一段完整的Android平臺上短信功能的接口源碼，利用擴展的API可以通過js實現如下功能：

1. getContentUris()：讀取短信相關的所有數據庫表的Uri地址；
2. get(int number)：讀取若干條短信；
3. getUnread(int number)：讀取若干條未讀短信；
4. getRead(int number)：讀取若干條已讀短信；
5. getInbox(int number)：從收件箱讀取若干條短信；
6. getSent(int number)：讀取若干條已發短信；
7. getByThread(int threadID)：讀取會話中所有短信；
8. getThreads(int number)：讀取若干條會話；
9. getData(String selection, int number)：根據條件讀取若干條短信。
