在两个模拟器之间发送的Android数据SMS在传输过程中被截断

Question

我找不到这个问题的答案.为什么从一个仿真器实例以编程方式发送到另一个仿真器实例的数据SMS的长度在接收端被截断？
这里我从模拟器-554发送20个字节到模拟器-556,但模拟器-556 只接收12个字节:

模拟器-554:短信发送者

/** Send data SMS between two emulators from 15555215554 to 15555215556. */
private void sendSMS()
{
    final int udLength = 20;  // SMS user data length in bytes
    Log.d("SMS TEST", "SMSActivity.sendSMS ud.length=" + udLength);
    byte[] payload = new byte[udLength];
    for (byte i = 0; i < udLength; i++)
    {
        Log.d("SMS TEST", "payload[" + i + "]=" + i);
        payload[i] = i;
    }

    Intent smsSentIntent = new Intent("SMS_SENT");
    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, smsSentIntent, 0);
    String destTelephone = "15555215556";
    SmsManager smsMgr = SmsManager.getDefault();       
    smsMgr.sendDataMessage(destTelephone, null, (short) 32766, payload, sentPI, null);
    Log.d("SMS TEST", "SMSActivity.sendSMS COMPLETED!");
}

如您所见,只收到数据消息的前11个字节.
DDMS仿真器控制面板设置是Data=home, Speed=Full, Latency=None.
使用:Android Development Toolkit 16.0.1.v201112150204-238534
AVD目标:Android 2.2 (API level 8)
Eclipse SDK 3.6.2

这是一个模拟器问题吗？其他人可以复制这种行为吗？我一直坚持这个问题太久了.任何帮助将非常感激!

可能与端口号有关。尝试使用小于256的端口号。
