Manage Android Communication Records

Android provides contacts applications to manage contacts, and the Android system also provides contentprovider for contact management, which allows other applications to contentresolver to manage contact data.

for ContentProvider, Contentresolver and URI details, you can refer to http://blog.csdn.net/fengyuzhengfan/article/details/ 37743963, it's not too much of a statement here!

Send the instance to run first:

Before you work with a contact, let's take a look at the main tables in the Contacts database:

1) Rawcontacts: The id,_id property of the contact person is the primary key, declared as AutoIncrement, that is, no manual setting is required, and other properties do not need to be manually set to have default values;

2) Mimetypes: The type of data stored, such as "Vnd.android.cursor.item/name" for the "name" type of data, "VND.ANDROID.CURSOR.ITEM/PHONE_V2" for "phone" type of data;

Field name	Description
Phone	Vnd.android.cursor.item/phone_v2
Name	Vnd.android.cursor.item/name
Mail	Vnd.android.cursor.item/email_v2
Correspondence Address	Vnd.android.cursor.item/postal-address_v2
Organization	Vnd.android.cursor.item/organization
Photo	Vnd.android.cursor.item/photo

3) data is stored in a specific database.

Field name	Description
data._id	"_ID"
Data.display_name	"Display_name"
Data.data1	"Data1"
Data.data2	"Data2"
data.raw_contact_id	"RAW_CONTACT_ID"
Data.mimetype	"MimeType"

4) The raw_contact_id attribute is used to connect the Raw_contacts table, each record represents a specific data, and our main data (email, phone, etc.) are stored in the datasheet;

5) The main structuredname is the name of the contact, its name and its phonetic name.

When we insert a contact into the correspondence database, we usually insert a blank line to the Rawcontacts table to get the rawcontactid that is the contact ID, and then insert the contact's name, phone number, and email information into the data table based on that ID.
