connection - Problem: Android's isConnected() used to get current state of WiFi often returns false even when the device is connected -

my android app can function wifi connected internet. thus, use following code check if device connected:

connectivitymanager conmgr = (connectivitymanager)getsystemservice(activity.connectivity_service); boolean wifi = conmgr.getnetworkinfo(connectivitymanager.type_wifi).isconnected(); 

however, when application launched , wifi connected internet, notification shown when wifi = false. have missed something, or check not accurate?

i use code this:

public static string getcurrentssid(context context) {   final wifiinfo wifiinfo = getcurrentwifiinfo(context);   if (wifiinfo != null && !stringutil.isblank(wifiinfo.getssid())) {     return wifiinfo.getssid();   }   return null; }  public static wifiinfo getcurrentwifiinfo(context context) {   final connectivitymanager connmanager = (connectivitymanager) context.getsystemservice(context.connectivity_service);   final networkinfo networkinfo = connmanager.getnetworkinfo(connectivitymanager.type_wifi);   if (networkinfo != null && networkinfo.isconnected()) {     final wifimanager wifimanager = (wifimanager) context.getsystemservice(context.wifi_service);     return wifimanager.getconnectioninfo();   }    return null; }
