问题
I want to do a demo just like WaveSecure, which win Android Develop Challenge 2 with a third place. Now I have a problem in locking the screen customly, so I want to know how WaveSecure achieve its locking function, as the following picture show:
When the mobile is locked, WaveSecure can require customer to input their own password. So I think WaveSecure must replace Android's original locking function.
And I also google it, but I didn't find anything helpful. I only find two packages may be helpful. They are:
- android.app.KeyguardManager
- android.os.PowerManager
But after I reading the Android Docs, I still can't have an idea on it.
Can you help me? Thx:)

I have been searching for an answer to the exact same question for a while. Apparently, after 2.0 onwards the device manager privileges for the app level were removed. But with Froyo - 2.2 the device policy manager is revealed granting us developers a multitude of administrative level controls.
