參考：MTK文檔- [FAQ13795]如何修改默認數據連接(Android L)
L上控制默認數據連接開關的位置在DataSubSelector.java中
(alps\frameworks\opt\telephony\src\java\com\mediatek\internal\telephony\dataconnection)
對於OM(Open Market),OP01,OP02(某些版本也會包含OP09)，會有不同的smart switch機制
對於OM版本來說，smart switch機制實現主要在subSelectorForOm方法中
這裏面列舉了C0~C8九種不同的SIM卡狀態下sim switch的選擇，具體可參考註釋
舉例來說，對於開機是兩張新卡的情況下，要默認開啓數據連接的話，將如下的setDataEnable(false)改爲setDataEnable(true);
if (isAllNewSim) {
// Case 4: Multi SIM + All New SIM:
// 1. Default Data: Unset
// 2. Data Enable: OFF
// 3. 34G: Sub1
log(“C4: Multi SIM + All New SIM: Set 34G to sub1”);
if (setCapability(PhoneConstants.SIM_ID_1)) {
setDefaultData(SubscriptionManager.INVALID_PHONE_ID);
}
->setDataEnable(false);
} else {
PS:
setCapability()是設定3,4G能力在哪張卡上
setDefaultData()是設定數據連接在哪張卡上
