Compilation in Maps sample code with Xamarin.Forms

I have got the error below when building the code below:

http://developer.xamarin.com/samples/WorkingWithMaps/

Error 2 Unzipping failed. Please download https://dl-ssl.google.com/android/repository/google_play_services_5089000_r19.zip and extract it to the D:\myStudio\Xamarin\Forms\Controls\Maps\WorkingWithMaps\packages\Xamarin.GooglePlayServices.19.0.0.1\lib\MonoAndroid23\19\content directory. WorkingWithMaps.Android

I unzipped the file following the error message, but got a different compilation error below:
Error 150 "java.exe" exited with code 1. WorkingWithMaps.Android

Any idea?

Thanks in advance.
