android最新联系人信息的存储结构

mimetype_id 表示该行存储的信息的类型
raw_contact_id 表示该行所属的RawContact
is_primary 多个data数据组成一个raw contact，该字段表示此data是否是其所属的raw contact的主data，即其display name会作为raw contact的display name
is_super_primary 该data是否是其所属的contact的主data，如果is_super_primary为1则is_primary一定为1
data1~data15 15个数据字段，对于不同类型的信息，表示不同的含义，ContactsContract.CommomDataKinds类中定义了与常用的数据类型相对应的一些类，这些类中分别定义了相应数据类型中这些字段表示的含义。一般data1表是主信息（如电话，Email地址等），data2表示副信息，data15表示Blob数据。
data_sync1~data_sync4 sync_adapter要用的字段（sync_adapter用于数据的同步，比如你手机中的Gmail帐户与Google服务器的同步）。
data_version 数据的版本，用于数据的同步。

AGGREGATION_MODE_DEFAULT：正常模式，允许自动聚合；
AGGREGATION_MODE_DISABLE：不允许聚合；
AGGREGATION_MODE_SUSPENDED：当一个raw contact的aggregation mode修改为suspended时，如果其已是一个已聚合的contact的一部分，那么它仍会保持与原来聚合到一起的raw contact的关系，即使它已改变不再跟其他raw contact匹配。

TYPE_AUTOMATIC=0　　由系统决定聚合行为，默认值。
TYPE_KEEP_SEPARATE=2　　不聚合
TYPE_KEEP_TOGETHER=1　　聚合
