Android : 检查手机是否为双卡 [英] Android : Check whether the phone is dual SIM
问题描述
在论坛上查了很多资料，现在我知道双卡手机的两个SIM卡都没有办法找到IMSI或SIM序列号(联系厂家除外).现在我改变的问题是，我们完全可以检测到手机有两个 SIM 卡吗?我相信它可以通过一些智能检测到.我能想到的几种方法是:
After a lot of research on forums, now I know that there is no way to find IMSI or SIM serial number for both the SIM cards in a dual SIM phone (except for contacting the manufacturer). Now my changed question is, can we at all detect that the phone has two SIMs? I believe it can be detected with some intelligence. Few ways I can think of are:
拨打 USSD 代码并跟踪 IMEI 号码的日志(我在印度用 *139# 尝试过此操作.它奏效了.)这将为我提供用于拨打 USSD 代码的 SIM 卡的 IMEI 号码.(推测该手机遵循 android 指南并具有两个 IMEI 号码.)
Dialing an USSD code and tracing the logs for IMEI number (I tried this with *139# in India. It worked.) This will give me IMEI number for the SIM from which I dialed the USSD code. (It is presumed that the phone follows android guidelines and has two IMEI numbers.)
存储 SIM 的 SIM 序列号和/或 IMSI.在检测到任何其他 IMSI/序列号之后，即使手机没有通过跟踪一些日志或一些广播事件处理重新启动(即 SIM 卡被切换).
Storing the SIM serial number and/or IMSI for the SIM. And after detection of any other IMSI/Serial number even if the phone was not rebooted (i.e. the SIM was switched) by tracing some logs or by some broadcast event handling.
通过拨打 *06#，您将看到两个 IMEI 号码.通过某种方式，得到这两个数字.(类似于屏幕捕获和文本图像解析.)
By dialing *06# you will get to see both IMEI numbers. By some way, get those two numbers. (Something like screen capturing and image parsing for text.)
如果有人能想到其他方法，欢迎他们.我真的很感激任何关于这方面的帮助.此外，如果有人有任何制造商 API 的任何信息或联系他们的链接，请与社区人员分享.
If anyone can think of some other ways, they are most welcome. I would really appreciate any kind of help regarding this. Also, if anyone has any information about any manufacturers APIs or links to contact them, please do share with the community people.

2015 年 3 月 23 日更新:
Android 5.1 及以上版本现已提供官方多 SIM 卡 API
其他可能的选择:
您可以使用 Java 反射来获取两个 IMEI 号码.
You can use Java reflection to get both IMEI numbers.
使用这些 IMEI 号码，您可以检查手机是否为双卡.
Using these IMEI numbers you can check whether the phone is a DUAL SIM or not.
尝试以下活动:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TelephonyInfo telephonyInfo = TelephonyInfo.getInstance(this);
String imeiSIM1 = telephonyInfo.getImsiSIM1();
String imeiSIM2 = telephonyInfo.getImsiSIM2();
boolean isSIM1Ready = telephonyInfo.isSIM1Ready();
boolean isSIM2Ready = telephonyInfo.isSIM2Ready();
boolean isDualSIM = telephonyInfo.isDualSIM();
TextView tv = (TextView) findViewById(R.id.tv);
tv.setText(" IME1 : " + imeiSIM1 + "
" +
" IME2 : " + imeiSIM2 + "
" +
" IS DUAL SIM : " + isDualSIM + "
" +
" IS SIM1 READY : " + isSIM1Ready + "
" +
" IS SIM2 READY : " + isSIM2Ready + "
");
}
}
这里是TelephonyInfo.java:
And here is TelephonyInfo.java :
import java.lang.reflect.Method;
import android.content.Context;
import android.telephony.TelephonyManager;
public final class TelephonyInfo {
private static TelephonyInfo telephonyInfo;
private String imeiSIM1;
private String imeiSIM2;
private boolean isSIM1Ready;
private boolean isSIM2Ready;
public String getImsiSIM1() {
return imeiSIM1;
}
/*public static void setImsiSIM1(String imeiSIM1) {
TelephonyInfo.imeiSIM1 = imeiSIM1;
}*/
public String getImsiSIM2() {
return imeiSIM2;
}
/*public static void setImsiSIM2(String imeiSIM2) {
TelephonyInfo.imeiSIM2 = imeiSIM2;
}*/
public boolean isSIM1Ready() {
return isSIM1Ready;
}
/*public static void setSIM1Ready(boolean isSIM1Ready) {
TelephonyInfo.isSIM1Ready = isSIM1Ready;
}*/
public boolean isSIM2Ready() {
return isSIM2Ready;
}
/*public static void setSIM2Ready(boolean isSIM2Ready) {
TelephonyInfo.isSIM2Ready = isSIM2Ready;
}*/
public boolean isDualSIM() {
return imeiSIM2 != null;
}
private TelephonyInfo() {
}
public static TelephonyInfo getInstance(Context context){
if(telephonyInfo == null) {
telephonyInfo = new TelephonyInfo();
TelephonyManager telephonyManager = ((TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE));
telephonyInfo.imeiSIM1 = telephonyManager.getDeviceId();;
telephonyInfo.imeiSIM2 = null;
try {
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceIdGemini", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceIdGemini", 1);
} catch (GeminiMethodNotFoundException e) {
e.printStackTrace();
try {
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceId", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceId", 1);
} catch (GeminiMethodNotFoundException e1) {
//Call here for next manufacturer's predicted method name if you wish
e1.printStackTrace();
}
}
telephonyInfo.isSIM1Ready = telephonyManager.getSimState() == TelephonyManager.SIM_STATE_READY;
telephonyInfo.isSIM2Ready = false;
try {
telephonyInfo.isSIM1Ready = getSIMStateBySlot(context, "getSimStateGemini", 0);
telephonyInfo.isSIM2Ready = getSIMStateBySlot(context, "getSimStateGemini", 1);
} catch (GeminiMethodNotFoundException e) {
e.printStackTrace();
try {
telephonyInfo.isSIM1Ready = getSIMStateBySlot(context, "getSimState", 0);
telephonyInfo.isSIM2Ready = getSIMStateBySlot(context, "getSimState", 1);
} catch (GeminiMethodNotFoundException e1) {
//Call here for next manufacturer's predicted method name if you wish
e1.printStackTrace();
}
}
}
return telephonyInfo;
}
private static String getDeviceIdBySlot(Context context, String predictedMethodName, int slotID) throws GeminiMethodNotFoundException {
String imei = null;
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
try{
Class<?> telephonyClass = Class.forName(telephony.getClass().getName());
Class<?>[] parameter = new Class[1];
parameter[0] = int.class;
Method getSimID = telephonyClass.getMethod(predictedMethodName, parameter);
Object[] obParameter = new Object[1];
obParameter[0] = slotID;
Object ob_phone = getSimID.invoke(telephony, obParameter);
if(ob_phone != null){
imei = ob_phone.toString();
}
} catch (Exception e) {
e.printStackTrace();
throw new GeminiMethodNotFoundException(predictedMethodName);
}
return imei;
}
private static boolean getSIMStateBySlot(Context context, String predictedMethodName, int slotID) throws GeminiMethodNotFoundException {
boolean isReady = false;
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
try{
Class<?> telephonyClass = Class.forName(telephony.getClass().getName());
Class<?>[] parameter = new Class[1];
parameter[0] = int.class;
Method getSimStateGemini = telephonyClass.getMethod(predictedMethodName, parameter);
Object[] obParameter = new Object[1];
obParameter[0] = slotID;
Object ob_phone = getSimStateGemini.invoke(telephony, obParameter);
if(ob_phone != null){
int simState = Integer.parseInt(ob_phone.toString());
if(simState == TelephonyManager.SIM_STATE_READY){
isReady = true;
}
}
} catch (Exception e) {
e.printStackTrace();
throw new GeminiMethodNotFoundException(predictedMethodName);
}
return isReady;
}
private static class GeminiMethodNotFoundException extends Exception {
private static final long serialVersionUID = -996812356902545308L;
public GeminiMethodNotFoundException(String info) {
super(info);
}
}
}
获取诸如getDeviceIdGemini"之类的方法以获取其他 SIM 卡插槽的详细信息，可以预测该方法存在.
Getting access of methods like "getDeviceIdGemini" for other SIM slot's detail has prediction that method exist.
如果该方法的名称与设备制造商提供的名称不匹配，则它将不起作用.您必须为这些设备找到相应的方法名称.
If that method's name doesn't match with one given by device manufacturer than it will not work. You have to find corresponding method name for those devices.
可以使用Java反射找到其他制造商的方法名称，如下所示:
Finding method names for other manufacturers can be done using Java reflection as follows :
public static void printTelephonyManagerMethodNamesForThisDevice(Context context) {
TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
Class<?> telephonyClass;
try {
telephonyClass = Class.forName(telephony.getClass().getName());
Method[] methods = telephonyClass.getMethods();
for (int idx = 0; idx < methods.length; idx++) {
System.out.println("
" + methods[idx] + " declared by " + methods[idx].getDeclaringClass());
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
正如 Seetha 在评论中指出的那样:
As Seetha pointed out in her comment :
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getDeviceIdDs", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getDeviceIdDs", 1);
这对她有用.她成功地为 Samsung Duos 设备中的两个 SIM 卡获取了两个 IMEI 号码.
It is working for her. She was successful in getting two IMEI numbers for both the SIM in Samsung Duos device.
添加<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
编辑 2:
用于检索数据的方法适用于联想 A319 和该制造商的其他手机(来源 Maher Abuthraa):
The method used for retrieving data is for Lenovo A319 and other phones by that manufacture (Credit Maher Abuthraa):
telephonyInfo.imeiSIM1 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 0);
telephonyInfo.imeiSIM2 = getDeviceIdBySlot(context, "getSimSerialNumberGemini", 1);
