Screen personal lock
<p>How to bring up a constantly appearing screen in android, user should not be able to get rid of it unless he enters the correct password. None of the keypad,touch screen window should be enabled for user to get rid of this screen. I am trying to develop app for user security. 
Once User will starts this app. no one else can access his personal data. Thank you. any small hint , pointers are appreciated. </p>
