Application mobile responsive pour tablette Android studio
Bonjour à tous je suis un jeune codeur et je suis sur un projet de créer une application éducative dans ma langue locale et je l'ai terminer à 100%
Elle fonctionne très bien sur Mobile sur l'émulateur d'Android studio et même sur mon smartphone mais des que je la lance sur l'émulateur en mode Tab 10 l'application ce lance et dès quelle passe de la page de démarrage au Main Activity elle crash, alors que sur la version mobile j'ai pas ce problème. j'ai créer des fichier xml sw320dp pour la version mobile et sw720dp pour la version tablette.
Voici mon code Java
