I am having an application which uses internet connection for receiving data from webservice. But at times of no internet connection my app is forcibly closed.So to prevent this I want to check whether the device is connected to internet or not.

Java

private boolean isNetworkAvailable() {
    ConnectivityManager connectivityManager 
          = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
    return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

I have tried the above most common code from google, but problem with that is that even with no internet connection it returns that the device is having internet. Please help me with some working code.

Hi Kartik, Please refer to below code for checking internet connection.

Java

public boolean isConnectingToInternet(){
     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;
 }
