I had the in-app billing integrated in one activity, accessed through the preference menu of the livewallpaper, and it's working fine and dandy. That is, until I tried to cancel an app purchase. The app crashes once I tried to cancel.

The only way I have figured out how to remove this crash is to declare the activity with the following tags:
<!-- BTW, I cannot put this tag on the livewallpaper service itself. It has to be an activity. In my case, this activity is some sort of a purchase window. -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Unfortunately, now that this app is both a launcher and a livewallpaper, there is now an icon in the main menu, and it launches the activity that was tagged earlier. The only way I know how to remove the icon is to removing the LAUNCHER tag programmatically. I don't think this will fly because the in-app billing requires the LAUNCHER tag in the first place, otherwise it will crash again.
Does anyone here have done an in-app billing inside a livewallpaper? Is there any other way to remove this crash? Or maybe a way to remove the icon without removing the LAUNCHER tag?
