Platform Specific renderers can be found in the following namespaces:

iOS: Xamarin.Forms.Platform.iOS
Android: Xamarin.Forms.Platform.Android
Windows Phone: Xamarin.Forms.Platform.WinPhone

Base Renderer
To start with, all renders usually derive from a platform specific base renderer class that in turn inherit from a platform specific control.  If you want to create platform specific renderers from scratch you are probably going to be deriving them from the correct platform's base renderer class.  These have been substantially standardized in version 6201 with all controls inheriting from a generic version of ViewRenderer.  There is also a non-generic version that appears to be used sometimes by navigation controls.  The methods on these classes are also more in line with each other than they had been but still not the same.  For example the iOS version has a method called ViewOnUnfocusRequested while the Android's version of the same method is called OnUnfocusRequested.

iOS:

Xamarin.Android Installing APK as System Application

Ideally if you took a Release .apk, anything in the lib/ABI should go into the respective /system/lib folder.

For example with a File->New Android Project

If I created a Release Aligned .apk, I should be able to extract it and view the following:

lib\armeabi-v7a
