I have written an app that sends a file to a laptop via Bluetooth. I would like to be able to delete that file automatically after some confirmation that the file was sent successfully. I get a Toast message from BlueTooth Share that the file was sent, but how can I detect this from my app? Is there a callback that I can use for this? Here is my method for sending the file using Android 4+ File filename = new File(path + "/" + itemValue); Uri uri = Uri.fromFile(filename); //send file via bluetooth Intent intent = new Intent(Intent.ACTION_SEND); intent.setType("text/*"); //this causes us to

navigator.camera.getPicure function not working. Its callback function never gets fired in below code. This function is from cordova camera plugin. navigator.camera.getPicture( uploadPhoto, function(message) { alert('Failed to get a picture. Please select one.'); }, { quality : 50, destinationType : Camera.DestinationType.FILE_URI, sourceType : Camera.PictureSourceType.SAVEDPHOTOALBUM }); In the above code uploadPhoto callback function never gets fired. And there is no traces of it in chrome dev tools console when the above function is called it opens the file selection window and after the

I'm trying to receive some file through sockets in C. But the server sends me 64-byte packets for a 1000000 byte file for example and I get approximately 999902 bytes on the destination file. while ((n = read(sd, buffer_in, BUFSIZE ))) // BUFSIZE = 64 { if(n<0) { printf("Fail.\n"); fclose(archivo); return -1; } if(fwrite(buffer_in, n, 1, f) !=1 ) { printf("fwrite error.\n"); fclose(archivo); return -1; } bytes+=n; } printf("We received %d bytes", bytes); When used through a local TCP/IP socket it works, but not in a slow connection. I see through debugging that I get a lot of 64 byte chunks,

Im trying to download daily a backup file from my server to my local storage server, but i got some problems. I wrote this code (removed the useless parts, as the email function): import os from time import strftime from ftplib import FTP import smtplib from email.MIMEMultipart import MIMEMultipart from email.MIMEBase import MIMEBase from email.MIMEText import MIMEText from email import Encoders day = strftime("%d") today = strftime("%d-%m-%Y") link = FTP(ftphost) link.login(passwd = ftp_pass, user = ftp_user) link.cwd(file_path) link.retrbinary('RETR ' + file_name, open('/var/backups/backup-

Is it possible to transfer files between a Mac app and a iOS app? I want to transfer files that are in the documents directory in my iOS App to my Mac App via Wifi, how could I do it? Well, as of iOS 5 onwards, there's iCloud. Since that's still under NDA, I'll just have to point to the relevant documentation and let you read up on your own. If not, I'd consider using the fabulous Dropbox APIs. This does require your users signing up for a Dropbox account, but then you get automatic two-way syncing between their Mac (or PC) and their iOS devices. Failing that, there's always Bonjour . Properly

Introduction Say that on the same local network we have two Node JS servers set up with Express: Server A for API and Server F for form. Server A is an API server where it takes the request and saves it to MongoDB database (files are stored as Buffer and their details as other fields) Server F serves up a form, handles the form post and sends the form's data to Server A. What is the most efficient way to send files between two NodeJS servers where the receiving server is Express API? Where does the file size matter? 1. HTTP Way If the files I'm sending are PDF files (that won't exceed 50mb) is
