Two Android Manifest file in single location

I am using Fabric plugin and Admob plugin in my project. Both plugin adds Android.Manifest.xml in same location ( Plugins->Android). How do I make the two manifest files to merge properly in final apk. I tried moving one manifest to other folder. Unfortunately, the moved plug in is missed out in the final merge. ( Permissions in moved manifest is not added in final apk). How can I achieve this? Thanks in advance...
