Question

Hi I’m using this snippet from android

public boolean isOnline() {
    ConnectivityManager connMgr = (ConnectivityManager) 
    getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = connMgr.getActiveNetworkInfo();
    return (networkInfo != null && networkInfo.isConnected());
}  

But when I interrupt the internet connection from my desktop it won’t find that isn’t connected,and try to connect. I’m running it in the Android emulator. My question:why it won’t return false and still figures out that it is connected?if it was connected through 3D shouldn’t it get the data?

Answer 1

public class Networking {
 /*
 *@return boolean return true if the application can access the internet
 */
 public static boolean isNetworkAvailable(Context context) {
     ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
     if (connectivity != null) {
        NetworkInfo[] info = connectivity.getAllNetworkInfo();
        if (info != null) {
           for (int i = 0; i < info.length; i++) {
              if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                 return true;
              }
           }
        }
     }
     return false;
  }
}
