Android send SMS automatically on button click

Question

I am trying to automatically send SMS message to a certain number when the user presses a button on the screen.

This is my code:

Intent smsIntent = n         


        

Answer 1

Try this

private static final String SMS_SENT_INTENT_FILTER = "com.yourapp.sms_send";
private static final String SMS_DELIVERED_INTENT_FILTER = "com.yourapp.sms_delivered";

String message = "hey, this is my message";

String phnNo = " " //preferable use complete international number

PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, new Intent(
                SMS_SENT_INTENT_FILTER), 0);
PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, new Intent(
                SMS_DELIVERED_INTENT_FILTER), 0);

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