android - How to check internet access? -

-

so, question how check if receiving data or not. scenario connected wifi network such starbucks wifi (which user should first connect network , accept agreement before receiving data.) code not serving purpose. 

    connectivitymanager cm =         (connectivitymanager) _mcontext.getsystemservice(context.connectivity_service);     networkinfo netinfo = cm.getactivenetworkinfo();     if (netinfo != null && netinfo.isconnected()) {         return true;     }     return false;

it returns true when connected network have not accepted agreement yet. thanks,

there's no way know that, because isn't handled @ os level- handled @ router. os knows whether has completed handshake router , received ip. whether router going throw him login screen beyond scope of os.
