彩信下载

發布時間：2023/11/27 生活经验 28 豆豆

生活随笔收集整理的這篇文章主要介紹了彩信下载小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

PduPersister.java loadParts 在發送mms前，會調用，就是將數據庫表中的數據轉成pdu用于發送；接收彩信時，也要調用。
據觀察，接收后，數據庫已經不正常。
設成不自動下載，僅收通知，查看log 發現沒有調用loadParts
點擊下載，調用loadParts
照最直觀的想法，應該是普通數據，準備發送時，轉成pdu，然后發送，收到pdu，轉成普通數據，存儲。讀取的時候直接讀取普通數據。
那么，這里下載時，為什么需要loadParts，這應該是創建pdu的過程啊？
仔細查看調用loadParts的loadFromDB，在PduHeaders.MESSAGE_TYPE_RETRIEVE_CONF和PduHeaders.MESSAGE_TYPE_SEND_REQ時，調用loadParts(msgId);
從log可以看到，無論發送，接收，下載彩信，都會調用loadFromDB，但是，數據都是用SqliteWrapper.query取出來的。
發送好理解，創建彩信時已經保存了，接收呢？在loadFromDB前已經存入數據庫了？
看接收流程：
SMSDispatcher.java handleMessage(Message msg){ EVENT_NEW_SMS: 調用CdmaSMSDispatcher.java 的dispatchMessage(SmsMessageBase smsb){
sms = (SmsMessage)smsb; sms.parseSms();teleService = sms.getTeleService(); teleService為SmsEnvelope.TELESERVICE_WAP就調用processCdmaWapPdu(sms, sms.messageRef, sms.getOrginationAddress()); 看log得知，這時，是接收不下載的流程。

知識小點：public abstract void sendOrderedBroadcast(Intent intent,String receiverPermission, BroadcastReceiver resultReceiver,Handler scheduler, int initialCode, String initialData,Bundle initialExtras);
這個廣播中receiverPermission設置后，只有這些權限的才能接收。

彩信接收不下載，存入pdu表，下載后，將彩信文字內容插入words

每次打開彩信，都會調用PduPersister load pdu use content type:
下載：RetrieveTransaction( ?550): RetrieveTransaction download from URL:http://10.234.45.180:80/... result pdu is:.... ...

下載：
NotificationTransaction.java
run()
byte[] retrieveConfData = getPdu(mContentLocation) ->  HttpUtils.httpConnection(...) 下載數據
GenericPdu pdu = new PduParser(retrieveConfData).parse(mPhoneId);

NotificationTraction run() -> PduPersister p; p.persist(pdu, Inbox.CONTENT_URI,mPhoneId) -> persistPart 

PduPersister.java persistPart(PduPart part, long msgId) 將part中的Part.CHARSET Part.CONTENT_TYPE Part.FILENAME Part.NAME 等等取出來，存到指定的uri下面。


收彩信過程中，哪里觸發連接網絡？ cmwap or ctwap
TransactionService.java
protected int beginMmsConnectivity() throws IOException{

}
ConnectivityService.java
public int startUsingNetworkFeature(int networkType, String feature, IBinder binder){
}

GsmDataConnectionTracker.java 是一開機就創建的么？因為有創建sTracker = MpdpMsmsGsmDataConnectionTracker[PhoneFactory.getSimCount()];的動作

即會根據是否支持mpdp而創建，在onEnableNewApn時調用onEnableNewApnInternal()要根據sTracker中的對象類型，決定是否調用mpdp相關的函數。

MpdpMsmsGsmDataConnectionTracker.java

public void onEnableNewApnInternal(){

Log.i("GSM","***********************try to setup new pdp Connection");

trySetupData(reason);

}

如果當前是cmnet連接，則要創建cmwap連接。

protected boolean setupData(String reason){

? pdp = findFreePdp();

? pdp.connect(msg, apn);

? mActivePdp = pdp;

}

GsmDataConnection.java

protected void onConnect(ConnectionParams cp){

phone.mCM.setupDataCall(...);

}
