How to create a new Intent for another app's broadcast receiver?

In the examples, they create Intent as:

Intent intent = new Intent(this, AlarmReceiver.class);

But suppose my AlarmReceiver class is in another app, how do I create this intent?

I've tried with

new Intent("com.app.AlarmReceiver")

but nothing happens.. It was not called..

Any idea?

--Broadcast definition added using the manifest editor on Eclipse:

<receiver android:name="AlarmReceiver"></receiver>

If you wrote the other app, add an <intent-filter> with a custom action string to the other app's <receiver> element, then use an Intent with that action string.

If you did not write the other app, ask whoever wrote it what the Intent should look like.
