My app allows the user to white-list contacts. The user is allowed to make calls only to the white-listed contacts.
I have achieved this functionality by saving the white-listed contact information in a SQLite table and displaying them in an activity along with contact photo and name.
When the user clicks a contact, that contact card opens up and a call can be placed to the selected number.
I would like to get rid of the activity that displays the white listed contacts and use the standard contacts app instead.
The contacts app should display only those contacts that have been white listed by the user and hide the contacts that are not white-listed by the user.
How would I achieve this?
