Android SMS Delivery Intent always return -1

问题:

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);

}

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!

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

Now the question is what's wrong in here?

回答1:

The documentation on sendTextMessage states:

sentIntent: if not NULL this PendingIntent is broadcast when the message is successfully sent, or failed. The result code will be Activity.RESULT_OK...

If you go look at Activity.RESULT_OK the value is -1.

So the resultCode of -1 is actually RESULT_OK.

In general it is best not to look at numeric values but to try to figure out which constant they are representing.

do like this:

private void sendSms(String phonenumber, String message) {
    SmsManager manager = SmsManager.getDefault();

    PendingIntent piSend = PendingIntent.getBroadcast(this, 0, new Intent(
            SMS_SENT), 0);
    PendingIntent piDelivered = PendingIntent.getBroadcast(this, 0,
            new Intent(SMS_DELIVERED), 0);

        int length = message.length();

        if (length > MAX_SMS_MESSAGE_LENGTH) {
            ArrayList<String> messagelist = manager.divideMessage(message);

            ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
            ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();

            int numParts = messagelist.size();
            ;
            for (int i = 0; i < numParts; i++) {
                sentIntents.add(PendingIntent.getBroadcast(this, 0,
                        new Intent(
                                SMS_SENT), 0));
                deliveryIntents.add(PendingIntent.getBroadcast(this, 0,
                        new Intent(SMS_DELIVERED), 0));
            }

            manager.sendMultipartTextMessage(phonenumber, null,
                    messagelist, sentIntents, deliveryIntents);
        } else {
            manager.sendTextMessage(phonenumber, null, message, piSend,
                    piDelivered);
        }
}  

and your Receiver:
note that use "Activity.RESULT_OK" instead number

private BroadcastReceiver deliveredreceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String info = "Delivery information: ";

        switch (getResultCode()) {
        case Activity.RESULT_OK:
            info += "delivered";
            break;
        case Activity.RESULT_CANCELED:
            info += "not delivered";
            break;
        }

        Toast.makeText(getBaseContext(), info, Toast.LENGTH_SHORT).show();
    }
};  

permission:

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

this permission use for sending and receiving sms.

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

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

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.

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

After sent and delivery events display appropriate messages through Toast.
