For your problem 2, i see 2 solutions 对于你的问题2,我看到2个解决方案
a. 一种。 If the user unlocks the screen, a message is fired: check at that moment if you are in the area and if not, instantly lock again
如果用户解锁屏幕,则会触发一条消息:如果您在该区域,请检查当时是否存在,如果没有,请立即再次锁定
b. 湾 create your own locksreen with no possibility to unlock yourself
创建自己的锁屏,无法解锁自己
I need to prevent the user from unlocking the phone when he/she is out side the defined WiFi area
当他/她在定义的WiFi区域外时,我需要阻止用户解锁手机
Fortunately, this is not supported, for obvious security reasons. 幸运的是,出于明显的安全原因,这不受支持。
You are welcome to create your own home screen that offers different behavior when inside/outside a defined area and use that in lieu of trying to prevent a phone from being unlocked. 我们欢迎您创建自己的主屏幕,在定义区域内/外提供不同的行为,并使用它来代替试图阻止手机解锁。 However, the user is welcome to remove that home screen by booting their device into safe mode and uninstalling your app.
但是,欢迎用户通过将设备启动到安全模式并卸载应用程序来删除该主屏幕。
