在某些手机中发送短信时出现一般故障

Question

我正在尝试使用普遍可用的代码发送少于 160 个字符的 SMS。但是对于某些手机，我遇到了一般故障。我也授予了所有短信读/写权限。我尝试了两种方式 - 有和没有电话号码的国家代码，但仍然得到同样的错误。为什么我收到此错误？下面是代码。

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

    PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
            new Intent(SENT), 0);

    PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED), 0);

    //---when the SMS has been sent---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {

            if(getResultCode()== Activity.RESULT_OK){
                Toast.makeText(getBaseContext(), "SMS sent",
                        Toast.LENGTH_SHORT).show();
            } else if (getResultCode()== SmsManager.RESULT_ERROR_GENERIC_FAILURE){
                Toast.makeText(getBaseContext(), "Generic failure",
                        Toast.LENGTH_SHORT).show();
            } else if (getResultCode() == SmsManager.RESULT_ERROR_NO_SERVICE){
                Toast.makeText(getBaseContext(), "No service",
                        Toast.LENGTH_SHORT).show();
            }else if (getResultCode() == SmsManager.RESULT_ERROR_NULL_PDU){
                Toast.makeText(getBaseContext(), "Null PDU",
                        Toast.LENGTH_SHORT).show();
            }else if (getResultCode() == SmsManager.RESULT_ERROR_RADIO_OFF){
                Toast.makeText(getBaseContext(), "Radio off",
                        Toast.LENGTH_SHORT).show();
            }else {
                Toast.makeText(getBaseContext(), "Unknown error!!",
                        Toast.LENGTH_SHORT).show();
            }


        }
    }, new IntentFilter(SENT));

    //---when the SMS has been delivered---
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context arg0, Intent arg1) {
            switch (getResultCode())
            {
                case Activity.RESULT_OK:
                    Toast.makeText(getBaseContext(), "SMS delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
                case Activity.RESULT_CANCELED:
                    Toast.makeText(getBaseContext(), "SMS not delivered",
                            Toast.LENGTH_SHORT).show();
                    break;
            }
        }
    }, new IntentFilter(DELIVERED));

    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);

    //ArrayList<String> texts = sms.divideMessage(message);
    //sms.sendMultipartTextMessage(phoneNumber, null, texts, null, null);

}

以下是我授予的权限。

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

这些手机的 API 是否高于或等于 6.0。如果是这样，您需要明确/以编程方式请求许可。
