ANE for one platform on Flex mobile project for iOS and Android

I'm very new at Flex Mobile Projects and native extension.

I have a big doubt... If I have an ANE that only works on iOS or Android, can I use it into a project for Android AND iOS?

I mean, if I want to do something and I've only found and ANE that works for iOS and another ANE that works for Android, can I create only one project and depending on the device use one or another? or should I create two different projects?

Thanks in advance
