Android SMS传递意图始终返回-1 [英] Android SMS Delivery Intent always return -1

问题描述

我在Android上遇到一个奇怪的问题.通过应用程序发送短信时，我想听听传递意图.这是我到目前为止所做的:

I'm facing a weird problem on Android. I want to listen for a delivery intent when I send a text message through my app. Here is what I've done so far:

private void shootSMS(String number,long currentTime){
    SmsManager smsManager = SmsManager.getDefault();

    Intent sentIntent = new Intent(SentBroadcastReceiver.SENT_ACTION);
    Intent deliveredIntent = new Intent(DeliveredBroadcastReceiver.DELIVERED_ACTION);

    Bundle b = new Bundle();
    b.putString("num",number);
    b.putString("record_time",currentTime+"");

    sentIntent.putExtras(b);
    deliveredIntent.putExtras(b);


    PendingIntent sentPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,sentIntent,PendingIntent.FLAG_ONE_SHOT);
    PendingIntent deliveredPendingIntent = PendingIntent.getBroadcast(this,(int)currentTime,deliveredIntent,PendingIntent.FLAG_ONE_SHOT);
    smsManager.sendTextMessage(number,null,getString(R.string.app_name),sentPendingIntent,deliveredPendingIntent);

}

现在的问题是，当调用广播接收器的onReceive()方法时，我会调用getResultCode()方法，并且它始终返回-1！即使手机处于关机状态，也无法跟踪短信是否已发送！

Now the problem is that when the onReceive() methods of my broadcast receivers are called I call the getResultCode() method, and it always return -1! Even if the phone is turned off, so it makes it impossible to track whether the SMS is delivered or not!

我用GoSMSPro检查了该号码并发送了一条失败的SMS.有趣的是，当我将手机置于飞行模式时，得到的结果代码等于2，即SmsManager.RESULT_ERROR_RADIO_OFF

I checked the number with the GoSMSPro and sent a SMS which failed. The interesting thing is that when I put my phone in Airplane Mode I get a Result Code equal to 2 which is SmsManager.RESULT_ERROR_RADIO_OFF

现在的问题是，这是怎么了?

Now the question is what's wrong in here?

推荐答案

尝试这种方法: 要发送短信，请使用SMS管理器中的sendTextMessage.

Try This approach : To send a text message use sendTextMessage from SMS Manager.

 sendTextMessage(String destinationAddress, String  scAddress, String text,PendingIntent sentIntent, PendingIntent deliveryIntent)

成功发送消息或发送失败消息时，将触发第一个Pending Intent参数(sentIntent).接收到该Intent的广播接收者的结果代码将是以下之一.

The first Pending Intent parameter (sentIntent) is fired when the message is either successfully sent or failed. The result code for the Broadcast receiever that receives this Intent will be one of the following.

Activity.RESULT_OK - To indicate a successful transmission.
Sms.Manager.RESULT_ERROR_GENERIC_FAILURE - To indicate a nonspecific failure
Sms.Manager.RESULT_ERROR_RADIO_OFF - To indicate the phone radio is turned off
Sms.Manager.RESULT_ERROR_NULL_PDU - To indicate a PDU failure.
SmsManager.RESULT_ERROR_NO_SERVICE - To indicate that no cellular service is currently available.

仅当收件人收到您的SMS消息后，才会触发第二个待处理参数(deliveryIntent).

The second Pending parameter(deliveryIntent) is fired only after the recipient receives your SMS message.

发送和传递事件后，通过Toast显示适当的消息.

After sent and delivery events display appropriate messages through Toast.
