Google Home应用程序如何在Android上自动获取wifi密码？
[英]how google home app can auto fetch wifi password on android?
问题描述
As you and I already know, All apps on the android can't read other app's data basically without root. 
正如您和我已经知道的那样，Android上的所有应用程序基本上都无法在没有root的情况下读取其他应用程序的数据。 (since sandbox system.) （由于使用了沙箱系统。）
But recently released google Home app read saved wifi password on the phone and connect device with its password . 但是最近发布的Google Home应用读取了手机上保存的wifi密码，并使用其密码连接设备。 How can it be? 怎么会这样？ I couldn't understand this behavior is possible. 我不明白这种行为是可能的。
I confirmed that works even though I logged out google account. 即使我注销了Google帐户，我也确认该方法有效。 (It means wifi password is coming from local device's saved configuration). （这意味着wifi密码来自本地设备的已保存配置）。
Google announced that auto fetch feature works after lollipop only. Google宣布自动获取功能仅在棒棒糖之后可用。
