Hi, I'm using the component

When I add this component into my Xamarin.iOS project and click compile, and error shows up, I've searched some articles but have no result ...

In iOS device

1st. There is no "" on Google anymore

a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of or, and cannot find, period.
make[1]: *** [] Error 9
make: *** [build-binding] Error 2

is there any other library I can use? or any suggestion of logging into google plus?

    You need to update to latest stable Xamarin.iOS (8.x) in order to use the GooglePlay component.
