短信 sms
文件 /data/data/com.android.providers.telephony/databases/mmssms.db
这个数据库有13张表，sms表存了短信信息。

sms表的uri是
Java代码
public static final Uri CONTENT_URI =
Uri.parse("content://sms");

表项含义，我猜的
0 _id
1 thread_id 在短信界面里显示在第几组（相同联系人的短信在同意行），英文名叫话题。
2 address 电话好吗
3 person ? 存在电话簿里的名字。可能吧
4 date 日期
5 protocol ?..
6 read ? 1- 已读 0-未读
7 status ?
8 type ? 2 我发送
9 reply_path_present ?
10 subject
11 body 短信内容
12 service_center ...

好没信息量。。。。

把源码补上。
在frameworks/base/core/java/android/provider/Telephony.java

Java代码
/**

*/
public static final String THREAD_ID = "thread_id";

2、part表
mmssms.db库中的part表存储了彩信内容（文本、音乐、图象）的文件名（即上面将的app_parts下面的文件名）、文件类型信息。
其中“mid”对应着pdu表中的“_id”，“ct”是文件类型，“_data”是存储路径。

3 。彩信文件读取

彩信附件文件的地址存储在mmssms.db的part表的_data字段，形如“/data/data/com.android.providers.telephony/app_parts/PART_1262693697763”，但在应用中读取彩信附件时，这个字段基本没什么用，因为不能直接读取这个文件。读取同样要通过ContentProvider，URI为“content://mms/part”，该URI就是对应着part表。可以使用下列代码段来读取文件：
String selection = new String("mid='" + key + "'");//这个key就是pdu里面的_id。
Cursor cur = getContentResolver().query(Uri.parse("content://mms/part"), null, selection, null, null);

if (cur.moveToFirst())
do {
int _partID = cur.getInt(cur.getColumnIndex("_id"));
String partID = String.valueOf(_partID);
Uri partURI = Uri.parse("content://mms/part/" + partID);

ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream is = null;

try {
is = getContentResolver().openInputStream(partURI);
byte[] buffer = new byte[256];
int len = is.read(buffer);
while (len >= 0)
{
baos.write(buffer, 0, len);
len = is.read(buffer);
}
} catch (IOException e) {
} finally {
if (is != null) {
try {
is.close();
} catch (IOException e) {

}
}
}
}
这里得到的baos，就是附件文件。
