You can use startActivityForResult() when launching Activity from your App and then check if getCallingActivity() returns null. If it does, your activity has been launched from notification.

There already were several questions on this topic:

As of the home screen part, as far as I know there is no way to detect that.

However, you can detect whether your activity is launched from the notification icon:

When setting up your notification, you put an extra into it's PendingIntent, say fromNotification: boolean.
In your main activity's onCreate method you check the intent's extras, and if (there are any and) the fromNotification is among them with the value true, than you know it has been invoked by clikcing on the notification icon.
