ADN加载流程

A Loity / 2910人阅读

摘要：加载流程定义在从上面可以看到，真正的是在中继承，处理的等操作，和卡交互完成后，将数据改变信息通知给然后将数据变化的发送给注册监听的应用，应用做相应的同步动作。

ADN加载流程：

IccProvider.java
IccProvider定义在/packages/services/Telephony/AndroidManifest.xml

</>复制代码 
  1.   
  2. public class IccProvider extends com.android.internal.telephony.IccProvider {
  3.     public IccProvider() {
  4.         super();
  5.     }
  6. }

从上面可以看到，真正的ICCProvider是在framework中继承ContentProvider，处理ADN/FDN/SDN的query/insert/update/delete等操作，和SIM卡交互完成后，将数据改变信息通知给ContentObserver,然后ContentObserver将数据变化的发送给注册监听的应用，Contacts应用做相应的同步动作。
Contacts数据库和SIM卡联系的同步后面继续分析。
关于ContentProvider和ContentResolver以及ContentObserver的介绍，可以参考：
http://blog.csdn.net/dmk877/a...

IccProvider重写ContentProvider的方法：

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

</>复制代码 
  1. public class UiccPhoneBookController extends IIccPhoneBook.Stub {
  2.     private static final String TAG = "UiccPhoneBookController";
  3.     private Phone[] mPhone;
  4.     /* only one UiccPhoneBookController exists */
  5.     public UiccPhoneBookController(Phone[] phone) {
  6.         if (ServiceManager.getService("simphonebook") == null) {
  7.                ServiceManager.addService("simphonebook", this);
  8.         }
  9.         mPhone = phone;
  10.

IccProvider通过AIDL调用UiccPhoneBookController：

</>复制代码 
  1. try {
  2.             IIccPhoneBook iccIpb = IIccPhoneBook.Stub.asInterface(
  3.                     ServiceManager.getService("simphonebook"));
  4.             if (iccIpb != null) {
  5.                 success = iccIpb.updateAdnRecordsInEfBySearchForSubscriber(subId, efType,
  6.                         "", "", name, number, pin2);
  7.             }
  8.         } catch (RemoteException ex) {
  9.             // ignore it
  10.         } catch (SecurityException ex) {
  11.             if (DBG) log(ex.toString());
  12.         }

关于AIDL的实现后面详细学习
IccPhoneBookInterfaceManager.java
IccPhoneBookInterfaceManager是在Phone的初始化时完成实例化:

</>复制代码 
  1. 在GsmCdmaPhone构造方法initOnce()中：
  2.  mIccPhoneBookIntManager = mTelephonyComponentFactory.makeIccPhoneBookInterfaceManager(this);

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

</>复制代码 
  1.     this.mPhone = phone;
  2.     IccRecords r = phone.getIccRecords();
  3.     if (r != null) {
  4.         mAdnCache = r.getAdnCache();
  5.     }
  6.     if(isSimPhoneBookEnabled()){
  7.         if(mSimPbAdnCache == null) {
  8.             mSimPbAdnCache = new SimPhoneBookAdnRecordCache(
  9.                     phone.getContext(), phone.getPhoneId(), phone.mCi);
  10.         }
  11.     }
  12. }

  55.                 notifyAndClearWaiters();
  56.                 break;

RIL先返回RIL_UNSOL_RESPONSE_ADN_RECORDS,在EVENT_LOAD_ADN_RECORD_DONE事件中处理,更新mSimPbRecords和MRecount;
然后RIL返回getAdnRecord的请求RIL_REQUEST_GET_ADN_RECORD,在EVENT_QUERY_ADN_RECORD_DONE消息处理,获得Max ADN count/Valid ADN count等数据；
然后发送EVENT_LOAD_ALL_ADN_LIKE_DONE消息，在该消息中mLock.notify()(queryAdnRecord 方法继续执行解除注册);
notifyAndClearWaiters方法将之前requestLoadAllAdnLike方法中记录的messaage消息发出去，发给IccPhoneBookInterfaceManager处理；
IccPhoneBookInterfaceManager的getAdnRecordsInEf方法此时走到waitForResult(),线程wait,在mBaseHandler处理完 message后获取mRecords,然后唤醒等待线程，getAdnRecordsInEf方法执行完毕获得返回and list。
