Problem in detecting Internet Connection in Android

Question

I have created a Android application using Google Maps. Now I want to check whether an internet connection is available or not. I search in Google and finally I got solution

Answer 1

Try using NetworkInfo ni = cm.getActiveNetworkInfo(); instead of NetworkInfo ni = cm.getAllNetworkInfo();. There should only be one active data network at any one time because Android will use the best available and shut down the others to conserve battery.

Also, I tend to use ni.isConnectedOrConnecting(); instead of ni.isConnected(); because it can catch transition states better.

I also use ni.getType() == ConnectivityManager.TYPE_WIFI instead of ni.getTypeName().equalsIgnoreCase("WIFI") because it is much more efficient to compare two int values than it is to compare two strings.

The following code works for me:

boolean HaveConnectedWifi = false;
boolean HaveConnectedMobile = false;
ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if ( ni != null )
{
    if (ni.getType() == ConnectivityManager.TYPE_WIFI)
        if (ni.isConnectedOrConnecting())
            HaveConnectedWifi = true;
    if (ni.getType() == ConnectivityManager.TYPE_MOBILE)
        if (ni.isConnectedOrConnecting())
            HaveConnectedMobile = true;
}
