android - 如何在 Android 中检索 SIM 卡 IMSI？

Question

public String getSubscriberId(){
    operator = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
    String IMSI = operator.getSubscriberId();
    return IMSI;
}

simID = (TextView) findViewById(R.id.text2);
    simIMSI = getSubscriberId().toString();

    if (simIMSI.equals("")){
        simID.setText("No SIM card detected!");
    }
    else{
        simID.setText(simIMSI.toString());
        SaveUniqueId(simIMSI.toString());
    }

我希望检索手机 SIM 卡 IMSI 并在布局中显示，我使用模拟器运行程序，即使我知道模拟器没有附加 SIM 卡，但它应该有类似“未检测到 SIM 卡”的结果，对吧？但为什么我会收到此编码错误，或者是我的“getSubscriberId()”有问题？

Answer 1

String serviceName = Context.TELEPHONY_SERVICE;
TelephonyManager m_telephonyManager = (TelephonyManager) getSystemService(serviceName);

现在让我们从实际的源代码开始检索信息:-

public String findDeviceID() {
     String deviceID = null;
     String serviceName = Context.TELEPHONY_SERVICE;
     TelephonyManager m_telephonyManager = (TelephonyManager) getSystemService(serviceName);
     int deviceType = m_telephonyManager.getPhoneType();
     switch (deviceType) {
           case (TelephonyManager.PHONE_TYPE_GSM):
           break;
  case (TelephonyManager.PHONE_TYPE_CDMA):
  break;
  case (TelephonyManager.PHONE_TYPE_NONE):
  break;
          default:
         break;
     }
     deviceID = m_telephonyManager.getDeviceId();
     return deviceID;
}
