Desktop AIR developers are, hopefully, familiar with our advice to implement an auto-update mechanism for your application first, even before you add your first feature. But what should you do on mobile devices or TVs, where the Updater API isn’t available?
On mobile devices and TVs, you should be happy that the platform has already implemented an update mechanism for you. As part of the better-developed application delivery ecosystem on these environments, applications are downloaded from application marketplaces of one type or another. These same marketplaces provide an update mechanism for these applications. Details vary as to whether the updates are installed automatically or require user intervention but, in any case, these will be the update mechanism users on these devices will be expecting.
If you need to write code that works in both places, you can check support at runtime via Updater.isSupported. This is a decision you might want to take into account earlier on, however, since there’s no value in including additional code, like the AIR Updater Framework, in applications targeting mobile or TV.
