How to get phone contacts in Android [duplicate]

Answer 1

You may want to look at ContentProviders for the ContactsProvider.

The ContentProvider tutorial even uses Contacts as an example:

the URI for the table that matches phone numbers to people and the URI for the table that holds pictures of people (both controlled by the Contacts content provider) are:

android.provider.Contacts.Phones.CONTENT_URI
android.provider.Contacts.Photos.CONTENT_URI
