title: Which activity handles Intent.ACTION_CALL_PRIVILEGED?
body: <p>I've been digging for awhile into the source of the <a href="http://android.git.kernel.org/?p=platform/packages/apps/Contacts.git;a=tree" rel="noreferrer">Contacts app</a> on Android to find out which Activity handles <code>Intent.ACTION_CALL_PRIVILEGED</code>. Unfortunately, I couldn't find its source code. Does anyone know how it's called, or even better where I can find it's source? Thank you!</p>
