Android sendTextMessage 在执行时发送两条相同的消息

Question

我一直在开发一款发送 SMS 消息的应用程序。我遇到的问题是 sendTextMessage 方法发送两条内容相同的消息。我该如何解决？

这个类启动进程

public class C2DMMessageReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Some stuff
        Log.i("C2DMMessageReceiver", "Got C2DM message");
        SmsSend message = new SmsSend(context, phonenumber, line);
        message.send()
    }
}

发送短信的类

public class SmsSend {
    SmsSend(Context tcontext, String phoneNumber, String smstext){
        context = tcontext;
        phone_number = phoneNumber;
        message = smstext; 
    }

    protected void send(){

        if(foo){
            Log.i("SmsSend", "Sending message");
            SmsManager sms = SmsManager.getDefault();
            String sent = "android.telephony.SmsManager.STATUS_ON_ICC_SENT";
            PendingIntent piSent = PendingIntent.getBroadcast(context, 0, new Intent(sent), 0);
            sms.sendTextMessage(phone_number, null, message, piSent, null);
        }

    }
}

上课，看看发生了什么事

public class SmsSentBroadcastReciever extends BroadcastReceiver{
    private static final String TAG = "SmsSentBroadcastReciever";

    @Override
    public void onReceive(Context context, Intent intent) {
        switch (getResultCode()){
            case Activity.RESULT_OK:
                Log.i(TAG,"SMS sent");
                break;
            case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                Log.e(TAG,"Generic failure");
                break;
            case SmsManager.RESULT_ERROR_NO_SERVICE:
                Log.e(TAG,"No service");
                break;
            case SmsManager.RESULT_ERROR_NULL_PDU:
                Log.e(TAG,"PDU NULL");
                break;
            case SmsManager.RESULT_ERROR_RADIO_OFF:
                Log.e(TAG,"Radio off");
                break;
        }

    }

}

LogCat 的输出是

收到C2DM消息

发送消息

短信已发送

短信已发送

所以 sendTextMessage 只触发一次，但它仍然抛出两条消息。怎么办？

我正在调试的设备是装有 Android 4.0 的 Samsung Galaxy S2。我读到一些旧线程，sendTextMessage 在某些 (HTC) 设备上损坏，所以我尝试使用 sendMultipartTextMessage 但它给出了相同的结果。

以下代码工作正常，S2 与 ICS:

void sendMessageGTI9100ICS(String number, String msg) throws Exception {
    SmsManager m = SmsManager.getDefault();

    Class aclass[] = new Class[9];

    aclass[0] = String.class;
    aclass[1] = String.class;
    aclass[2] = ArrayList.class;
    aclass[3] = ArrayList.class;
    aclass[4] = ArrayList.class;
    aclass[5] = Boolean.TYPE;
    aclass[6] = Integer.TYPE;
    aclass[7] = Integer.TYPE;
    aclass[8] = Integer.TYPE;

    Method method = m.getClass().getMethod("sendMultipartTextMessage", aclass);

    Object aobj[] = new Object[9];
    aobj[0] = number;
    aobj[1] = null;
    aobj[2] = m.divideMessage(msg);
    aobj[3] = null;
    aobj[4] = null;
    aobj[5] = Boolean.valueOf(false);
    aobj[6] = Integer.valueOf(0);
    aobj[7] = Integer.valueOf(0);
    aobj[8] = Integer.valueOf(0);

    method.invoke(m, aobj);
}
