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。
短信收件箱对应的URI是content://sms/inbox
很简单吧，就是sms短信，然后inbox收件箱,类似，短信里面的URI分别是
content://sms/
content://sms/inbox
content://sms/sent
content://sms/draft
content://sms/outbox
content://sms/failed
content://sms/queued
android.provider.Telephony:

thread_id 序号，同一发信人的id相同
address 发件人手机号码
person 联系人列表里的序号，陌生人为null (不稳定无法获取联系人ID)
date 发件日期
protocol 协议，分为： 0 SMS_RPOTO, 1 MMS_PROTO
read 是否阅读 0未读， 1已读
status 状态 -1接收，0 complete, 64 pending, 128 failed
type
ALL = 0;
INBOX = 1;
SENT = 2;
DRAFT = 3;
OUTBOX = 4;
FAILED = 5;
QUEUED = 6;
body 短信内容
service_center 短信服务中心号码编号
subject 短信的主题
reply_path_present TP-Reply-Path
locked
Url中content://sms 替换成content://sms/ 也成功，但是其它url时程序报错，比如content://sms/inbox
看了一下android的源代码，sms支持的协议有：
sURLMatcher.addURI("sms", null, SMS_ALL);
sURLMatcher.addURI("sms", "#", SMS_ALL_ID);
sURLMatcher.addURI("sms", "inbox", SMS_INBOX);
sURLMatcher.addURI("sms", "inbox/#", SMS_INBOX_ID);
sURLMatcher.addURI("sms", "sent", SMS_SENT);
sURLMatcher.addURI("sms", "sent/#", SMS_SENT_ID);
sURLMatcher.addURI("sms", "draft", SMS_DRAFT);
sURLMatcher.addURI("sms", "draft/#", SMS_DRAFT_ID);
sURLMatcher.addURI("sms", "outbox", SMS_OUTBOX);
sURLMatcher.addURI("sms", "outbox/#", SMS_OUTBOX_ID);
sURLMatcher.addURI("sms", "undelivered", SMS_UNDELIVERED);
sURLMatcher.addURI("sms", "failed", SMS_FAILED);
sURLMatcher.addURI("sms", "failed/#", SMS_FAILED_ID);
sURLMatcher.addURI("sms", "queued", SMS_QUEUED);
sURLMatcher.addURI("sms", "conversations", SMS_CONVERSATIONS);
sURLMatcher.addURI("sms", "conversations/*", SMS_CONVERSATIONS_ID);
sURLMatcher.addURI("sms", "raw", SMS_RAW_MESSAGE);
sURLMatcher.addURI("sms", "attachments", SMS_ATTACHMENT);
sURLMatcher.addURI("sms", "attachments/#", SMS_ATTACHMENT_ID);
sURLMatcher.addURI("sms", "threadID", SMS_NEW_THREAD_ID);
sURLMatcher.addURI("sms", "threadID/*", SMS_QUERY_THREAD_ID);
sURLMatcher.addURI("sms", "status/#", SMS_STATUS_ID);
sURLMatcher.addURI("sms", "sr_pending", SMS_STATUS_PENDING);
sURLMatcher.addURI("sms", "sim", SMS_ALL_SIM);
sURLMatcher.addURI("sms", "sim/#", SMS_SIM);
--------------------------------------------------------------------------------
其中，delete方法中支持的协议为：
SMS_ALL 根据参数中的条件删除sms表数据
SMS_ALL_ID 根据_id删除sms表数据
SMS_CONVERSATIONS_ID 根据thread_id删除sms表数据，可以带其它条件
SMS_RAW_MESSAGE 根据参数中的条件删除 raw表
SMS_STATUS_PENDING 根据参数中的条件删除 sr_pending表
SMS_SIM 从Sim卡上删除数据
试一下SMS_CONVERSATIONS_ID："
在eclipse中的Emulator Control中，以13800给模拟器发送三条数据，然后以13900发送一条
this.getContentResolver().delete(Uri.parse("content://sms/conversations/3"), "_id=?", new String[]{"5"});
成功删除一条数据。
在数据库中每个发送者的thread_id虽然一样，但不是固定的，如果把一个发送者的全部数据删除掉，
然后换一个新号码发送短信时，thread_id是以数据库中最大的id+1赋值的。
--------------------------------------------------------------------------------
update支持的协议有很多：
SMS_RAW_MESSAGE
SMS_STATUS_PENDING
SMS_ALL
SMS_FAILED
SMS_QUEUED
SMS_INBOX
SMS_SENT
SMS_DRAFT
SMS_OUTBOX
SMS_CONVERSATIONS
SMS_ALL_ID
SMS_INBOX_ID
SMS_FAILED_ID
SMS_SENT_ID
SMS_DRAFT_ID
SMS_OUTBOX_ID
SMS_CONVERSATIONS_ID
SMS_STATUS_ID
以SMS_INBOX_ID测试一下：
ContentValues cv = new ContentValues();
cv.put("thread_id", "2");
cv.put("address", "00000");
cv.put("person", "11");
cv.put("date", "11111111");
this.getContentResolver().update(Uri.parse("content://sms/inbox/4"), cv, null, null);
太强了，连thread_id都可以修改。
--------------------------------------------------------------------------------
insert支持的协议：
SMS_ALL
SMS_INBOX
SMS_FAILED
SMS_QUEUED
SMS_SENT
SMS_DRAFT
SMS_OUTBOX
SMS_RAW_MESSAGE
SMS_STATUS_PENDING
SMS_ATTACHMENT
SMS_NEW_THREAD_ID
向sms表插入数据时，type是根据协议来自动设置，
如果传入的数据中没有设置date时，自动设置为当前系统时间；非SMS_INBOX协议时，read标志设置为1
SMS_INBOX协议时，系统会自动查询并设置PERSON
threadId为null或者0时，系统也会自动设置
一直为造不了"发送失败"的邮件而发愁，现在来做一个：
content://sms/failed
ContentValues cv = new ContentValues();
cv.put("_id", "99");
cv.put("thread_id", "0");
cv.put("address", "9999");
cv.put("person", "888");
cv.put("date", "9999");
cv.put("protocol", "0");
cv.put("read", "1");
cv.put("status", "-1");
//cv.put("type", "0");
cv.put("body", "@@@@@@@@@");
this.getContentResolver().insert(Uri.parse("content://sms/failed"), cv);
type被设置成了5，thread_id设置为1
彩信。
1、pdu表
mmssms.db库中的pdu表存储了彩信标题、彩信接收时间和彩信ID等信息，其中“_id”是主键，唯一标识了一个条彩信。

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。
