Avez vous une idée du problème?

Tu sature la mémoire de la machine virtuelle.
Tu devrais vérifier si tu n’instancie pas trop d'objet. Ou si il n'y as pas une conservation de référence sur des objets volumineux.

Cordialement,
Patrick Kolodziejczyk.

Merci beaucoup pour ta réponse.

J'instancie juste un gridview avec des images donc je ne pense pas que ça soit trop volumineux mais qu'entends tu par " une conservation de référence sur des objets volumineux"?

En java tu ne détruis pas les objets. Ils sont conservés en mémoire tant qu'il y a une référence vers eux. Le rôle du "garbage collector" (gc) est de faire le tri en mémoire et dessaoulé la mémoire lié à des objets non référencés.
Quand tu as un "Out of memory"; Il y a deux causes possibles :
Tu cherche a avoir plus d'objet en mémoire que la mémoire peut en contenir.
Tu conserve des références sur des objets que tu ne considère plus comme utile.

Typiquement ça va être ton main qui conserve une référence sur l'écran précédent et donc l'ensemble des objets (et images) associées.
C'est une erreur courant en Java, comme le NullPointerException.
