Android学习笔记_SIM卡介绍

Android学习笔记_SIM卡介绍一、判断SIM卡属于哪个移动运营商1、第一种方法:获取手机的IMSI码,并判断是中国移动\中国联通\中国电信TelephonyManager telManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);/**获取SIM卡的IMSI码* SIM卡唯一标识：IMSI 国际移动用户识别码（IMSI：International Mobile Subscriber Identification Number）是区别移动用户的标志，* 储存在SIM卡中，可用于区别移动用户的有效信息。

IMSI由MCC、MNC、MSIN 组成，其中MCC为移动国家号码，由3位数字组成，* 唯一地识别移动客户所属的国家，我国为460；MNC为网络id，由2位数字组成，* 用于识别移动客户所归属的移动网络，中国移动为00，中国联通为01,中国电信为03；MSIN为移动客户识别码，采用等长11位数字构成。

* 唯一地识别国内GSM移动通信网中移动客户。

所以要区分是移动还是联通，只需取得SIM卡中的MNC字段即可*/String imsi = telManager.getSubscriberId();if(imsi!=null){if(imsi.startsWith("46000") || imsi.startsWith("46002")){//因为移动网络编号46000下的IMSI已经用完，所以虚拟了一个46002编号，134/159号段使用了此编号//中国移动}else if(imsi.startsWith("46001")){//中国联通}else if(imsi.startsWith("46003")){//中国电信}}2、第二种方法：TelephonyManager telManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);String operator = telManager.getSimOperator();if(operator!=null){if(operator.equals("46000") || operator.equals("46002")){//中国移动}else if(operator.equals("46001")){//中国联通}else if(operator.equals("46003")){//中国电信}}二、从SIM卡中获取联系人信息1、可以通过内容提供者进行访问，下面是主要代码。

Uri uri = Uri.parse("content://icc/adn");String[] projection = {"_id", "name", "number"};Cursor cursor = managedQuery(uri, projection, null, null, "name"); if(cursor!=null){while(cursor.moveToNext()){String name = cursor.getString(cursor.getColumnIndex("name"));String phone = cursor.getString(cursor.getColumnIndex("number"));}}/*在文件AndroidManifest.xml中添加权限<uses-permission android:name="android.permission.READ_PHONE_STATE"/>Android系统内部通过Contentprovider对外共享Sim卡存放的联系人等信息，你可以通过操作Contentprovider来实现Sim卡信息的添删改查操作。

AND (type=1 OR type=3)",new String[]{number}, "_id desc limit 1");if(cursor.moveToFirst()){contentResolver.delete(localUri, "_id=?", newString[]{cursor.getString(0)});}cursor.close();}contentResolver.unregisterContentObserver(this);}}。
