Justin,
So the donate key app doesn't actually implement any logic? The mere
fact that it is an available package on the phone (means that the user
paid money for the download) is the flag that tells the main app to
unlock code features?
Nice.

Couldn't a user just create their own dummy APK with the same package and
install it to circumvent this?

I actually have mine set up so that if they try to launch the donate key it
will just launch the full version of the app. If the full version of the
app doesn't exist then I display a dialog giving them the option to go the
market
Kindle is allowed to circumvent the Market because Amazon is selling digital
content or goods that may be consumed outside of the application itself.
This is not the same as unlocking a feature (e.g. the removal of ads) in
ones app.
See *Paid and Free Applications *in* *
I do this with AppSwipe! on the Market. The main app is free and there is
also a donate key app. The package names are as follows:
AppSwipe!: com.magouyaware.appswipe
Donate Key: com.magouyaware.appswipe2
To determine if the user has paid for additional features I have this class:
public
