Android TelephonyManager双sim卡

我已经阅读并尝试了很多关于检测手机是否为双sim卡的解决方案，但每个解决方案都不起作用

我已尝试使用以下代码：

import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;

import android.content.Context;
import android.telephony.TelephonyManager;


public final class TelephonyInfoNew {

    private static TelephonyInfoNew telephonyInfo;
    private String imsiSIM1;
    private String imsiSIM2;
    private boolean isSIM1Ready;
    private boolean isSIM2Ready;

    public String getImsiSIM1() {
        return imsiSIM1;
    }

    /*public static void setImsiSIM1(String imsiSIM1) {
        TelephonyInfo.imsiSIM1 = imsiSIM1;
    }*/

    public String getImsiSIM2() {
        return imsiSIM2;
    }

    /*public static void setImsiSIM2(String imsiSIM2) {
        TelephonyInfo.imsiSIM2 = imsiSIM2;
    }*/

    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 imsiSIM2 != null;
    }

    private TelephonyInfoNew() {
    }

            e.printStackTrace();
        }

        return list;
    } 
}

我总是收到：

imsi1 = 0;
imsi2 = 1;

是否可以解决问题或检测手机是否为双sim卡

非常感谢

我已经阅读并尝试了您链接中描述的方法，但它不起作用

imsi1 = 0;
imsi2 = 1;
