SubscriptionManager
Subscription可以理解为卡上的一个信息单元，里面包含了卡的一些必要信息。
SubscriptionData是Subscription的一个集合。
SubscriptionManager总体上是一个Handler，主要以消息驱动。
维护几个信息：
1.用户指定的Subscription
2.当前激活的Subscription
3.准备好的Subscription ，依赖于卡状态的主动上报
4.当前的数据Subscription
5.设置Subscription模式？
提供两个功能：
1. 激活或去激活Subscription
2. 设置数据Subscription
3. Modem修改了卡状态以后会同步做出反应
内部类：
1. SetUiccSubsParams 设定两个值：subId和SubscriptionStatus
2. PhoneSubscriptionInfo 维护SubscriptionManager中管理的Subscription信息
/**
* Subscription Id
*/
private enum SubscriptionId {
SUB1,
SUB2
}
这里固定了subId的叫法，与习惯不一样。
SubscriptionManager使用单例模式，但是使用getInstance()有可能得到null。
在构造SubscriptionManager的时候，会先调用getUserPreferredSubs()来把存在数据库里的卡的Subscription信息还原回mUserPrefSubs（一个SubscriptionData），如果没有就设定无效的值进去，且保存回数据库。
实例化一个CardSubscriptionManager对象，向这个对象注册三个事件：
registerForCardInfoAvailable——EVENT_CARD_INFO_AVAILABLE
registerForCardInfoUnavailable——EVENT_CARD_INFO_NOT_AVAILABLE
registerForAllCardsInfoAvailable——EVENT_ALL_CARD_INFO_AVAILABLE
向每一个Ril实例，注册三个事件：
registerForSubscriptionStatusChanged——EVENT_SUBSCRIPTION_STATUS_CHANGED
registerForOffOrNotAvailable——EVENT_RADIO_OFF_OR_NOT_AVAILABLE
registerForOn——EVENT_RADIO_ON
实例化两个激活/去激活注册器列表：
mSubDeactivatedRegistrants
mSubActivatedRegistrants
实例化两个激活/去激活队列：
mActivatePending
mDeactivatePending
从MSimPhoneFactory.getDataSubscription()获取当前数据通道使用的是哪一个Subscription
实例化mCurrentSubscriptions队列
private void updateSubPreferences() { int activeSubCount = 0; Subscription activeSub = null; for (SubscriptionId sub: SubscriptionId.values()) { 看有几个激活的sub if (getCurrentSubscriptionStatus(sub) == SubscriptionStatus.SUB_ACTIVATED) { activeSubCount++; activeSub = getCurrentSubscription(sub); } } // If there is only one active subscription, set user preferred settings // for voice/sms/data subscription to this subscription. 只有一个卡激活 if (activeSubCount == 1) { if (MSimPhoneFactory.getDefaultSubscription() != activeSub.subId) { 设置这个卡为voice/sms/data的默认 MSimPhoneFactory.setDefaultSubscription(activeSub.subId); } 如果当前的数据通道不是这张激活的卡，设置这张卡为默认数据通道。 if (mCurrentDds != activeSub.subId) { Log.i(LOG_TAG,"mCurrentDds != activeSub.subId "); Log.i(LOG_TAG,"activeSub = "+activeSub); // Currently selected DDS subscription is not in activated state. // So set the DDS to the only active subscription available now. // Directly set the Data Subscription Source to the only activeSub if it // is READY. If the SUBSCRIPTION_READY event is not yet received on this // subscription, wait for the event to set the Data Subscription Source. SubscriptionId subId = SubscriptionId.values()[activeSub.subId]; 这张卡的状态要ready if (getCurrentSubscriptionReadiness(subId)) { mQueuedDds = activeSub.subId; Message callback = Message.obtain(this, EVENT_SET_DATA_SUBSCRIPTION_DONE, Integer.toString(activeSub.subId)); logd("update setDataSubscription to " + activeSub.subId); mCi[activeSub.subId].setDataSubscription(callback); mSetDdsRequired = false; } else { 如果不ready，就置一个标志位，等ready了再设置，在别的函数里 Log.i(LOG_TAG,"mQueuedDds = activeSub.subId"); // Set the flag and update the mCurrentDds, so that when subscription // ready event receives, it will set the dds properly. mSetDdsRequired = true; mCurrentDds = activeSub.subId; //MSimPhoneFactory.setDataSubscription(mCurrentDds); } } }else if (activeSubCount > 1){ 两张卡都激活了 int preferredDataSub = MSimPhoneFactory.getUserPreferredDDS(); 如果现在的数据通道不是用户选择的那个，处理方式同上 if (mCurrentDds != preferredDataSub){ logd("current dds is "+mCurrentDds+",preferred one is "+preferredDataSub); if (getCurrentSubscriptionReadiness(SubscriptionId.values()[preferredDataSub])){ mQueuedDds = preferredDataSub; Message callback = Message.obtain(this,EVENT_SET_DATA_SUBSCRIPTION_DONE, Integer.toString(preferredDataSub)); logd("update dds to "+preferredDataSub); mCi[preferredDataSub].setDataSubscription(callback); }else{ logd("updata dds later"); mSetDdsRequired = true; mCurrentDds = preferredDataSub; } } }}
