne renvoient d'erreurs ou d'avertissements importants.Crash continu dans l'application Android

pouvez-vous indiquer la ligne 24 dans MainActivity.java. c'est là que l'erreur se produit. –
Veuillez ajouter votre fichier AndroidManifest.xml. Il semble que votre activité ne soit pas déclarée correctement. – Minsky
il semble que vous ayez une 'ClassCastException' lors de l'initialisation de votre' TextView' et que votre wml semble aller bien .. avez-vous essayé de nettoyer votre projet? –
