i m having a problem in launching my app after unlock.

I am new to android programming. I am building a Face Recognition unlock System for Android. Anyone, tell me any tutorial or any help about launching my app on just unlocking the device. I am unable to get any help from google. So Please, anyone help me as soon as it is possible.

As my Project is Face Recognition Unlock. It means that if a person unlocks the device, it must launch my app for the purpose of face detection. I have done much work of face detection, but cant launch my app on unlock. JnR

    But you _have_ planned for some extra time to understand the concepts of the new platform, haven't you? -- You may want to look at [Intent.ACTION_USER_PRESENT](http://developer.android.com/reference/android/content/Intent.html#ACTION_USER_PRESENT), though. But I suspect that you may really have a requirement which differs from what you describe. – class stacker Apr 13 '13 at 15:01
