apn(access point names)，每个卡都会对应一系列的apn，如主卡为联通卡，对应的apn有3gwap/3gnet/uninet/nuiwap/3gwap等。每个卡默认选择一个apn，用户可更改。
1. 获取主卡或副卡当前使用的apn，对应的uri地址："content://telephony/carriers/preferapn"。
APN getAPN(int subId)
Uri PREFERAPN_URI = Uri.parse("content://telephony/carriers/preferapn");
uri = Uri.withAppendedPath(PREFERAPN_URI, "/subId/" + subId);slotId和subId：可以根据卡槽的slotId得到subId：
int subId = MtkSubscriptionManager.getSubIdUsingPhoneId(slotId);2. 获取主卡或副卡所有的apn列表，对应的uri地址："content://telephony/carriers"。
List<APN> getApnList(int subId)//某个卡槽对应的APN列表
uri = Uri.parse("content://telephony/carriers");
String mccmnc = mTelephonyManager.getSimOperator(subId);//where条件根据mccmnc得到
//主副卡，可根据current来区分，"current = 1"，表示在使用的sim卡，即主卡。"current = ０"，为副卡。3. 针对某个卡增加apn
boolean addApn(APN newApn)
uri = Uri.parse("content://telephony/carriers");4. 更新或删除某个卡的某一apn
boolean update(APN apn)
boolean update(APN apn)
boolean removeAPN(APN apn)
int pos = Integer.parseInt(apn.apnkey);
mUri = Uri.parse("content://telephony/carriers");
uri = ContentUris.withAppendedId(mUri, pos);
5. 恢复apn到默认状态
boolean restoreDefaultApn(int subId) //把某个卡槽对应的APN恢复到默认值
Uri DEFAULTAPN_URI = Uri.parse("content://telephony/carriers/restore");
uri = Uri.withAppendedPath(DEFAULTAPN_URI, "/subId/" + subId);若是插入双卡，只要一个卡执行该功能，两个卡的apn都会恢复到初始值。
