A simple lock screen library that secures access to an application.
To use, simply set your app to use SecuredApplication as its Application class:
<application
android:name="com.sarbs.knockknock.SecuredApplication">
...
...If you already have an Application subclass, then just insert SecuredApplication into the inheritance chain
somewhere. Once that's done, call SecuredApplication.launchSetPasscodeActivity(Activity start) in order to allow
the user to set their PIN, and SecuredApplication.clearPasscode(Context ctx) to clear it. While a PIN is set,
the app will force the user to authenticate anytime they've left the app for more than ten seconds.
If you want a particular activity to be exempt from the PIN lock, make it implement the marker interface LockScreen .
