Sorry for the double post, friends. This forum here seems to attract more attention. 
I am new to Xamarim. Just download it couple days ago. I am using the tutorials to get along with the environment as a prospect for an upcoming project. This project will need map support.
After successfully run a few tutorials I got stuck on the FragmentMap one ( http://developer.xamarin.com/guides/android/platform_features/maps_and_location/maps/part_2_-_maps_api/ ). I've been working on this tutorial for about 6 hors with no luck.
The simulator doesn't support KitKat (4.4) so I had to downgrade the framework to Jelly Bean (4.3). The template works fine. But just by adding Google Play Services component for JelyBean without any change to the previously working code breaks the project and it doesn't compile anymore.
The error I am getting is: C:\Users\Armando\Documents\Projects\BrazilianPlan\BrazilianPlan\aapt: Warning: string 'auth_client_needs_installation_title' has no default translation in C:\Users\Armando\AppData\Local\Xamarin\Android.Support.v7.MediaRouter\19.1.0\content\support\v7\mediarouter\res; found: af am ar be bg ca cs da de el en_GB en_IN es es_US et_EE fa fi fr fr_CA hi hr hu hy_AM in it iw ja ka_GE km_KH ko lo_LA lt lv mn_MN ms_MY nb nl pl pt pt_BR pt_PT ro ru sk sl sr sv sw th tl tr uk vi zh_CN zh_HK zh_TW zu (BrazilianPlan)
Actually this is a warning and I get 130 of them. And one error line (red bullet with white X) which is empty (weird).
Has anybody seen this before? What I am doing wrong and how can I get it work?
Thanks in advance.
