It is always worth updating your apps. Corona makes it extremely easy. If you are using some old framework, you can always download it and still use it, even if it is not in the Core distribution anymore. Just drop it to root folder of sources and you’re good, for example, here is storyboard.lua. If you need to migrate really old Google IAP plugin or something, we have easy to follow guides on how to do that.
Updating your apps would make them look better on newer Android phones, and generally helps Google Play Store placement.
But if you can not rebuild app, I made not-so-simple instructions on how you can actually manually edit manifest to “fix” this vulnerability. Make sure to test your app after making this changes:
In nutshell, I use apktool to decompile apk, then edit it’s manifest, then recompile and re-sign it.
Again: do not do that unless you absolutely must to.
