How to detect slow network connection?
I have a problem about how to detect internet connection , i want if the internet connection has slowly there is show alert dialog or notice about the connection internet slowly.
you can use the below mentioned Connectivity utility class to check if internet connected or speed of the internet connection,
public class Connectivity {
/**
* Get the network info
*
* @param context
* @return
*/

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo();
}

*

* @return
*/

NetworkInfo info = Connectivity.getNetworkInfo(context);
return (info != null && info.isConnected());
}

NetworkInfo info = Connectivity.getNetworkInfo(context);
return (info != null && info.isConnected() && info.getType() == ConnectivityManager.TYPE_WIFI);

NetworkInfo info = Connectivity.getNetworkInfo(context);

}
