How to decypher intents from javadoc

Question

Hi, I'm starting out with android development, and am really confused by the javadoc on intents. For example I'm trying to launch the intent:

android.provider.ContactsContract.Intents.ATTACH_IMAGE

I try to launch it with:

Intent test = new Intent(ContactsContract.Intents.ATTACH_IMAGE);
startActivity(test);

and it returns an ActivityNotFoundException

The javadoc says:

public static final String ATTACH_IMAGE Since: API Level 5

Starts an Activity that lets the user pick a contact to attach an image to. After picking the contact it launches the image cropper in face detection mode. Constant Value: "com.android.contacts.action.ATTACH_IMAGE"

Can anyone explain how to interpret this and launch the intent properly?

Thanks! David.
