I have been working on building a standalone custom unitypackage comprising of combined libraries for both iOS and Android platforms. The folder structure after importing the package in a test project contains two folders inside Assets named IosLibrary and Plugins->Android. The folder IosLibrary contains all the resources and libraries required for iOS build and the content of Android folder consists of resources and libraries used for Android build.
I have tested the integration of our package with Unity 4.7 where everything worked fine; when I build the project for iOS platform, the Xcode project for iOS contains resources/headers/libraries required for iOS build. When I tried creating a test project with same package on 5.4, the Xcode project created by Unity started to include resources in Plugins/Android (as shown in the attachment) that results in bunch of build errors as shown below.
Has anyone come across this before ? I would appreciate if someone can point out if there is something I am missing or have done incorrectly.
