此代码适用于android lollipop但不适用于marshmallow。不能使用在连接到下一个Wifi网络之前删除已保存的密码棉花糖

在android M中以编程方式更改wifi配置的开发？删除保存的wifiaswords无法正常工作

Answer 1

如果您尝试在android-M上根据此文档https://developer.android.com/guide/topics/security/permissions.html#normal-dangerous使用任何危险权限。您需要在运行时请求权限才能在android-M.上使用它们。使用此链接执行此操作：https://developer.android.com/training/permissions/requesting.html
