The dreaded VerifyError: Error #1014

Whenever you get that error while using an Adobe Native Extension, start by verifying that you're not forgetting to link the extension in your app.xml, like this :

<extensions>
    <extensionID>com.freshplanet.AirFacebook</extensionID>
    <extensionID>com.freshplanet.AirInAppPurchase</extensionID>
</extensions>
