internet-connection

I have a requirement where I want to check whether there is any internet connectivity when I am connected with the network. For example, I have device A and device B. Device A is connected with hotspot with that of device B. In device A, I get it as connected with Wi-Fi and in device B - one device connected with hotspot. Now, if I remove the internet from device B (not the tethering hotspot), then in device A, it still shows - connected with Wi-Fi but there is no internet connectivity. Classes like ConnectivityManager help in determining whether a device is connected with the network not

I am trying to check Internet connectivity on Android using the following method. I have a Wi-Fi connection. private boolean checkInternetConnection() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); // Test for connection if (cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isAvailable() && cm.getActiveNetworkInfo().isConnected()) { return true; } else { // No conection return false; } } I disconnect my PC from the Internet and then try to run the above method. Still it always returns true!? Why? MKJParekh From Eclipse To disable

Im on an application that receive data from server, the problem is when user connect to cellular data (Not 3G or WIFI ), it take ages to receive data. i had implemented this code from this Answer but im not sure if it is effective or not, sometimes it's giving me an accurate type, and sometimes it don't. here is my code: - (void)newtworkType { NSArray *subviews = [[[[UIApplication sharedApplication] valueForKey:@"statusBar"] valueForKey:@"foregroundView"]subviews]; NSNumber *dataNetworkItemView = nil; for (id subview in subviews) { if([subview isKindOfClass:[NSClassFromString(@

I have a problem with checking internet connection in android at runtime. I use some different methods to check internet connection but i don't know which one is better . because each of them have some problems . Method 1 check internet connection by pinging Google : Runtime runtime = Runtime.getRuntime(); try { Process mIpAddressProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8"); int mExitValue = mIpAddressProcess.waitFor(); return mExitValue == 0; } catch (InterruptedException | IOException ignore) { ignore.printStackTrace(); } Method 2 check internet connection by ConnectivityManager :

This is what I would like to do : => IF WiFi is enabled AND active, launch an intent (in fact it's a WebView that gets its content=>the instructions of my app on the web) => IF NOT, then I would launch another intent so that I don't show a WebView with "Web page not available ... The Web page at http://www.mywebsite.com might be temporarily down or it may have moved ..." I tought initially to use if(wifi.isWifiEnabled()) but that does not say if the Wifi connection is ACTIVE or not. It says only that the user has turned the switch on. The device may or may not be connected... Is this correct ?

Just asked how to check if an internet connection exists using javascript and got some great answers. What's the easiest way to do this in Ruby? In trying to make generated html markup code as clean as possible, I'd like to conditionally render the script tag for javascript files depending on whether or not an internet condition. Something like (this is HAML): - if internet_connection? %script{:src => "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", :type => "text/javascript"} - else %script{:src => "/shared/javascripts/jquery/jquery.js", :type => "text/javascript"} You can
