Android彩信发送介绍?? 这篇写彩信发送过程。 我想追踪的内容是：用户按下发送之后，彩信的图片阿数据阿文件阿，是怎么包装起来，最后发送出去。 按我看源码的先后顺序来写了。 写完可能最后整理下。 1. com.Android.mms.data.WorkingMessage.Java 类 send()函数。 注释如下： ??? /** ???? * Send this message over the network. Will call back with onMessageSent() ???? * once it has been dispatched to the telephony stack. This WorkingMessage ???? * object is no longer useful after this method has been called. ???? */ 这个是2.1的源码 Java代码 复制到剪贴板??Java代码 public?void?send()?{?? ?? ????if?(Log.isLoggable(LogTag.TRANSACTION,?Log.VERBOSE))?{?? ?? ????????LogTag.debug(send);?? ?? ????}?? ?? ?? ?? ????//?Get?ready?to?write?to?disk.?? ?? ????prepareForSave(true?/*?notify?*/);?? ?? ?? ?? ????//?We?need?the?recipient?list?for?both?SMS?and?MMS.?? ?? ????final?Conversation?conv?=?mConversation;?? ?? ????String?msgTxt?=?mText.toString();?? ?? ?? ?? ????if?(requiresMms()?||?addressContainsEmailToMms(conv,?msgTxt))?{?? ?? ????????//?Make?local?copies?of?the?bits?we?need?for?sending?a?message,?? ?? ????????//?because?we?will?be?doing?it?off?of?the?main?thread,?which?will?? ?? ????????//?immediately?continue?on?to?resetting?some?of?this?state.?? ?? ????????final?Uri?mmsUri?=?mMessageUri;?? ?? ????????final?PduPersister?persister?=?PduPersister?? ?? ????????????????.getPduPersister(mContext);?? ?? ?? ?? ????????final?SlideshowModel?slideshow?=?mSlideshow;?? ?? ????????final?SendReq?sendReq?=?makeSendReq(conv,?mSubject);?? ?? ?? ?? ????????//?Make?sure?the?text?in?slide?0?is?no?longer?holding?onto?a?? ?? ????????//?reference?to?the?text?? ?? ????????//?in?the?message?text?box.?? ?? ????????slideshow.prepareForSend();?? ?? ?? ?? ????????//?Do?the?dirty?work?of?sending?the?message?off?of?the?main?UI?? ?? ????????//?thread.?? ?? ????????new?Thread(new?Runnable()?{?? ?? ????????????public?void?run()?{?? ?? ????????????????sendMmsWorker(conv,?mmsUri,?persister,?slideshow,?sendReq);?? ?? ????????????}?? ?? ????????}).start();?? ?? ????}?else?{?? ?? ????????//?Same?rules?apply?as?above.?? ?? ?????
