Android – How to intercept the ‘Install application’ intent

This isn’t an answer per se, but I can’t find any commenting tool here. Sorry.
I’m having this issue as well. I would like to be able to detect new application installs. I know it is possible – for example, the app Apps to SD posts a notification when you install a new app that when clicked opens a dialog to move that new app to the sd card.
So far, all I’ve been able to figure is like this:
manifest.xml:

...
<receiver android:name=".IntentReceiver">
  <intent-filter>
    <action android:name="android.intent.action.PACKAGE_ADDED" />
    <action android:name="android.intent.action.PACKAGE_REMOVED" />
    <data android:scheme="package" />
  </intent-filter>
</receiver>
...

IntentReciever.java:

public class IntentReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    context.startService(new Intent(context, YourService.class));
  }
}

YourService is then created and calls onCreate() then onStartCommand(). However, I haven’t been able to debug this or successfully display any notifications from the service class, so I’m not entirely sure this works. I have gotten this to work for other Receivers like android.intent.action.BOOT_COMPLETED.
