salut à tous,
grâce à deux tuto j'ai reussi à afficher une gallerie de photo chargée à partir de mon SDcard, mais en fait je veux plus précisamment afficher une gallerie de vidéo (aussi se trouvant dans la SDcard)
d'abord est ce que c'est faisable sous android 2.1?
si c'est le cas,quelles sont les modifications que je dois affecter à mon ancien code?
voici le code:
Code : Sélectionner tout - Visualiser dans une fenêtre à part
