问题描述

我正在使用以下代码在后台一次向多个人(联系人)发送短信. 它适用于较小的文本，但不适用于超过160个字符的文本.我遇到了一般性故障.

I am using below code for sending sms in background for multiple peoples(Contacts) at a time. It is working for smaller text but however it not working for text which has more than 160 characters. I am getting GENERIC FAILURE.

public class SendSMS {

    private int mMessageSentParts;
    private int mMessageSentTotalParts;
    private int mMessageSentCount;
    private String message;
    private String[] array;
    private Context mContext;

    public SendSMS(Context context,String array[]) {
        // TODO Auto-generated constructor stub
        this.mContext = context;
        this.array = array;
        System.out.println("array length :::: "+array.length);
        message = mContext.getResources().getString(R.string.siri);
//      message="siri";
        startSendMessages();
    }

    private void startSendMessages() {

        registerBroadCastReceivers();

        mMessageSentCount = 0;
        sendSMS(array[mMessageSentCount].toString(), message);
    }

    private void sendNextMessage() {
        if (thereAreSmsToSend()) {
            sendSMS(array[mMessageSentCount].toString(), message);
        } else {
            Toast.makeText(mContext, "All SMS have been sent",
                    Toast.LENGTH_SHORT).show();
        }
    }

    private boolean thereAreSmsToSend() {
        return mMessageSentCount < array.length;
    }

    private void sendSMS(final String phoneNumber, String message) {
        String SENT = "SMS_SENT";
        String DELIVERED = "SMS_DELIVERED";

        SmsManager sms = SmsManager.getDefault();
        ArrayList<String> parts = sms.divideMessage(message);
        mMessageSentTotalParts = parts.size();

        Log.i("Message Count", "Message Count: " + mMessageSentTotalParts);

        ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
        ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();

        PendingIntent sentPI = PendingIntent.getBroadcast(mContext, 0, new Intent(
                SENT), 0);
        PendingIntent deliveredPI = PendingIntent.getBroadcast(mContext, 0,
                new Intent(DELIVERED), 0);

        for (int j = 0; j < mMessageSentTotalParts; j++) {
            sentIntents.add(sentPI);
            deliveryIntents.add(deliveredPI);
        }

        mMessageSentParts = 0;
        sms.sendMultipartTextMessage(phoneNumber, null, parts, sentIntents,
                deliveryIntents);
    }

    private void registerBroadCastReceivers() {
