Android Application Development for Pattern Unlock

Client Requirement:

The client wanted us to develop an Android application for Pattern Unlock that would allow the user to choose a separate pattern screen within the application which we will launch from background whenever the device is idle.

Our Endeavor:

The application is for locking the Android device. The user can choose the unlock pattern image according to his interest. Some of the icons are free, and some are the paid. Payment will be done via Pay pall Android API. We have handled the project from scratch. Initially, we did not have any idea about the pattern locking. We made the sample code for the pattern lock and then integrated the same. We were also stuck in the problem related to controlling the home button. However, our team found the right solution for the same too.
