Contacts Eraser description
Contacts Eraser is an app for the quick deletion of your contacts. The main difference with other apps is the possibility to trigger the deletion via intent (android internal messages). You can
configure your automation app (for example Llama, Tasker, and so on) to send an ad-hoc message event-based.
Typical use case? For example it can be used for security and privacy. You can delete all your contacts if someone tries to unlock your phone without any authorization. After a configurable number of
failed login you can delete all your contacts.

Note: Starting from Android 3.1, applications can't receive a broadcast intent if not manually started by the user at least one time. I suggest you to start at least one time the app after the
installation.
