[Android] Upload file su server remoto

[ubbicom]

Ciao a tutti.


Sto provando ad eseguire l'upload di una fotografia su un server remoto tramite un webservice in asp net.


Il problema in questa classe java è che anche con la fotografia selezionata del form di invio dati, mi viene sempre restituito l'alert "Please select image".


Perchè cosa sto sbagliando?
Grazie
