Question

I have little issue with detecting internet connection while using static IP on device. While I’m connecting without setting any static ip my function for detecting available connection is working properly. But when I set static IP, the function return true, because I’m connected to Wifi or 3G, but I don’t have any internet connection and so my app crashes in that situation. Any ideas how to fix that problem while using static ip?
Here is what I’m using :

public boolean chkNetworkStatus(Context context) {
     ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
     if (connectivity == null) {
         Toast.makeText(context, "No available connection!", Toast.LENGTH_LONG);
     } else {
         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; 
}

Here is what you can use in your situation. This function will return true if you are connected to wifi/3g and you can load any web page.

    public static boolean isOnline(Context context) {
         ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
         NetworkInfo netInfo = cm.getActiveNetworkInfo();
        if (netInfo != null && netInfo.isConnectedOrConnecting()) {
            return true;
        }
        return false;
    }

    public static boolean chkNetworkStatus(Context context) {
    boolean result = false;
    new Thread() {
        @Override
        public void run() {


           for(int i=0;i<3;i++){
           HttpGet requestForTest = new HttpGet("http://m.google.com");
           try {
                  new DefaultHttpClient().execute(requestForTest);
                  responded = true;
                } catch (Exception e) {
                    responded = false;
                }
           }
        }
    }.start();
    boolean isOnline = isOnline(context);
    if(responded && isOnline){
        result = true;
    } else {
        result = false;
    }

    Log.e("","responded : "+responded);
    return result;
}
