Bonjour à tous, j'ai un tel LG KU990 allias Viewty, il est compatible Java et je cherche un explorateur de fichier qui pourait me donnée l'accés a la totalité des données du telephone, j'ai fais des recherche personelle avant de poster sur se forum mais la seule chose que j'ai pu denicher c'est les source d'un example de netbean IDE 6.0 qui s'appel PDAPDemo.
il fonctionne sur mon mobile mais l'accés ne se fais pas a partire de la racine du tel il commance a un certain niveau mais je ne sait pas le quel.
pouvez vous m'aider?
je n'est pas de connaissance en programmation, car l'apprentisage et trés long, et je débute.

je vous joint les sources qui sont, je le répéte, libres.

merci d'avence à ceux qui prendront le temp de me repondre...
