    Try This.

    ConnectivityManager cman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
            Method[] methods = cman.getClass().getMethods();
    
            try
            {
                wifiManager.setWifiEnabled(false);
                Method enableWifi = wifiManager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);
                String ssid  =   " " //your SSID 
                String pass  =   " " // your Password
                WifiConfiguration  myConfig =  new WifiConfiguration();
                myConfig.SSID = ssid;
                myConfig.preSharedKey  = pass ;
                myConfig.status = WifiConfiguration.Status.ENABLED;
                myConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
                myConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
                myConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
                myConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); 
                myConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); 
                myConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); 
                myConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
                result = (Boolean) enableWifi.invoke(wifiManager, myConfig, true);
    
            } 
            catch (Exception e) 
            {
                e.printStackTrace();
                result = false;
            }
    

    In case of your exception try add this permission to your Manifest android.permission.WRITE_SETTINGS
