problema caricamento file su server da app android
Ciao,
sto cercando di caricare un file immagine da app android (sviluppata con android studio) e ho un problema il codice java rileva il corretto caricamento ma del file non c'è traccia sul server.
Sul mio spazio altervista ho sviluppato il codice php per leggere il file attraverso la variabile $_FILE.
Nel codice php ho aggiunto delle insert ad una mia tabella di log. Ho così scoperto che il php viene correttamente richiamato dalla app ma la variabile $_FILE è sempre vuota . dai log della parte java risulta che scrivo tutti i byte con la write dell'outputstream.
C'è qualche impostazione da fare sul server o qualcuno riesce a suggerirmi cosa sto sbagliando ?
Di seguito il codice php e la parte java di connessione e scrittura stream.
Grazie mille per l'aiuto !
Ciao
