How can my app change the network to another WiFi in android 6.0 mobilephone? -

process below (test on platform android api level =23 android 6.0 mobilephone):

1. in app :

   mwifimanager.addnetwork(wcg); boolean b = mwifimanager.enablenetwork(wcgid, true); 

   but b return false;

   log print:

   not authorized remove network  ...... not authorized update network   

2. then try method in wifimanager(marked @hide):

   connect(int networkid, actionlistener listener)  

   by reflectmethod , result failed . print as:

   java.lang.reflect.invocationtargetexception 

in lollipop should try checking active ssid same otherwise disable network.

 int netid = mwifimanager.addnetwork(conf); if (netid == -1) {                     librelogger.d(this, "failed set settings  " + mnetworkssidtoconnect);                     final list<wificonfiguration> mwificonfiguration = mwifimanager.getconfigurednetworks();                     (int = 0; < mwificonfiguration.size(); i++) {                         string configssid = mwificonfiguration.get(i).ssid;                         librelogger.d(this, "config ssid" + configssid + "active ssid" + conf.ssid);                         netid = mwificonfiguration.get(i).networkid;                         if (configssid.equals(conf.ssid)) {                             librelogger.d(this, "network id" + netid);                             break;                         } else {             **/*if ssid not same disable other network here */**                             mwifimanager.disablenetwork(netid);                         }                     }                 }
