Testing of Network Connection can be done by following method:

 public boolean isNetworkAvailable() 
{
    ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo networkInfo = cm.getActiveNetworkInfo();

    if (networkInfo != null && networkInfo.isConnected())
    {
        return true;
    }
    return false;
}

But i don't know how to check the server connection.I had followed this method

public boolean isConnectedToServer(String url, long timeout) {
try{
    URL myUrl = new URL(url);
    URLConnection connection = myUrl.openConnection();
    connection.setConnectTimetout(timeout);
    connection.connect();
    return true;
} catch (Exception e) {
    // Handle your exceptions
    return false;
}

}

it doesn't works....Any Ideas Guys!!
