短信发送失败问题

Question

我只想澄清一些事情。

我正在编写一个简单的代码，在看到它将使用auto_sms回复回复时，标准会侦听传入设备的短信。我在运行Android 4.0 +的设备上尝试过它们似乎没有任何问题，但我一直在运行Android 2.3.4和2.3.6的两个设备上进行测试，两者都在代码时给我以下错误正在尝试发送auto_sms回复。

我认为这取决于导致问题的设备上的Android版本，是否有使代码适用于旧版本的Android？

07-17 03:29:43.710: D/SMSDispatcher(246): mResultReceiver : success = true
07-17 03:29:44.370: D/SMSDispatcher(246): SMS send failed

以下是我用于 Location_SMS_Request类的代码。

        sentPI = PendingIntent.getBroadcast(this, 0, new Intent(SENT), 0);
        deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(DELIVERED), 0);
        contentResolver = getContentResolver();
    }

    @Override

        super.onResume();

        //---create the BroadcastReceiver when the SMS is sent---
