How to know when the phone receives a message

Question

Detecting SMS incoming and outgoing

I want to write a app that run silently. The app needs to be notified about new messages. It just needs to to know when a new message is received, doesn't need to read the content of the message.

How can I achieve this?

Update: Is there a function which checks if there are any new messages at a given time. My idea is to then put this check in a loop, and check for new messages regularily.

don't loop it, it will slow down your application and waste processing. Try implementing some event listener to actively notify when there is an oncoming sms. — Johnydep, Feb 11 '12 at 17:20

This is a good tutorial on both sending and receiving sms messages: http://mobiforge.com/developing/story/sms-messaging-android .

For the incoming messages you can indeed configure a broadcastlistener for detection. *

Detecting outgoing messages is also possible: http://www.mail-archive.com/android-developers@googlegroups.com/msg26420.html

ContentResolver contentResolver = context.getContentResolver();
  contentResolver.registerContentObserver(Uri.parse("content://
sms"),true, myObserver);
