How to send a SMS using java reflection in Dual SIM mobile Moto E ( android version 4.4.4)?

Question

I have tried with code mentioned on this link How to send a SMS using SMSmanager in Dual SIM mobile? I used name for simID is "isms_msim".

try {
        if (simID == 0) {
            name = "isms";
        } else if (simID == 1) {
            name = "isms_msim";
        } else {
            throw new Exception("can not get service which for sim '" + simID + "', only 0,1 accepted as values");
        }
        Method method = Class.forName("android.os.ServiceManager").getDeclaredMethod("getService", String.class);
        method.setAccessible(true);
        Object param = method.invoke(null, name);

        method = Class.forName("com.android.internal.telephony.ISms$Stub").getDeclaredMethod("asInterface", IBinder.class);
        method.setAccessible(true);
        Object stubObj = method.invoke(null, param);
        if (Build.VERSION.SDK_INT < 18) {
            method = stubObj.getClass().getMethod("sendMultipartText", String.class, String.class, List.class, List.class, List.class);
            method.invoke(stubObj, toNum, centerNum, smsTextlist, sentIntentList, deliveryIntentList);
        } else {
            method = stubObj.getClass().getMethod("sendMultipartText", String.class, String.class, String.class, List.class, List.class, List.class);
        ===>    method.invoke(stubObj, ctx.getPackageName(), toNum, centerNum, smsTextlist, sentIntentList, deliveryIntentList);
        }
        return true;
    } catch (ClassNotFoundException e) {
        Logger.Log(TAG, Logger.LogLevel.ERROR, "Error while sending multiple sms, stack trace: " + e.getStackTrace());
    } catch (NoSuchMethodException e) {
        Logger.Log(TAG, Logger.LogLevel.ERROR, "Error while sending multiple sms, stack trace: " + e.getStackTrace());
    } catch (InvocationTargetException e) {
        Logger.Log(TAG, Logger.LogLevel.ERROR, "Error while sending multiple sms, stack trace: " + e.getStackTrace());
    } catch (IllegalAccessException e) {
        Logger.Log(TAG, Logger.LogLevel.ERROR, "Error while sending multiple sms, stack trace: " + e.getStackTrace());
    } catch (Exception e) {
        Logger.Log(TAG, Logger.LogLevel.ERROR, "Error while sending multiple sms, stack trace: " + e.getStackTrace());
    }

but this code is giving following Exception on line starts with ===> in else block: SecurityException: Binder invocation to an incorrect interface

Any Idea about it ?

I got the solution by myself after spending some time. call the API from https://github.com/gp-b2g/frameworks_base/blob/master/telephony/java/android/telephony/MSimSmsManager.java and https://github.com/gp-b2g/frameworks_base/blob/master/telephony/java/android/telephony/MSimTelephonyManager.java file by java reflection to get subscription info and to send SMS.
