Example of Android programming method for operating mobile phone address book

This paper describes the method of Android programming to operate mobile phone address book. Share with you for your reference, as follows:

The operation of mobile phone address book is often used, such as adding contacts, deleting contacts or obtaining contact information. Similar operations include the operation of favorites. Here is a small example of the operation of address book. Similarly, the knowledge of the content provider will be used this time.

1. To operate the address book, you must be authorized, that is, the right to read or write the address book. JUnit also needs to be used here

2. Start to get the contents in the address book, mainly the name, number and email

You can see from this query process that there are actually two tables, one with ID and name, and the other with number, email and other information. ID is the primary key, and the following tables use it as the foreign key. As for deletion and other operations, you can read the document yourself. I won't say it here.
