How to get contacts from contact list in Android? using Contact Provider

I had to fetch contact list from android using contact provider, but it was showing me duplicate entries. So, How can I filter those duplicate entries.

For example, ABCD - 123467890, 1234567890, 1234567890

how to filter duplicate phone number using contact Provider?

And Can I fetch only phone memory contact list?

Solution

  • It is obvious to get duplicate contacts when you fetch them. Since, same contact (same number, different name or different number, same name) might be stored in either in google contacts, phone contacts or in sim contacts.

    In order to eliminate duplicates in your application, use local database (SQLite provided by android) and make phone number as unique, no duplicates will be stored.
