Sim卡初始化
启动过程中初始化 SIM卡的一些相关数据
主要的类及其作用：
| 类名 | 描述 |
| PhoneGlobals | 里面的OnCreate直接调用了 PhoneFactory.makeDefaultPhones(this); |
| PhoneApp | TelephonyServer 入口里面初始化了两个对象一个是PhoneGlobals TelephonyGlobals |
| UiccController | 整个Uicc相关信息的控制接口，监控SIM状态变化 |
| UiccCard | Uicc卡的抽象，用来更新卡的状态 |
| IccCardStatus | 维护Uicc卡的状态，CardState&PinState |
| UiccCardApplication | Uicc的一个具体的应用，负责卡中数据读写，存取，pin和puk密码设置，解锁 |
| CatService | 主要负责SIM Tollkit相关 |
| IccConstants | SIM卡中文件地址，不同数据在SIM卡上的字段地址。 |
| IccRecords | 记录SIM卡的数据 |
| IccFileHandler | 读取SIM卡数据以及处理接收的结果。 |

UiccController.make(context, sCommandsInterfaces)开始初始化UiccController
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之间建立关系，这样的话，当SIM卡发送变化时UiccContrller就可以马上知道并且做出相应的操作。
UiccController对象是在PhoneFactory中makeDefaultPhone()方法中初始化的，有个细节有个细节值得注意的是sCommandsInterfaces数组的i对应的是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("UiccController.make() should only be called once");}//实例化UiccController对象mInstance = new UiccController(c, ci);return mInstance;}}private UiccController(Context c, CommandsInterface []ci) {if (DBG) log("Creating UiccController");Log.v("InitSimCartId","初始化 UiccContrort....");mContext = c;mCis = ci;if (DBG) {String logStr = "config_num_physical_slots = " + c.getResources().getInteger(com.android.internal.R.integer.config_num_physical_slots);log(logStr);sLocalLog.log(logStr);}int numPhysicalSlots = c.getResources().getInteger(com.android.internal.R.integer.config_num_physical_slots);// Minimum number of physical slot count should be equals to or greater than phone count,// if it is less than phone count use phone count as physical slot count.if (numPhysicalSlots < mCis.length) {numPhysicalSlots = mCis.length;}mUiccSlots = new UiccSlot[numPhysicalSlots];mPhoneIdToSlotId = new int[ci.length];Arrays.fill(mPhoneIdToSlotId, INVALID_SLOT_ID);if (VDBG) logPhoneIdToSlotIdMapping();mRadioConfig = RadioConfig.getInstance(mContext);mRadioConfig.registerForSimSlotStatusChanged(this, EVENT_SLOT_STATUS_CHANGED, null);Log.v("InitSimCartId","mCis 事件注册.......");for (int i = 0; i < mCis.length; i++) {// i对应的是PhoneId//注册监听四种事件 mCis 就是RIL//对ICC状态的任何更改触发mCis[i].registerForIccStatusChanged(this, EVENT_ICC_STATUS_CHANGED, i);//EVENT_ICC_STATUS_CHANGED监听SIM卡的状态变化//启动任何过渡!RadioState.isAvailable()mCis[i].registerForAvailable(this, EVENT_RADIO_AVAILABLE, i);//在任何转换时触发RADIO_OFF or !RadioState.isAvailable()mCis[i].registerForNotAvailable(this, EVENT_RADIO_UNAVAILABLE, i);//EVENT_RADIO_UNAVAILABLE（一旦radio变成不可用状态，就清空SIM卡的信息）//设置SIM刷新通知的处理程序。mCis[i].registerForIccRefresh(this, EVENT_SIM_REFRESH, i);}mLauncher = new UiccStateChangedLauncher(c, this);}在上面UiccController的构造方法中可以看到，注册了四个事件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。

仔细看UiccController初始化UiccSlot的时候就会发现最后调用的是 mUiccSlots[i].update(isActive ? mCis[iss.logicalSlotIndex] : null, iss);方法 update方法，看代码说话 ！ 在里面初始化了UiccCard

在UiccCard的构造方法中，最终还是调用了update()方法 里面初始化了UiccProfile

6.UiccCardApplication.java 全路径：android\frameworks\opt\telephony\src\java\com\android\internal\telephony\uicc\UiccCardApplication.java
最有用的就是mIccRecords = createIccRecords(as.app_type, mContext, mCi);//根据AppType创建对应的IccRecords 对象
创建了IccRecords对象里面开启一些注册

7.SIMRecords.java 全路径：android\frameworks\opt\telephony\src\java\com\android\internal\telephony\uicc\SIMRecords.java
对象实例化:
第一步是看 mParentApp.registerForReady(this, EVENT_APP_READY, null);注册监听，如果已ready然后进入SIMRecords里面的handlerMessage对应的case EVENT_APP_READY:里面调用了，onReady();方法
public SIMRecords(UiccCardApplication app, Context c, CommandsInterface ci) {super(app, c, ci);mAdnCache = new AdnRecordCache(mFh);mVmConfig = new VoiceMailConstants();mRecordsRequested = false; // No load request is made till SIM readymLockedRecordsReqReason = LOCKED_RECORDS_REQ_REASON_NONE;// recordsToLoad is set to 0 because no requests are made yetmRecordsToLoad = 0;mCi.setOnSmsOnSim(this, EVENT_SMS_ON_SIM, null);//初始化成员变量// Start off by setting empty stateresetRecords();//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);mParentApp.registerForNetworkLocked(this, EVENT_APP_NETWORK_LOCKED, null);if (DBG) log("SIMRecords X ctor this=" + this);}@Overridepublic void onReady() {fetchSimRecords();}
当执行到fetchSimRecords()方法时，才是开始加载EF文件信息
==============================EF相关文件介绍：===========================
SIM卡里的所有文件按树来组织:
主文件MF(Master File)——每一块SIM卡只有一个唯一的主文件, 其他所有文件都是它的子孙, 主文件只有文件头,里面存放着整个SIM卡的控制和管理信息
专用文件DF(Dedicated File)——也是只有一个文件头, 里面存放着整个目录的管理控制信息, 专用文件相当于一个目录的根.
基本文件EF(Elementary File)——既有文件头,也有文件体, 文件头存放该文件的位置和控制信息, 文件体存放真正的数据, 整个SIM卡中只有基本文件有文件体, 也只有基本文件才用来存放数据.。EF就是作手机通讯存储作用的文件。
=========================================================================
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laodEFLinearFixed()最终会调用RIL。java的 iccOForApp();

这个类是SIMRecords类中fetchSimRecords()方法里面的mFh对应的对象 ，该类属于Handler

读ICCID，SPDI，VoiceMail，SPN，PNN
回到fetcheSimRecords()方法，每加载一项，mRecordsToload就会加1；等到某一项数据读取数据完毕，handleMessage()方法被执行，就会调onRecordLoaded()方法
