export and SDK

We need to understand if it’s possible to export and sdk for iOS and Android instead a final app with Unity.

· For Android we need to have a jar or aar as result for Unity compile

· For iOs we need to have a .a file as result for Unity compile

If this is possible are there any limitation on the usage of this SDK into other native apps? Like incompatibility with other sdks or iOS version.

And what is the average size of this sdk?

thank you so much

Unity is not a sdk. Unity does not genreate .jar/ .aar / .a files as a build.
