Android短信功能实现源码

一段完整的Android平台上短信功能的接口源码，利用扩展的API可以通过js实现如下功能：

1. getContentUris()：读取短信相关的所有数据库表的Uri地址；
2. get(int number)：读取若干条短信；
3. getUnread(int number)：读取若干条未读短信；
4. getRead(int number)：读取若干条已读短信；
5. getInbox(int number)：从收件箱读取若干条短信；
6. getSent(int number)：读取若干条已发短信；
7. getByThread(int threadID)：读取会话中所有短信；
8. getThreads(int number)：读取若干条会话；
9. getData(String selection, int number)：根据条件读取若干条短信。
