Android providers 解析之telephony
Android providers的源代码结构如下:
android-2.2-froyo/ com/ android/ providers：
- [applications]
- [calendar]
- [contacts]
- [downloads]
- [drm]
- [media]
- [settings]
- [telephony]
- [userdictionary]
本篇来解析一下telephony这个provider中的代码，首先来看一下它的目录结构：
android-2.2-froyo/ com/ android/ providers/ telephony：
- MmsProvider.java
- MmsSmsDatabaseHelper.java
- MmsSmsProvider.java
- SmsProvider.java
- TelephonyProvider.java
- Telephony.java (隐藏类，在Android 的source源代码中可以找到，如：sources\android-14\android\provider\Telephony.java )
以上6个类可以划分为3类：
第一类：数据库管理工具类 (A helper class to manage database)，包括：MmsSmsDatabaseHelper.java
第二类：与电话操作相关数据类，包括：Telephony，它是个特殊的类，隐藏类
第三类：内容提供者 (ContentProvider)，包括：MmsProvider.java、SmsProvider.java、MmsSmsProvider.java、TelephonyProvider.java，它们都继承于ContentProvider。
下面分别讲解一下以上三大类别的代码：
一、MmsSmsDatabaseHelper.java
由于它的代码有2828行，不宜贴出，这里抽取几个重要变量和方法来解析一下，
public class MmsSmsDatabaseHelper extends SQLiteOpenHelper 说明它是作为数据库管理工具类，
static final String DATABASE_NAME = "mmssms.db";
/// M: Code analyze 006, unknown, for database upgrade.
static final int DATABASE_VERSION = 560000;
这里定义了数据库的名称和初始化版本。
/// M: Add for ip message @{
// this need be the first because it is used by later final consts.
private static final String UPDATE_THREAD_READ_COUNT =
" UPDATE threads SET readcount = " +
" (SELECT count(_id)FROM " +
" (SELECT DISTINCT date * 1 AS normalized_date, _id, read FROM sms " +
" WHERE ((read=1) AND thread_id = new.thread_id AND (type != 3)) " +
" UNION SELECT DISTINCT date * 1000 AS normalized_date, pdu._id, read " +
" FROM pdu LEFT JOIN pending_msgs ON pdu._id = pending_msgs.msg_id " +
" WHERE ((read=1) AND thread_id = new.thread_id AND msg_box != 3 AND (msg_box != 3 " +
" AND (m_type = 128 OR m_type = 132 OR m_type = 130)))" +
" UNION SELECT DISTINCT date * 1 AS normalized_date, _id, read FROM cellbroadcast " +
" WHERE ((read=1) AND thread_id = new.thread_id) ORDER BY normalized_date ASC)) " +
" WHERE threads._id = new.thread_id; ";
其中还定义了类似的数据库语句的final型变量，如：UPDATE_THREAD_READ_COUNT_OLD、SMS_UPDATE_THREAD_READ_BODY、UPDATE_THREAD_COUNT_ON_NEW、UPDATE_THREAD_COUNT_ON_OLD、SMS_UPDATE_THREAD_DATE_SNIPPET_COUNT_ON_UPDATE等。
二、Telephony.java
The Telephony provider contains data related to phone operation.
该类的outline:
该类中定义了几个非常重要的内部类，在MmsProvider，SmsProvider，MmsSmsProvider中会用到。
1、接口 TextBasedSmsColumns：Base columns for tables that contain text based SMSs.
2、接口 BaseMmsColumns ：Base columns for tables that contain MMSs.
public interface BaseMmsColumns extends BaseColumns 它继承BaseColumns这个接口。
3、接口 CanonicalAddressesColumns ：Columns for the "canonical_addresses" table used by MMS and
* SMS."
public interface CanonicalAddressesColumns extends BaseColumns。
4、接口 ThreadsColumns ：Columns for the "threads" table used by MMS and SMS.
public interface ThreadsColumns extends BaseColumns.
5、类 Sms：
类结构截图

三、SmsProvider.java
The class to provide base facility to access MMS related content, which is stored in a SQLite database and in the file system.
短信的uri以content://sms开头。
可以使用Telephony中的Sms类提供的公共变量进行构造Uri，甚至使用其中提供的一些addMessage（将信息存入各个不同的信箱）、saveMessage（更新已存在的草稿）、addMessageToUri（插入数据到指定Uri）、moveMessageToFolder（将信息移到某一信箱）方法简化操作。
UriMatcher中配置了27种类型：
