ADN加載流程

摘要：加載流程定義在從上面可以看到，真正的是在中繼承，處理的等操作，和卡交互完成后，將數(shù)據(jù)改變信息通知給然后將數(shù)據(jù)變化的發(fā)送給注冊(cè)監(jiān)聽(tīng)的應(yīng)用，應(yīng)用做相應(yīng)的同步動(dòng)作。

ADN加載流程：

IccProvider.java
IccProvider定義在/packages/services/Telephony/AndroidManifest.xml

  

public class IccProvider extends com.android.internal.telephony.IccProvider {
    public IccProvider() {
        super();
    }
}

從上面可以看到，真正的ICCProvider是在framework中繼承ContentProvider，處理ADN/FDN/SDN的query/insert/update/delete等操作，和SIM卡交互完成后，將數(shù)據(jù)改變信息通知給ContentObserver,然后ContentObserver將數(shù)據(jù)變化的發(fā)送給注冊(cè)監(jiān)聽(tīng)的應(yīng)用，Contacts應(yīng)用做相應(yīng)的同步動(dòng)作。
Contacts數(shù)據(jù)庫(kù)和SIM卡聯(lián)系的同步后面繼續(xù)分析。
關(guān)于ContentProvider和ContentResolver以及ContentObserver的介紹，可以參考：
http://blog.csdn.net/dmk877/a...

IccProvider重寫(xiě)ContentProvider的方法：

UiccPhoneBookController.java
UiccPhoneBookController在ProxyController的構(gòu)造方法中初始化。
mUiccPhoneBookController = new UiccPhoneBookController(mPhones);
UiccPhoneBookController的構(gòu)造方法：

public class UiccPhoneBookController extends IIccPhoneBook.Stub {
    private static final String TAG = "UiccPhoneBookController";
    private Phone[] mPhone;

    /* only one UiccPhoneBookController exists */
    public UiccPhoneBookController(Phone[] phone) {
        if (ServiceManager.getService("simphonebook") == null) {
               ServiceManager.addService("simphonebook", this);
        }
        mPhone = phone;

IccProvider通過(guò)AIDL調(diào)用UiccPhoneBookController：

try {
            IIccPhoneBook iccIpb = IIccPhoneBook.Stub.asInterface(
                    ServiceManager.getService("simphonebook"));
            if (iccIpb != null) {
                success = iccIpb.updateAdnRecordsInEfBySearchForSubscriber(subId, efType,
                        "", "", name, number, pin2);
            }
        } catch (RemoteException ex) {
            // ignore it
        } catch (SecurityException ex) {
            if (DBG) log(ex.toString());
        }

關(guān)于AIDL的實(shí)現(xiàn)后面詳細(xì)學(xué)習(xí)
IccPhoneBookInterfaceManager.java
IccPhoneBookInterfaceManager是在Phone的初始化時(shí)完成實(shí)例化:

在GsmCdmaPhone構(gòu)造方法initOnce()中：
 mIccPhoneBookIntManager = mTelephonyComponentFactory.makeIccPhoneBookInterfaceManager(this);

SimPhoneBookAdnRecordCache.java
SimPhoneBookAdnRecordCache在IccPhoneBookInterfaceManager構(gòu)造方法中完成初始化：
public IccPhoneBookInterfaceManager(Phone phone) {

    this.mPhone = phone;
    IccRecords r = phone.getIccRecords();

    if (r != null) {
        mAdnCache = r.getAdnCache();
    }

    if(isSimPhoneBookEnabled()){
        if(mSimPbAdnCache == null) {
            mSimPbAdnCache = new SimPhoneBookAdnRecordCache(
                    phone.getContext(), phone.getPhoneId(), phone.mCi);
        }
    }
}

    支持ADN/FDN/SDN的URL
private MatrixCursor loadFromEf(int efType, int subId) {
        if (DBG) log("loadFromEf: efType=0x" +
                Integer.toHexString(efType).toUpperCase() + ", subscription=" + subId);

        List adnRecords = null;
        try {
            IIccPhoneBook iccIpb = IIccPhoneBook.Stub.asInterface(
                    ServiceManager.getService("simphonebook"));
            if (iccIpb != null) {
                adnRecords = iccIpb.getAdnRecordsInEfForSubscriber(subId, efType);
            }
        } catch (RemoteException ex) {
            // ignore it
        } catch (SecurityException ex) {
            if (DBG) log(ex.toString());
        }
        //獲取adn list轉(zhuǎn)換成cursor
        if (adnRecords != null) {
            // Load the results
            final int N = adnRecords.size();
            final MatrixCursor cursor = new MatrixCursor(ADDRESS_BOOK_COLUMN_NAMES, N);
            if (DBG) log("adnRecords.size=" + N);
            for (int i = 0; i < N ; i++) {
                loadRecord(adnRecords.get(i), cursor, i);

UiccPhoneBookController時(shí)一個(gè)Binder服務(wù)類(lèi)，接口是IIccPhoneBook，服務(wù)名"simphonebook"

2.UiccPhoneBookController
getAdnRecordsInEfForSubscriber方法：

 @Override
    public List getAdnRecordsInEfForSubscriber(int subId, int efid)
           throws android.os.RemoteException {
           //獲取實(shí)例,實(shí)例在文章開(kāi)始Phone初始化時(shí)設(shè)置
        IccPhoneBookInterfaceManager iccPbkIntMgr =

        if (iccPbkIntMgr != null) {
        //調(diào)用getAdnRecordsInEf方法

            }
        }
        return mRecords;
    }

看看Handler的處理：
protected class IccPbHandler extends Handler {

    public IccPbHandler(Looper looper) {
        super(looper);
    }

    @Override
    public void handleMessage(Message msg) {
        AsyncResult ar;

        switch (msg.what) {
            case EVENT_GET_SIZE_DONE:
                ar = (AsyncResult) msg.obj;
                synchronized (mLock) {
                    if (ar.exception == null) {
                        mRecordSize = (int[])ar.result;
                        // recordSize[0]  is the record length
                        // recordSize[1]  is the total length of the EF file
                        // recordSize[2]  is the number of records in the EF file
                        logd("GET_RECORD_SIZE Size " + mRecordSize[0] +

                                " #record " + mRecordSize[2]);
                    }
                    notifyPending(ar);
                }
                break;
            case EVENT_UPDATE_DONE:
                ar = (AsyncResult) msg.obj;
                if(ar.exception != null) {
                    if(DBG) logd("exception of EVENT_UPDATE_DONE is" + ar.exception );
                }
                synchronized (mLock) {
                    mSuccess = (ar.exception == null);
                    notifyPending(ar);
                }
                break;
            case EVENT_LOAD_DONE://查詢(xún)完成
                ar = (AsyncResult)msg.obj;
                synchronized (mLock) {
                    if (ar.exception == null) {
                        if(DBG) logd("Load ADN records done");
                        //返回adn list
                        mRecords = (List) ar.result;
                    } else {

                        mRecords = null;
                    }
                    //notify()喚醒
                    notifyPending(ar);
                }
                break;
        }
    }

4.SimPhoneBookAdnRecordCache查詢(xún)，requestLoadAllAdnLike()方法

   public void requestLoadAllAdnLike(Message response) {
           //加入message list
            if (mAdnLoadingWaiters != null) {
                mAdnLoadingWaiters.add(response);
            }
            //線(xiàn)程同步
            synchronized (mLock) {
                if (!mSimPbRecords.isEmpty()) {
                    log("ADN cache has already filled in");
                    if (mRefreshAdnCache) {
                        mRefreshAdnCache = false;
                        refreshAdnCache();
                    } else {
                        notifyAndClearWaiters();
                    }
    
                    return;
            }
            //查詢(xún)adn
            queryAdnRecord();
        }
    }

queryAdnRecord方法：

public void queryAdnRecord () {

mRecCount = 0;
mAdnCount = 0;
mValidAdnCount = 0;
mEmailCount = 0;
mAddNumCount = 0;

log("start to queryAdnRecord");
//查詢(xún)ADN record,返回容量
mCi.getAdnRecord(obtainMessage(EVENT_QUERY_ADN_RECORD_DONE));
//向RIL注冊(cè)ADN records info監(jiān)聽(tīng)
mCi.registerForAdnRecordsInfo(this, EVENT_LOAD_ADN_RECORD_DONE, null);

try {
    //線(xiàn)程等待,EVENT_LOAD_ADN_RECORD_DONE消息處理完(實(shí)際是EVENT_LOAD_ALL_ADN_LIKE_DONE)后notify喚醒
    mLock.wait();
} catch (InterruptedException e) {
    Rlog.e(LOG_TAG, "Interrupted Exception in queryAdnRecord");
}
//取消監(jiān)聽(tīng)
mCi.unregisterForAdnRecordsInfo(this);

}
handlerMessage中的處理：

case EVENT_QUERY_ADN_RECORD_DONE:
                log("Querying ADN record done");
                if (ar.exception != null) {
                    synchronized (mLock) {
                        mLock.notify();
                    }

                    for (Message response : mAdnLoadingWaiters) {
                        sendErrorResponse(response, "Query adn record failed" + ar.exception);
                    }
                    mAdnLoadingWaiters.clear();
                    break;
                }
                mAdnCount = ((int[]) (ar.result))[0];
                mValidAdnCount = ((int[]) (ar.result))[1];
                mEmailCount = ((int[]) (ar.result))[2];
                mValidEmailCount = ((int[]) (ar.result))[3];
                mAddNumCount = ((int[]) (ar.result))[4];
                mValidAddNumCount = ((int[]) (ar.result))[5];
                log("Max ADN count is: " + mAdnCount
                    + ", Valid ADN count is: " + mValidAdnCount

                    + ", Valid Email count is: " + mValidEmailCount
                    + ", Add number count is: " + mAddNumCount
                    + ", Valid Add number count is: " + mValidAddNumCount);

                if(mValidAdnCount == 0 || mRecCount == mValidAdnCount) {
                    sendMessage(obtainMessage(EVENT_LOAD_ALL_ADN_LIKE_DONE));
                }
                break;

            case EVENT_LOAD_ADN_RECORD_DONE:

                }

                SimPhoneBookAdnRecord[] AdnRecordsGroup = (SimPhoneBookAdnRecord[])(ar.result);
                for (int i = 0 ; i < AdnRecordsGroup.length ; i++) {
                    if (AdnRecordsGroup[i] != null) {
                        mSimPbRecords.add(new AdnRecord(0,
                                                AdnRecordsGroup[i].getRecordIndex(),
                                                AdnRecordsGroup[i].getAlphaTag(),

                        mRecCount ++;
                    }
                }

                if(mRecCount == mValidAdnCount) {
                    sendMessage(obtainMessage(EVENT_LOAD_ALL_ADN_LIKE_DONE));
                }

            case EVENT_LOAD_ALL_ADN_LIKE_DONE:
                log("Loading all ADN records done");
                synchronized (mLock) {
                    mLock.notify();
                }

                notifyAndClearWaiters();
                break;

RIL先返回RIL_UNSOL_RESPONSE_ADN_RECORDS,在EVENT_LOAD_ADN_RECORD_DONE事件中處理,更新mSimPbRecords和MRecount;
然后RIL返回getAdnRecord的請(qǐng)求RIL_REQUEST_GET_ADN_RECORD,在EVENT_QUERY_ADN_RECORD_DONE消息處理,獲得Max ADN count/Valid ADN count等數(shù)據(jù)；
然后發(fā)送EVENT_LOAD_ALL_ADN_LIKE_DONE消息，在該消息中mLock.notify()(queryAdnRecord 方法繼續(xù)執(zhí)行解除注冊(cè));
notifyAndClearWaiters方法將之前requestLoadAllAdnLike方法中記錄的messaage消息發(fā)出去，發(fā)給IccPhoneBookInterfaceManager處理；
IccPhoneBookInterfaceManager的getAdnRecordsInEf方法此時(shí)走到waitForResult(),線(xiàn)程wait,在mBaseHandler處理完 message后獲取mRecords,然后喚醒等待線(xiàn)程，getAdnRecordsInEf方法執(zhí)行完畢獲得返回and list。
