Uicc之UiccCardApplication(原)

        UiccCardApplication所担任的任务主要包括创建并向外提供IccFileHandler、IccRecords对象、提供对SIM卡状态的监听等。


一、UiccCardApplication的主要功能


        我们从UiccCardApplication提供的public方法来查看其提供的主要功能。
        public void registerForReady(Handler h, int what, Object obj) {}
        public void registerForLocked(Handler h, int what, Object obj) {}
        public void registerForNetworkLocked(Handler h, int what, Object obj) {}
        public AppState getState() {}
        public AppType getType() {}
        public PersoSubState getPersoSubState() {}
        public String getAid() {}
        public PinState getPin1State() {}
        public IccFileHandler getIccFileHandler() {}
        public IccRecords getIccRecords() {}
        public void supplyPin (String pin, Message onComplete) {}
        public void supplyPuk (String puk, String newPin, Message onComplete) {}
        public void supplyPin2 (String pin2, Message onComplete) {}
        public void supplyPuk2 (String puk2, String newPin2, Message onComplete) {}
        public void supplyNetworkDepersonalization (String pin, Message onComplete) {}
        public boolean getIccLockEnabled() {}
        public boolean getIccFdnEnabled() {}
        public void setIccLockEnabled (boolean enabled, String password, Message onComplete) {}
        public void setIccFdnEnabled (boolean enabled, String password, Message onComplete) {}
        public void changeIccLockPassword(String oldPassword, String newPassword, Message onComplete) {}
        public void changeIccFdnPassword(String oldPassword, String newPassword, Message onComplete) {}
        由此可以看到UiccCardApplication的主要功能:
        1、创建并向外提供IccFileHandler、IccRecords对象
        2、查询当前UiccCardApplication状态信息,主要包括mAppState、mAppType
        3、查询、设置Fdn的状态
        4、查询、设置Pin、Puk状态和密码

        5、提供网络锁、Pin锁、状态OK的监听器


二、UiccCardApplication的初始化过程


        在介绍UiccCard时我们分析到, UiccCard更新时就会创建或者更新UiccCardApplication对象
        我们先来看UiccCardApplication的属性:
        public class UiccCardApplication {}
        与UiccCard类似,其没有父类,然后看构造函数:
        UiccCardApplication(UiccCard uiccCard, IccCardApplicationStatus as, Context c, CommandsInterface ci) {
            mUiccCard = uiccCard;
            mAppState = as.app_state;
            mAppType = as.app_type;
            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;

            //创建IccFileHandler对象
            mIccFh = createIccFileHandler(as.app_type);
            //创建IccRecords对象
            mIccRecords = createIccRecords(as.app_type, mContext, mCi);
            if (mAppState == AppState.APPSTATE_READY) {
                //查询fdn号码
                queryFdn();
                //查询Pin码状态
                queryPin1State();
            }
        }
        在构造函数中主要完成了四个任务:
        1、创建SIM卡的文件系统管理者IccFileHandler的子类对象:SIMFileHandler/RuimFileHandler/UsimFileHandler/CsimFileHandler/IsimFileHandler
        2、创建SIM卡信息IccRecords的子类对象:SIMRecords/RuimRecords/IsimUiccRecords
        3、查询Fdn号码

        4、查询Pin码状态


三、UiccCardApplication的更新过程


        当Modem的SIM卡或者Radio状态改变时,就会通过UiccController更新UiccCard,然后再由UiccCard更新UiccCardApplication,此时就会调用update()方法:
    void update (IccCardApplicationStatus as, Context c, CommandsInterface ci) {
        synchronized (mLock) {
            //状态更新
            mContext = c;
            mCi = ci;
            AppType oldAppType = mAppType;
            AppState oldAppState = mAppState;
            PersoSubState oldPersoSubState = mPersoSubState;
            mAppType = as.app_type;
            mAppState = as.app_state;
            mPersoSubState = as.perso_substate;
            mAid = as.aid;
            mAppLabel = as.app_label;
            mPin1Replaced = (as.pin1_replaced != 0);
            mPin1State = as.pin1;
            mPin2State = as.pin2;

            if (mAppType != oldAppType) {
                if (mIccFh != null) { mIccFh.dispose();}
                if (mIccRecords != null) { mIccRecords.dispose();}
                //重新创建IccFileHandler和IccRecords
                mIccFh = createIccFileHandler(as.app_type);
                mIccRecords = createIccRecords(as.app_type, c, ci);
            }

            if (mPersoSubState != oldPersoSubState && mPersoSubState == PersoSubState.PERSOSUBSTATE_SIM_NETWORK) {
                //通知网络锁的监听器
                notifyNetworkLockedRegistrantsIfNeeded(null);
            }

            if (mAppState != oldAppState) {
                if (mAppState == AppState.APPSTATE_READY) {
                    //重新查询Fdn和Pin
                    queryFdn();
                    queryPin1State();
                }
                //通知网络锁和网络注册的监听器
                notifyPinLockedRegistrantsIfNeeded(null);
                notifyReadyRegistrantsIfNeeded(null);
            }
        }
    }
        我们看到,在UiccCardApplication的更新过程中,完成了3个任务:
        1、更新当前状态相关的成员变量
        2、需要时重新构建IccFileHandler、IccRecords,以及重新查询Fdn和Pin
        3、通知监听器

        接下来的章节我们分析由UiccCardApplication创建的 IccFileHandler和IccRecords对象
