android - RESULT_ERROR_NULL_PDU 如果文本太长？

Question

我使用此代码以编程方式发送消息。如果文本太长，我会收到“Null Pdu”。如果很短，则成功发送。怎么了？什么是空 pdu？你能修理伙计们吗？谢谢 4 你的帮助..(抱歉英语不好)

public void onReceive(Context arg0, Intent arg1) {
    switch (getResultCode())
    {
        case Activity.RESULT_OK:
            Toast.makeText(getBaseContext(), "SMS sent", 
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
            Toast.makeText(getBaseContext(), "Generic failure", 
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_NO_SERVICE:
            Toast.makeText(getBaseContext(), "No service", 
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_NULL_PDU:
            Toast.makeText(getBaseContext(), "Null PDU", 
                    Toast.LENGTH_SHORT).show();
            break;
        case SmsManager.RESULT_ERROR_RADIO_OFF:
            Toast.makeText(getBaseContext(), "Radio off", 
                    Toast.LENGTH_SHORT).show();
            break;
    }
}

您必须将所有文本分成几部分，以便它们适合几条短信。或将其作为彩信发送
