android - Check connectivity to internet, hangs UI with bad signal -


i'm trying check connectivity(wifi or cellular) internetwith method called onstart method:

public static boolean isinternetconn(context ctx){          connectivitymanager connec = (connectivitymanager) ctx.getsystemservice(context.connectivity_service);         android.net.networkinfo wifi = connec.getnetworkinfo(connectivitymanager.type_wifi);         android.net.networkinfo mobile = connec.getnetworkinfo(connectivitymanager.type_mobile);          boolean connected= false;         if((wifi != null && wifi.isconnectedorconnecting()) || (mobile != null && mobile.isconnectedorconnecting())){                 try {                  strictmode.threadpolicy policy = new strictmode.threadpolicy.builder().permitall().build();                              strictmode.setthreadpolicy(policy);                 url myurl = new url("http://www.google.com");                 urlconnection connection;                 connection = myurl.openconnection();                 connection.setconnecttimeout(2000);                 connection.setreadtimeout(2000);                 httpurlconnection httpconnection = (httpurlconnection) connection;                 int responsecode = -1;                 responsecode = httpconnection.getresponsecode();                 if (responsecode == httpurlconnection.http_ok) {                       connected = true;                       httpconnection.disconnect();                 }                 else {                     httpconnection.disconnect();                 }              } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();                             }         }        return connected;     }

if net signal low method hangs ui , ui becomes black. i've configured timeouts low value , problem still happening. it's recommende task in async task?

thanks

looks trying ping google check network connectivity. unnecessary , doing network operations on main thread disrupt ui. use following method instead:

public boolean isconnectingtointernet(context context) {     connectivitymanager connectivity = (connectivitymanager) context.getsystemservice(context.connectivity_service);     if (connectivity != null) {         networkinfo[] info = connectivity.getallnetworkinfo();         if (info != null)             (int = 0; < info.length; i++)                 if (info[i].getstate() == networkinfo.state.connected) {                     return true;                 }     }     return false; }

remember add access_network_state , internet permissions in manifest

edit : check quality of network, use this library created facebook. categorizes connection quality poor (below 150 kbps), moderate (between 150 , 550 kbps), (between 550 , 2000 kbps) , excellant (over 2000 kbps).
