Android Address Book Management 1 contact acquisition

As we know, Android address book and SMS management use contentprovider to Develop interfaces for developers. You must start with ContentResolver. The address book operation involves the use of the system source code api, especially on the uri of the table. In the following articles, snail mail will gradually introduce Android communication management knowledge. These include contact acquisition, call record acquisition, SMS retrieval, and SMS details retrieval. Not to mention nonsense first

First look at the structure of the contact table

For development, we mainly focus on the above three tables, including the use of joint queries. for the design of the three tables, we can refer to Baidu to relevant articles.
