Im assez nouveau pour la programmation android d'où j'ai besoin d'aide. Lorsque je lance le programme, il est seulement capable d'afficher la 1ère page (adresse IP dans la page) et quand je clique sur le bouton de connexion, il est incapable d'exécuter l'activité suivanteImpossible d'exécuter CameraView sur l'activité suivante sur les studios android
J'ai ajouté les 3 Manifeste pertinents pour l'autorisation de l'appareil photo & l'utilisation du matériel. Je souhaite que l'utilisateur saisisse l'adresse IP (qui sera vérifiée par rapport au comparateur) et si elle correspond, cela conduira à l'activité suivante qui est la caméra. J'ai essayé d'exécuter individuellement le matcher d'adresse IP et la caméra sur 2 projets différents et ils fonctionnent parfaitement bien.
Sur la note de côté, parfois je reçois sans cesse ce NullPointerException que je pense que j'ai pu fixer avec les instructions if pour mon OnclickListener et ceux addView dans la classe MainActivity
Ceci est ma MainActivity classe
public class MainActivity extends AppCompatActivity
