android 連接指定SSID 的無密碼Wifi ，連接不上

"\"" + SSID + "\""

這是干啥？？？
你傳進來的就是 String SSID ，為何還要做隱式轉換成String？
轉換就轉換吧，為啥要這么寫？
這么寫最后SSID是啥？
SSID = "\"" + "ee929" + "\"" = ""ee929"" ???

建議你在
int netId = configuration.networkId;
插入log，打印下你的SSID和password，看看還是不是你要的結果。

失誤了，由于連接的wifi設置為隱藏，所以配置少加了一個
config.hiddenSSID=true; 必須加上，才能連接無法掃描到的wifi
