FTP:
inside CVS on ftp:
Android Device:
inside the CVS that was imported into the cell phone:
Does anyone know why?
thanks since you
--- EDIT ---
found something, while debugging I noticed what the status in Ftpcontroller in the download method, it is returning false, on this line:
status = mFTP.retrieveFile(arqOrigem, desFileStream);
and the mFTP is null when debug arrives in return status
