如何知道用户输入错误的密码或图案? (机器人锁) [英] how to know User have entered wrong password or pattern? (android lock)
问题描述
我想,如果用户输入错误的花样和这个数字看起来的服务。结果
我用Google搜索,但没有什么是有用的。有人说这是不可能的,因为它是Android系统,交通不便,并有一些说这是可能的,他们正在谈论PASSWORD_FAILED企图什么的。结果,我认为这是完全有可能的,因为有一个应用程序时,你输入了错误的模式,它需要有前置摄像头的画面。
结果任何帮助将AP preciated。
I want a service to look if user enters wrong pattern and number of that.
I Googled it, but got nothing useful. some say it's impossible, because it's for Android system and inaccessible, and there are some saying it's possible and they're talking about "PASSWORD_FAILED attempts" or something.
And I think it's completely possible, because there is an app when you enter a wrong pattern, it takes a picture with front camera.
Any help will be appreciated.
推荐答案
一个设备管理员可以使用<钟表登录/>
政策看到这一点。它接收 ACTION_PASSWORD_SUCCEEDED
或 ACTION_PASSWORD_FAILED
每一次,它可以使用 DevicePolicyManager#getCurrentFailedPasswordAttempts
来查询它。
A device administrator can use the <watch-login />
policy to see this. It receives ACTION_PASSWORD_SUCCEEDED
or ACTION_PASSWORD_FAILED
each time, and it can use DevicePolicyManager#getCurrentFailedPasswordAttempts
to query for it.
请参阅设备管理。
