Android-contentprovider reading and inserting phone contacts

Target effect:

First in the simulator casually add two contacts, run the program, and then open the contact, found more contacts "Zhang San", and the log output three to Anxi person's name and mobile phone number and number type. (Run multiple times, so the ID inserted is not 3)

The 1.activity_main.xml page is temporarily unavailable, so there is no need to change it.

2.mainactivity.java pages to write queries and add methods.

Mainactivity.java page:

3. The operation contact needs to obtain the permission, therefore in the Androidmainfest.xml page in the Permissions column to add.

4. The program runs to show the target effect.
