        The default behaviour for the Android Maven plugin is to
        attempt to include everything that isn't a class file from every
        dependency jar. Because we already manually included the assets
        and native libraries using the "dependency" plugin above, it's
        necessary to tell the Android Maven plugin to exclude the jar
        files matching the given patterns from the inclusion process.

        This saves roughly 4mb of redundant files from being included
        in the final APK, at the time of writing.
