Implementing a BroadcastReceiver in the AndroidManifext.xml File

Question

I am trying to use a BroadcastReceiver in Android (using the manifest) and just had a quick question.

So far I have this...

<receiver android:name=".Listener"
  android:label="testRecv"
  android:enabled="true"
  android:exported="true"
  android:process=":recovery">
  <intent-filter>
    <action android:name="android.intent.action.SCREEN_ON"/>
  </intent-filter>
</receiver>

But when I install the apk on a test device or emulator, nothing is happening what I turn on my screen. Here is the code for the Listener class...

public class Listener extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.intent.action.SCREEN_ON")) {
            Toast t = Toast.makeText(context, "hey", 10);
            t.show();
        }
    }
}

I am never seeing the toast get fired off (as a test).

Is there something I am missing? I never used Context.registerReceiver() because I declared the in the manifest, so I though I didn't need to.

The most confusing part about this whole thing is the and the documentation isn't that helpful for it. Can anybody just help me understand this stuff?
