本文主要讲述Android 6.0 SIM卡初始化流程，这个过程也涉及到UICC框架的初始化，UICC(Universal Integrated Circuit Card)的架构图如下：
/**
* This class is responsible for keeping all knowledge about
* Universal Integrated Circuit Card (UICC), also know as SIM‘s,
* in the system. It is also used as API to get appropriate
* applications to pass them to phone and service trackers.
*
* UiccController is created with the call to make() function.
* UiccController is a singleton and make() must only be called once
* and throws an exception if called multiple times.
*
* Once created UiccController registers with RIL for "on" and "unsol_sim_status_changed"
* notifications. When such notification arrives UiccController will call
* getIccCardStatus (GET_SIM_STATUS). Based on the response of GET_SIM_STATUS
* request appropriate tree of uicc objects will be created.
*
* Following is class diagram for uicc classes:
*
* UiccController
* #

* UiccCard
* # #
* | ------------------
* UiccCardApplication CatService

* and {@link com.android.internal.telephony.uicc.IccCardProxy}
*/
UiccController是整个UICC相关信息的控制接口，UiccController的实例化就是在RIL与UiccController 之间建立监听关系，这样的话，当SIM卡状态发生变化时，UiccController就可以马上知道并且做出相应的操作。
UiccController对象是在PhoneFacotry.java中的makeDefaultPhone()方法中初始化的，有个细节值得注意的是sCommandsInterfaces数组的i对应的是PhoneId。
public static void makeDefaultPhone(Context context) {
// Instantiate UiccController so that all other classes can just
// call getInstance()
mUiccController = UiccController.make(context, sCommandsInterfaces);
for (int i = 0; i < numPhones; i++) {
PhoneBase phone = null;
int phoneType = TelephonyManager.getPhoneType(networkModes[i]);
if (phoneType == PhoneConstants.PHONE_TYPE_GSM) {
//sCommandsInterfaces的i对应的是PhoneId
phone = TelephonyPluginDelegate.getInstance().makeGSMPhone(context,
sCommandsInterfaces[i], sPhoneNotifier, i);
} else if (phoneType == PhoneConstants.PHONE_TYPE_CDMA) {
phone = TelephonyPluginDelegate.getInstance().makeCDMALTEPhone(context,
sCommandsInterfaces[i], sPhoneNotifier, i);
}
Rlog.i(LOG_TAG, "Creating Phone with type = " + phoneType + " sub = " + i);
sProxyPhones[i] = TelephonyPluginDelegate.getInstance().makePhoneProxy(phone);
}
}
@TelephonyPluginBase.java
public PhoneBase makeGSMPhone(Context context, CommandsInterface ci,
PhoneNotifier notifier, int phoneId) {
return new GSMPhone(context, ci, notifier, phoneId);
}
}在UiccController.java的make()方法中new了一个UiccController对象，
public static UiccController make(Context c, CommandsInterface[] ci) {
synchronized (mLock) {
if (mInstance != null) {
throw new RuntimeException("MSimUiccController.make() should only be called once");
}
mInstance = new UiccController(c, ci);
return (UiccController)mInstance;
}
}
private UiccController(Context c, CommandsInterface []ci) {
if (DBG) log("Creating UiccController");
mContext = c;
mCis = ci;
for (int i = 0; i < mCis.length; i++) {
Integer index = new Integer(i);
mCis[i].registerForIccStatusChanged(this, EVENT_ICC_STATUS_CHANGED, index);
mCis[i].registerForAvailable(this, EVENT_ICC_STATUS_CHANGED, index);
mCis[i].registerForNotAvailable(this, EVENT_RADIO_UNAVAILABLE, index);
mCis[i].registerForIccRefresh(this, EVENT_SIM_REFRESH, index);
}
}在上面UiccController的构造方法中可以看到，注册了三个事件EVENT_ICC_STATUS_CHANGED（监听SIM卡的状态变化），EVENT_RADIO_UNAVAILABLE（一旦radio变成不可用状态，就清空SIM卡的信息），EVENT_SIM_REFRESH。index对应的是PhoneId，当上面这三种消息上来时，就知道对应哪个Phone对象，也就对应那张卡。
当接收到EVENT_ICC_STATUS_CHANGED消息后，UiccController调用RIL.java的getIccCardStatus()方法给MODEM发送RIL_REQUEST_GET_SIM_STATUS消息，查询SIM卡的状态。
public void handleMessage (Message msg) {
.....
//首先从Message中取出PhoneId
Integer index = getCiIndex(msg);
.....
case EVENT_ICC_STATUS_CHANGED:
if (DBG) log("Received EVENT_ICC_STATUS_CHANGED, calling getIccCardStatus");
//查询当前SIM卡的状态
mCis[index].getIccCardStatus(obtainMessage(EVENT_GET_ICC_STATUS_DONE, index));
break;
case EVENT_GET_ICC_STATUS_DONE:
if (DBG) log("Received EVENT_GET_ICC_STATUS_DONE");
onGetIccCardStatusDone(ar, index);
break;
}
当查询SIM卡的状态完毕后，先从result中解析出IccCardStatus，依据IccCardStatus来创建UiccCard对象，一个UiccCard 对象代表着一张SIM卡；如果UiccCard对象已存在就直接调它的update()方法更新UiccCard的信息。
private synchronized void onGetIccCardStatusDone(AsyncResult ar, Integer index) {
if (ar.exception != null) {
Rlog.e(LOG_TAG,"Error getting ICC status. "
+ "RIL_REQUEST_GET_ICC_STATUS should "
+ "never return an error", ar.exception);
return;
}
if (!isValidCardIndex(index)) {
Rlog.e(LOG_TAG,"onGetIccCardStatusDone: invalid index : " + index);
return;
}
IccCardStatus status = (IccCardStatus)ar.result;
//1.创建或更新UiccCard
if (mUiccCards[index] == null) {
//Create new card（Android6.0 调的是4个参数的构造方法）
mUiccCards[index] = new UiccCard(mContext, mCis[index], status, index);
} else {
//Update already existing card
mUiccCards[index].update(mContext, mCis[index] , status);
}
if (DBG) log("Notifying IccChangedRegistrants");
//2.通知监听UiccController的监听者
mIccChangedRegistrants.notifyRegistrants(new AsyncResult(null, index, null));
}在UiccCard的构造方法中，最终还是调用了update()方法
public UiccCard(Context c, CommandsInterface ci, IccCardStatus ics, int phoneId) {
mCardState = ics.mCardState;
mPhoneId = phoneId;
update(c, ci, ics);
}
public void update(Context c, CommandsInterface ci, IccCardStatus ics) {
synchronized (mLock) {
CardState oldState = mCardState;
mCardState = ics.mCardState;
mUniversalPinState = ics.mUniversalPinState;
mGsmUmtsSubscriptionAppIndex = ics.mGsmUmtsSubscriptionAppIndex;
mCdmaSubscriptionAppIndex = ics.mCdmaSubscriptionAppIndex;
mImsSubscriptionAppIndex = ics.mImsSubscriptionAppIndex;
mContext = c;
mCi = ci;
//update applications
if (DBG) log(ics.mApplications.length + " applications");
for ( int i = 0; i < mUiccApplications.length; i++) {
if (mUiccApplications[i] == null) {
//Create newly added Applications
if (i < ics.mApplications.length) {
mUiccApplications[i] = new UiccCardApplication(this,
ics.mApplications[i], mContext, mCi);
}
} else if (i >= ics.mApplications.length) {
//Delete removed applications
mUiccApplications[i].dispose();
mUiccApplications[i] = null;
} else {
//Update the rest
mUiccApplications[i].update(ics.mApplications[i], mContext, mCi);
}
}
//创建CatService,用于读取STK的信息
createAndUpdateCatService();
// Reload the carrier privilege rules if necessary.
log("Before privilege rules: " + mCarrierPrivilegeRules + " : " + mCardState);
if (mCarrierPrivilegeRules == null && mCardState == CardState.CARDSTATE_PRESENT) {
mCarrierPrivilegeRules = new UiccCarrierPrivilegeRules(this,
mHandler.obtainMessage(EVENT_CARRIER_PRIVILIGES_LOADED));
} else if (mCarrierPrivilegeRules != null && mCardState != CardState.CARDSTATE_PRESENT) {
mCarrierPrivilegeRules = null;
}
sanitizeApplicationIndexes();
RadioState radioState = mCi.getRadioState();
if (DBG) log("update: radioState=" + radioState + " mLastRadioState="
+ mLastRadioState);
// No notifications while radio is off or we just powering up
if (radioState == RadioState.RADIO_ON && mLastRadioState == RadioState.RADIO_ON) {
if (oldState != CardState.CARDSTATE_ABSENT &&
mCardState == CardState.CARDSTATE_ABSENT) {
if (DBG) log("update: notify card removed");
mAbsentRegistrants.notifyRegistrants();
mHandler.sendMessage(mHandler.obtainMessage(EVENT_CARD_REMOVED, null));
} else if (oldState == CardState.CARDSTATE_ABSENT &&
mCardState != CardState.CARDSTATE_ABSENT) {
if (DBG) log("update: notify card added");
mHandler.sendMessage(mHandler.obtainMessage(EVENT_CARD_ADDED, null));
}
}
mLastRadioState = radioState;
}
}在UiccCard.java的update()方法中，实例化了UiccCardApplication对象，或者调UiccCardApplication的update()方法更新状态。mCardState记录着卡的状态，根据新旧mCardState就可以知道CARD_ADDED或者CARD_REMOVED。
UiccCardApplication(UiccCard uiccCard,
IccCardApplicationStatus as,
Context c,
CommandsInterface ci) {
if (DBG) log("Creating UiccApp: " + as);
mUiccCard = uiccCard;
mAppState = as.app_state;
mAppType = as.app_type;
mAuthContext = getAuthContext(mAppType);
mPersoSubState = as.perso_substate;
mAid = as.aid;
mAppLabel = as.app_label;
mPin1Replaced = (as.pin1_replaced != 0);
mPin1State = as.pin1;
mPin2State = as.pin2;
mContext = c;
mCi = ci;
//根据AppType实例化IccFileHandler
mIccFh = createIccFileHandler(as.app_type);
//根据AppType实例化IccRecords
mIccRecords = createIccRecords(as.app_type, mContext, mCi);
if (mAppState == AppState.APPSTATE_READY) {
queryFdn();
//查询PIN1码的状态
queryPin1State();
}
mCi.registerForNotAvailable(mHandler, EVENT_RADIO_UNAVAILABLE, null);
}在UiccCardApplication初始化的时候，会调用自身的createIccRecords()方法，根据AppType创建对应的IccRecords 对象。
private IccRecords createIccRecords(AppType type, Context c, CommandsInterface ci) {
if (type == AppType.APPTYPE_USIM || type == AppType.APPTYPE_SIM) {
return TelephonyPluginDelegate.getInstance().makeSIMRecords(this, c, ci);
} else if (type == AppType.APPTYPE_RUIM || type == AppType.APPTYPE_CSIM){
return new RuimRecords(this, c, ci);
} else if (type == AppType.APPTYPE_ISIM) {
return new IsimUiccRecords(this, c, ci);
} else {
// Unknown app type (maybe detection is still in progress)
return null;
}
}接着会进入TelephonyPluginDelegate.java和TelephonyPluginBase.java的makeSIMRecords()方法
@TelephonyPluginDelegate.java
public SIMRecords makeSIMRecords (UiccCardApplication app, Context c, CommandsInterface ci) {
return sPlugin.makeSIMRecords (app, c, ci);
}
@TelephonyPluginBase.java
public SIMRecords makeSIMRecords (UiccCardApplication app, Context c, CommandsInterface ci) {
return new SIMRecords(app, c, ci);
}到这里就可以看到直接new 了一个SIMRecords对象。
public SIMRecords(UiccCardApplication app, Context c, CommandsInterface ci) {
super(app, c, ci);
mAdnCache = new AdnRecordCache(mFh);
mVmConfig = new VoiceMailConstants();
//从spn-conf.xml文件中加载SPN
mSpnOverride = new SpnOverride();
// No load request is made till SIM ready
mRecordsRequested = false;
// recordsToLoad is set to 0 because no requests are made yet
mRecordsToLoad = 0;
mCi.setOnSmsOnSim(this, EVENT_SMS_ON_SIM, null);
mCi.registerForIccRefresh(this, EVENT_SIM_REFRESH, null);
//初始化成员变量
resetRecords();
//注册监听，如果已ready，那么开始加载数据
mParentApp.registerForReady(this, EVENT_APP_READY, null);
mParentApp.registerForLocked(this, EVENT_APP_LOCKED, null);
if (DBG) log("SIMRecords X ctor this=" + this);
}等到AppState变成APPSTATE_READY是，UiccCardApplication会在notifyReadyRegistrantsIfNeeded()方法里通知SIMRecords，那么在SIMRecords的handleMessage()方法就会收到EVENT_APP_READY消息。
public void handleMessage(Message msg) {
case EVENT_APP_READY:
onReady();
break;
}
@Override
public void onReady() {
fetchSimRecords();
}当执行到fetchSimRecords()方法时，才真正开始加载EF文件信息。
具体的读取SIM卡EF文件信息的过程是由 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RIL.java的iccIOForApp()方法。
读取某一项信息时会调用两次RIL.java的iccIOForApp()：
第一次：先读取当前分区的长度lc.mRecordSize。
Message response = obtainMessage(EVENT_GET_RECORD_SIZE_DONE,
new LoadLinearFixedContext(fileid, recordNum, efPath, onLoaded));
mCi.iccIOForApp(COMMAND_GET_RESPONSE, fileid, efPath,
0, 0,
GET_RESPONSE_EF_SIZE_BYTES,
null, null, mAid, response);第二次：再根据lc.mRecordSize去读取具体内容。
case EVENT_GET_RECORD_SIZE_DONE:
......
mCi.iccIOForApp(COMMAND_READ_RECORD, lc.mEfid, path,
lc.mRecordNum,READ_RECORD_MODE_ABSOLUTE,
lc.mRecordSize,
null, null, mAid,obtainMessage(EVENT_READ_RECORD_DONE, lc));某一项信息的加载流程如下流程图。
protected void fetchSimRecords() {
mRecordsRequested = true;
if (DBG) log("fetchSimRecords " + mRecordsToLoad);
//读取IMSI
mCi.getIMSIForApp(mParentApp.getAid(), obtainMessage(EVENT_GET_IMSI_DONE));
mRecordsToLoad++;
//从EF_ICCID（0x2fe2）读取ICCID
mFh.loadEFTransparent(EF_ICCID, obtainMessage(EVENT_GET_ICCID_DONE));
mRecordsToLoad++;
// FIXME should examine EF[MSISDN]‘s capability configuration
// to determine which is the voice/data/fax line
new AdnRecordLoader(mFh).loadFromEF(EF_MSISDN, getExtFromEf(EF_MSISDN), 1,
obtainMessage(EVENT_GET_MSISDN_DONE));
mRecordsToLoad++;
//读取VoiceMail信息
mFh.loadEFLinearFixed(EF_MBI, 1, obtainMessage(EVENT_GET_MBI_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_AD, obtainMessage(EVENT_GET_AD_DONE));
mRecordsToLoad++;
// Record number is subscriber profile
mFh.loadEFLinearFixed(EF_MWIS, 1, obtainMessage(EVENT_GET_MWIS_DONE));
mRecordsToLoad++;
// Also load CPHS-style voice mail indicator, which stores
// the same info as EF[MWIS]. If both exist, both are updated
// but the EF[MWIS] data is preferred
// Please note this must be loaded after EF[MWIS]
mFh.loadEFTransparent(
EF_VOICE_MAIL_INDICATOR_CPHS,
obtainMessage(EVENT_GET_VOICE_MAIL_INDICATOR_CPHS_DONE));
mRecordsToLoad++;
// Same goes for Call Forward Status indicator: fetch both
// EF[CFIS] and CPHS-EF, with EF[CFIS] preferred.
loadCallForwardingRecords();
//从EF_SPN(0x6F46)、EF_SPN_CPHS(0x6f14)、EF_SPN_SHORT_CPHS(0x6f18)三个地址上读取SPN
getSpnFsm(true, null);
//从EF_SPDI（0x6fcd）读取SPDI
mFh.loadEFTransparent(EF_SPDI, obtainMessage(EVENT_GET_SPDI_DONE));
mRecordsToLoad++;
//从EF_PNN（0x6fc5）读取PNN
mFh.loadEFLinearFixed(EF_PNN, 1, obtainMessage(EVENT_GET_PNN_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_SST, obtainMessage(EVENT_GET_SST_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_INFO_CPHS, obtainMessage(EVENT_GET_INFO_CPHS_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_CSP_CPHS,obtainMessage(EVENT_GET_CSP_CPHS_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_GID1, obtainMessage(EVENT_GET_GID1_DONE));
mRecordsToLoad++;
mFh.loadEFTransparent(EF_GID2, obtainMessage(EVENT_GET_GID2_DONE));
mRecordsToLoad++;
loadEfLiAndEfPl();
// XXX should seek instead of examining them all
if (false) { // XXX
mFh.loadEFLinearFixedAll(EF_SMS, obtainMessage(EVENT_GET_ALL_SMS_DONE));
mRecordsToLoad++;
}
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);
}读取ICCID : ICCID通常有20位，根据TS 102.221，ICCID 是BCD编码的，只允许出现数字和字符F，如果出现其他字母，就会在下面IccUtils.bcdToString()方法中被截断。（如中国移动的SIM卡，会使用字符b代表188号段，那么应用层得到的ICCID就不是20位的了）
case EVENT_GET_ICCID_DONE:
isRecordLoadResponse = true;
ar = (AsyncResult)msg.obj;
data = (byte[])ar.result;
if (ar.exception != null) {
break;
}
mIccId = IccUtils.bcdToString(data, 0, data.length);
log("iccid: " + mIccId);
break;mIccId的值最后会通过IccRecords.java的getIccId()方法，提供给应用层使用。
public String getIccId() {
return mIccId;
}读取SPDI ： SPDI存储的是由numeric network ID组成的列表。
case EVENT_GET_SPDI_DONE:
isRecordLoadResponse = true;
ar = (AsyncResult)msg.obj;
data = (byte[])ar.result;
if (ar.exception != null) {
break;
}
parseEfSpdi(data);
break;
/**
* Parse TS 51.011 EF[SPDI] record
* This record contains the list of numeric network IDs that
* are treated specially when determining SPN display
*/
private void
parseEfSpdi(byte[] data) {
SimTlv tlv = new SimTlv(data, 0, data.length);
byte[] plmnEntries = null;
for ( ; tlv.isValidObject() ; tlv.nextObject()) {
// Skip SPDI tag, if existant
if (tlv.getTag() == TAG_SPDI) {
tlv = new SimTlv(tlv.getData(), 0, tlv.getData().length);
}
// There should only be one TAG_SPDI_PLMN_LIST
if (tlv.getTag() == TAG_SPDI_PLMN_LIST) {
plmnEntries = tlv.getData();
break;
}
}
if (plmnEntries == null) {
return;
}
mSpdiNetworks = new ArrayList<String>(plmnEntries.length / 3);
for (int i = 0 ; i + 2 < plmnEntries.length ; i += 3) {
String plmnCode;
plmnCode = IccUtils.bcdToString(plmnEntries, i, 3);
// Valid operator codes are 5 or 6 digits
if (plmnCode.length() >= 5) {
log("EF_SPDI network: " + plmnCode);
mSpdiNetworks.add(plmnCode);
}
}
}最终会把值存储到mSpdiNetworks这个列表中，mSpdiNetworks在判断PLMN和SPN显示规则时会使用到。
读取VoiceMail：后续写VoiceMail相关文章时会详细讲解。
读取SPN：后续写SPN相关文章时会详细讲解。
读取PNN：读取到PNN的值后，存储在mPnnHomeName中，但是mPnnHomeName并没有被其他地方调用。
case EVENT_GET_PNN_DONE:
isRecordLoadResponse = true;
ar = (AsyncResult)msg.obj;
data = (byte[])ar.result;
if (ar.exception != null) {
break;
}
SimTlv tlv = new SimTlv(data, 0, data.length);
for ( ; tlv.isValidObject() ; tlv.nextObject()) {
if (tlv.getTag() == TAG_FULL_NETWORK_NAME) {
mPnnHomeName
= IccUtils.networkNameToString(
tlv.getData(), 0, tlv.getData().length);
break;
}
}
break;可以自己新增代码，把mPnnHomeName通过setSystemProperty(key,value)方法存储到一个key里，然后在应用层就可以通过这个key，获取到PNN的值。
//存储mPnnHomeName的值
setSystemProperty(TelephonyProperties.PNN_NAME, mPnnHomeName);
//获取PNN的值
TelephonyManager.getTelephonyProperty(mPhone.getPhoneId(),
TelephonyProperties.PNN_NAME, "");回到fetchSimRecords()方法，每加载一项，mRecordsToLoad就加1；等到某一项读取数据完毕，handleMessage()方法被执行，就会调onRecordLoaded()方法
protected void onRecordLoaded() {
// One record loaded successfully or failed, In either case
// we need to update the recordsToLoad count
mRecordsToLoad -= 1;
if (DBG) log("onRecordLoaded " + mRecordsToLoad + " requested: " + mRecordsRequested);
if (mRecordsToLoad == 0 && mRecordsRequested == true) {
onAllRecordsLoaded();
} else if (mRecordsToLoad < 0) {
loge("recordsToLoad <0, programmer error suspected");
mRecordsToLoad = 0;
}
}mRecordsToLoad的值会减1，直到mRecordsToLoad的值为0时，说明在fetchSimRecords()中启动加载的数据都已异步读取完成。就会进入onAllRecordsLoaded()方法。
@Override
protected void onAllRecordsLoaded() {
if (DBG) log("record load complete");
Resources resource = Resources.getSystem();
if (resource.getBoolean(com.android.internal.R.bool.config_use_sim_language_file)) {
setSimLanguage(mEfLi, mEfPl);
} else {
if (DBG) log ("Not using EF LI/EF PL");
}
setVoiceCallForwardingFlagFromSimRecords();
if (mParentApp.getState() == AppState.APPSTATE_PIN ||
mParentApp.getState() == AppState.APPSTATE_PUK) {
// reset recordsRequested, since sim is not loaded really
mRecordsRequested = false;
// lock state, only update language
return ;
}
// Some fields require more than one SIM record to set
String operator = getOperatorNumeric();
if (!TextUtils.isEmpty(operator)) {
log("onAllRecordsLoaded set ‘gsm.sim.operator.numeric‘ to operator=‘" +
operator + "‘");
log("update icc_operator_numeric=" + operator);
mTelephonyManager.setSimOperatorNumericForPhone(
mParentApp.getPhoneId(), operator);
final SubscriptionController subController = SubscriptionController.getInstance();
subController.setMccMnc(operator, subController.getDefaultSmsSubId());
} else {
log("onAllRecordsLoaded empty ‘gsm.sim.operator.numeric‘ skipping");
}
if (!TextUtils.isEmpty(mImsi)) {
log("onAllRecordsLoaded set mcc imsi" + (VDBG ? ("=" + mImsi) : ""));
mTelephonyManager.setSimCountryIsoForPhone(
mParentApp.getPhoneId(), MccTable.countryCodeForMcc(
Integer.parseInt(mImsi.substring(0,3))));
} else {
log("onAllRecordsLoaded empty imsi skipping setting mcc");
}
setVoiceMailByCountry(operator);
setSpnFromConfig(operator);
mRecordsLoadedRegistrants.notifyRegistrants(
new AsyncResult(null, null, null));
}在onAllRecordsLoaded()方法中会对读取到的数据进行处理和存储，到这里，SIM卡初始化的流程就结束了。
