Android 手机读取SIM卡信息

手机和 wifi 已经改变了人们的生活方式，成为生活的必需品。手机号码和宽带账号成为运营商相互竞争的重要一环，双卡双待的手机需求也逐渐增大，大多数手机厂商将主打手机改为双卡双待全网通，而运营商在占领主SIM卡后，对SIM卡2的欲望越来越大，获取SIM卡2的信息的需求也变大，只有知己知彼，才能占得先机。

这里简单介绍一下 Android 手机如何读取 Sim 卡信息

必要权限： {@link android.Manifest.permission#READ_PHONE_STATE READ_PHONE_STATE}

可以通过 ContentProvider 进行查询

slotId 卡槽ID 双卡的基本就是0,1

phoneId 电话ID 与 slotId 基本相同，双卡基本都是0,1，不过在源码 getDeviceId 方法中有个FIXME注释 // FIXME this assumes phoneId == slotId 因此Android源码也只是假设 phoneId == slotId，可能会在以后修改 phoneId

subId 在 TelephonyManager 类中最常用的ID，但也是最不固定的ID，随着使用手机号码的增加，这个值递增，其实本质就是siminfo的_id

使用 SubscriptionManager 类进行读取信息

通过 SubscriptionInfo 的实例进行读取信息,对应的是 Siminfo 的表字段，下面为该类源码：

该类没有常用的手机IMEI值和IMSI值，这个值可以通过 TelephonyManager 进行读取，不过需要通过反射，具体可见下方关于 TelephonyManager 的介绍

使用 TelephonyManager 读取SIM卡信息：

TelephonyManager 仅能读取默认卡的信息，几乎所有的通过ID读取副卡信息的接口都添加了@hide 注释，无法使用，因此只能通过反射的机制进行调取

读取副卡信息大多只需要1个参数，slotId 或者 subId，源码方法如下(我们主要关心的是IMEI和IMSI，主要看getDeviceId和getSubscriberId方法)：

Requires Permission: * {@link android.Manifest.permission#READ_PHONE_STATE READ_PHONE_STATE} * * @param slotId of which deviceID is returned */ public String getDeviceId(int slotId) { // FIXME this assumes phoneId == slotId try { IPhoneSubInfo info = getSubscriberInfo(); if (info == null) return null; return info.getDeviceIdForPhone(slotId, mContext.getOpPackageName()); } catch (RemoteException ex) { return null; } catch (NullPointerException ex) { return null; } } /** * Returns the unique subscriber ID, for example, the IMSI for a GSM phone * for a subscription. * Return null if it is unavailable. *

* Requires Permission: * {@link android.Manifest.permission#READ_PHONE_STATE READ_PHONE_STATE} * * @param subId whose subscriber id is returned * @hide */ public String getSubscriberId(int subId) { try { IPhoneSubInfo info = getSubscriberInfo(); if (info == null) return null; return info.getSubscriberIdForSubscriber(subId, mContext.getOpPackageName()); } catch (RemoteException ex) { return null; } catch (NullPointerException ex) { // This could happen before phone restarts due to crashing return null; } } /** * Returns the Service Provider Name (SPN). * * @hide */ public String getSimOperatorNameForPhone(int phoneId) { return getTelephonyProperty(phoneId, TelephonyProperties.PROPERTY_ICC_OPERATOR_ALPHA, ""); } /** * Returns the numeric name (MCC+MNC) of current registered operator * for a particular subscription. *

* Availability: Only when user is registered to a network. Result may be * unreliable on CDMA networks (use {@link #getPhoneType()} to determine if * on a CDMA network). * * @param phoneId * @hide **/ public String getNetworkOperatorForPhone(int phoneId) { return getTelephonyProperty(phoneId, TelephonyProperties.PROPERTY_OPERATOR_NUMERIC, ""); } /** * Returns the phone number string for line 1, for example, the MSISDN * for a GSM phone for a particular subscription. Return null if it is unavailable. *

* Requires Permission: * {@link android.Manifest.permission#READ_PHONE_STATE READ_PHONE_STATE} * OR * {@link android.Manifest.permission#READ_SMS} *

* The default SMS app can also use this. * * @param subId whose phone number for line 1 is returned * @hide */ public String getLine1Number(int subId) { String number = null; try { ITelephony telephony = getITelephony(); if (telephony != null) number = telephony.getLine1NumberForDisplay(subId, mContext.getOpPackageName()); } catch (RemoteException ex) { } catch (NullPointerException ex) { } if (number != null) { return number; } try { IPhoneSubInfo info = getSubscriberInfo(); if (info == null) return null; return info.getLine1NumberForSubscriber(subId, mContext.getOpPackageName()); } catch (RemoteException ex) { return null; } catch (NullPointerException ex) { // This could happen before phone restarts due to crashing return null; } } /** * Returns the serial number for the given subscription, if applicable. Return null if it is * unavailable. *

* @param subId for which Sim Serial number is returned * Requires Permission: * {@link android.Manifest.permission#READ_PHONE_STATE READ_PHONE_STATE} * @hide */ public String getSimSerialNumber(int subId) { try { IPhoneSubInfo info = getSubscriberInfo(); if (info == null) return null; return info.getIccSerialNumberForSubscriber(subId, mContext.getOpPackageName()); } catch (RemoteException ex) { return null; } catch (NullPointerException ex) { // This could happen before phone restarts due to crashing return null; } } }

可以看到源码中的这些方法均加了 @hide 的参数，无法直接调用，这里就需要用到反射：

现在就可以通过反射进行调用方法读取数据了

特别注意：

电话号码和IMSI值都是用过 subId 进行读取的，这个值很不稳定，不一定就是1或者2，还有可能是3、4、5、6,不一定能读取出来，不过在5.1版本以上可以通过 subscriptionInfo.getSubscriptionId() 获得 subId，可以获得确定的IMEI值和IMSI值

根据 Android 版本的不同，有些方法不一定能反射得到，目前测试4.4没有问题

总结出来一个帮助类 PhoneUtils：
