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?

  • I have edited your question to improve the grammar and layout to try and get more traction for answers. Your questions is an interesting one, but it isn't a great fit for SO because it isn't focused on a specific issue you have hit while developing this solution and appears to be asking for a tutorial on the general concepts you will need to understand to achieve your solution. Consider re-writing the question to give succinct code examples of exactly what you are having problems with. – lukkea Apr 19 '17 at 15:58
