I want to publish a paid-for app on Amazon app store as well as Google Play. I plan on doing two separate builds for my app, one with the Google Play Licensing library incorporated and enabled (for submitting to Google Play) and one with the Licensing library disabled (for submitting to Amazon app store; Amazon has its own Licensing facility). Other than this, the two builds will be identical (same package name etc). Does anyone know whether or not this strategy is a feasible way to go?
A worry I have in particular is app updates. If a user purchases my app from Amazon app store and I publish an update to Google Play, would the user receive a notification telling them that an update is available for them from Google Play?
