Android - how to unregister a receiver created in the manifest?

I know about using registerReceiver and unregisterReceiver in Java code for dealing with receivers, but let's say I have the following in my manifest:

    <receiver android:name=".headsetHook">
        <intent-filter android:priority="99999999999">
            <action android:name="android.intent.action.ACTION_HEADSET_PLUG" />
        </intent-filter>
    </receiver>

Is there a way I could unregister this somewhere in Java code? Could I give it an id attribute or something and then get it and unregister it? I ask because I want my app to do something only on the first time this action happens, then unregister it and re-register it later in Java.

Hope I made that clear, thanks for any help.
