The contacts are stored in a SQLite3 database file so the file format is ".db"
联系人存储在 SQLite3 数据库文件中，因此文件格式为“.db”
The development tool Android Debug Bridge(ADB) can be used to extract the file from an EMULATOR
开发工具Android Debug Bridge(ADB) 可用于从EMULATOR 中提取文件
ADB can also extract the file from a phone but it must be rooted first AND the ADB drivers must be installed on your machine as well
ADB 也可以从手机中提取文件，但必须先植根，并且 ADB 驱动程序也必须安装在您的机器上
(Rooting is NOTfor beginners though)
（虽然生根不适合初学者）
The contacts.db file is stored in the protected system memory, the file path is:
contacts.db 文件存储在受保护的系统内存中，文件路径为：
data/data/com.android.providers.contacts/databases/contacts.db
数据/数据/com.android.providers.contacts/databases/contacts.db

You can access contact information programmatically using ContactsContractand AccountManager(in Android 2.0); there's an example on how to do so in the SDK, called Contact Manager.
您可以使用ContactsContract和AccountManager（在 Android 2.0 中）以编程方式访问联系信息；在 SDK 中有一个关于如何执行此操作的示例，称为Contact Manager。
