本文讲解SIMRecords
/frameworks/opt/telephony/src/java/com/android/internal/telephony/uicc/SIMRecords.java
构造方法：
public SIMRecords(UiccCardApplication app, Context c, CommandsInterface ci) { super(app, c, ci); mAdnCache = new AdnRecordCache(mFh); mVmConfig = new VoiceMailConstants(); mSpnOverride = new SpnOverride(); mCi.setOnSmsOnSim(this, EVENT_SMS_ON_SIM, null);//消息注册，当Ci接收到EVENT_SMS_ON_SIM消息通知SIMRecords mCi.registerForIccRefresh(this, EVENT_SIM_REFRESH, null); // Start off by setting empty state resetRecords(); mParentApp.registerForReady(this, EVENT_APP_READY, null);//当卡准备好，UiccCardApplication会通过notifyReadyRegistrantsifNeeded()通知SIMRecords mParentApp.registerForLocked(this, EVENT_APP_LOCKED, null);//EVENT_APP_LOCKED消息同样处理 if (DBG) log("SIMRecords X ctor this=" + this); IntentFilter intentfilter = new IntentFilter(); intentfilter.addAction(CarrierConfigManager.ACTION_CARRIER_CONFIG_CHANGED); c.registerReceiver(mReceiver, intentfilter); //接收ACTION_CARRIER_CONFIG_CHANGED消息的处理 }
接收UiccCardApplication 的通知，消息EVENT_APP_READY、EVENT_APP_LOCKED 的处理：
try { switch (msg.what) { case EVENT_APP_READY: onReady(); break; case EVENT_APP_LOCKED: onLocked(); break; }
onReady() 方法，直接调用fetchSimRecords()，到这里开始加载EF文件信息:
具体的读取SIM卡EF文件信息的过程是有IccFileHandler来实现的，根据EF文件的类型，调用不同的方法loadEFTransparent()和loadEFLinearFixed()，最终都会调用RILJ 的iccIOForApp() 方法；
protected void fetchSimRecords() { if (DBG) log("fetchSimRecords " + mRecordsToLoad); mCi.getIMSIForApp(mParentApp.getAid(), obtainMessage(EVENT_GET_IMSI_DONE));//获取IMSI信息，返回的数据在该类handleMessage()中处理 mRecordsToLoad++; //没读取一项信息，计数值就加1 mFh.loadEFTransparent(EF_ICCID, obtainMessage(EVENT_GET_ICCID_DONE));//获取ICCID mRecordsToLoad++; // Same goes for Call Forward Status indicator: fetch both // EF[CFIS] and CPHS-EF, with EF[CFIS] preferred. loadCallForwardingRecords(); getSpnFsm(true, null); loadEfLiAndEfPl(); if (CRASH_RIL) { String sms = "0107912160130310f20404d0110041007030208054832b0120" + "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" + "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" + "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" + "fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff" + "ffffffffffffffffffffffffffffff"; byte[] ba = IccUtils.hexStringToBytes(sms); mFh.updateEFLinearFixed(EF_SMS, 1, ba, null, obtainMessage(EVENT_MARK_SMS_READ_DONE, 1)); } if (DBG) log("fetchSimRecords " + mRecordsToLoad + " requested: " + mRecordsRequested); }
