android 添加apn数据到卡二

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"。

  1.     APN getAPN(int subId)
  2.         Uri PREFERAPN_URI = Uri.parse("content://telephony/carriers/preferapn");
  3.         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"。

  1.     List<APN> getApnList(int subId)//某个卡槽对应的APN列表
  2.         uri = Uri.parse("content://telephony/carriers");
  3.         String mccmnc = mTelephonyManager.getSimOperator(subId);//where条件根据mccmnc得到
  4.         //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

  1.      boolean addApn(APN newApn)
  2.         uri = Uri.parse("content://telephony/carriers");

4. 更新或删除某个卡的某一apn
    boolean update(APN apn)

  1.     boolean update(APN apn)
  2.     boolean removeAPN(APN apn)
  3.         int pos = Integer.parseInt(apn.apnkey);    
  4.         mUri = Uri.parse("content://telephony/carriers");
  5.         uri = ContentUris.withAppendedId(mUri, pos);

5. 恢复apn到默认状态  

  1.  boolean restoreDefaultApn(int subId) //把某个卡槽对应的APN恢复到默认值
  2.         Uri DEFAULTAPN_URI = Uri.parse("content://telephony/carriers/restore");
  3.         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。

6. 代码如下

  1. public class MyAPNManager {
  2. 	private static final String TAG = "MyAPNManager";
  3. 	private static final boolean DEBUG = true;
  4.  
  5.

  8.     private static final Uri DEFAULTAPN_URI = Uri.parse(RESTORE_CARRIERS_URI);
  9.     private static final Uri PREFERAPN_URI = Uri.parse(PREFERRED_APN_URI);
  10. 	/**
