Android Wifi控制方法总结,androidwifi

写了一个工具类来辅助处理wifi相关状态控制和连接等功能,参考了网上的相关文件,并修改了里面的一些bug和问题,本文给出的方法均经过验证可用~

以上~


AAAroid开发的WIFI控制

wifiConfigurations为空了吧。getConfiguredNetworks()的说明

Upon failure to fetch or when when Wi-Fi is turned off, it can be null.
获取失败或wifi关闭时候,返回null
 
android怎控制只可以连接固定的wifi

把自动搜索关了,所以已经记录的WIFI热点都删掉,机器里应该叫遗忘吧
