How can I do hardware specific builds?

I want to use the exact same code base for both my iOS and Android builds.

Is there a way to enter a plug-in for use only during an iOS build? In my case, I am trying to use the  openUdid for the iOS version. But when this code is seen during an Android build, I receive an error. Will I have to comment this out every time I want to build for Android, or is there a way to do a conditional-build based upon the build type?

In other words, how can I insert a plug-in for one platform without having to comment it out when building for another platform?

                plugins = {
                        [“plugin.openudid”] = {

                                                              publisherId = “com.coronalabs”

                                                            },
                                },

Thanks to anyone for a good, solid answer.
