android alarm clock app help!

[Android Question]

Does anyone know how to run an application in front of the lock screen. For example, I am creating this app that plays a video at a certain time. The initial state of the phone is locked. How do I do that? I want to create the same effect as the alarm clock on android in which the alarm clock alerts you even if you have a lock screen.

The apps you see on the lock screen are all widgets, so your app would have to be able to make widgets.

No. What I mean is I want the video to pop up in front of the lock screen exactly like how the alarm clock gui pops up in front of the lock screen.
