Its a simple application for Android Application for locking the screen.
The phone should unlock by pressing the home button and screen should turn black. There should be no icons displayed. the screen should be completely black.
The user should make Z with his finger tip on the touch screen and his screen will unlock. Thats all that simple.
Payment will only be done once the application is fully working and i have tested it, you need give the source code once the payment is done
Bid only if you can do this in 6 days.
