What I have thought that i can display an error when there no internet connection available but I dont know the way to do it.

Answer 1

Check out my HTTPclass.java class, how I did that, I have a method connect(url) that takes a String of url and connects it, if connection is received it responds and gives the responseCode = 200 or HTTP.OK, and if the connection is not connected I handle a catch block and set the responseCode = -1 which means its not connected.

So, you can do something like that only. When responsecode is -1 you can show the Message that “Internet Not Connected”.

public class HTTPClass
{
    private static int responseCode = -1;
    private static HttpURLConnection httpconn = null;        
    private static URLConnection conn = null;
    private static URL urlobj;

    public static int connect(String url) throws IOException
    {
        try
        {
            urlobj = new URL(url);
            conn = urlobj.openConnection();
            httpconn= (HttpURLConnection)conn;
            httpconn.setConnectTimeout(5000);
            httpconn.setDoInput(true);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
        try
        {
            responseCode = httpconn.getResponseCode();
        }
        catch(Exception e)
        {
            responseCode = -1;
            e.printStackTrace();
        }
        return responseCode;
    }
}
