internet-connection

I want to execute my application offline also, so I need to check if currently an internet connection is available or not. Can anybody tell me how to check if internet is available or not in android? Give sample code. I tried with the code below and checked using an emulator but it's not working public boolean isInternetConnection() { ConnectivityManager connectivityManager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE); return connectivityManager.getActiveNetworkInfo().isConnectedOrConnecting(); } Thanks binnyb This will tell if you're connected to a network:

For iOS 9 I was using Reachability public class to check wether the device is connected to the internet or not. I converted my Swift 2 code to Swift 3, and the Reachability doesn't work anymore. Can someone tell me how to check the internet connection on iOS 10? Thanks! Here's the code snippet: open class Reachability { class func isConnectedToNetwork() -> Bool { var zeroAddress = sockaddr_in() zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress)) zeroAddress.sin_family = sa_family_t(AF_INET) let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {

I have a C# code that basically uploads a file via FTP protocol (using FtpWebRequest ). I'd like, however, to first determine whether there is a working internet connection before trying to upload the file (since, if there isn't there is no point in trying, the software should just sleep for a time and check again). Is there an easy way to do it or should I just try to upload the file and in case it failed just try again, assuming the network connection was down? Just use the plain function System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable() that return true of false if the

I've been using a 3G wireless card for a while and every time I connect, my anti-virus fires up the updates. I'm wondering what is the Win32 API set of functions that I can use to, either, get notified or query about the event of an Internet Connection coming up? And is there already a set of ported headers for Delphi? I worked on a project to run a user's logon script whenever they connected our network over VPN. To do this, I wrote a helper unit that retrieves adapter info and stores it into a simple record. I then setup up a registry notification, see here for how to do that in Delphi The

Possible Duplicate: How to check if internet connection is present in java? I want to see if anyone has an easy way of detecting if there is an internet connection when using Java. The current app used the "InternetGetConnectedState" method in the WinInit DLL for windows, but my app needs to be cross-platform for mac operation and this way will not work. I do not know JNI at all either to use DLLs in Java and it became frustrating fast. Only ways I could think of were tring to open a URL connection to a website and if that fails, return false. My other way is below, but I didn't know if this
