First time learning Xamarin, problem when deploying.

After many hours i got everything installed, created an empty app and wanted to see it running. After a whole day searching/trying random suggestions on every corner of the internet i decided to seek help. I have no clue on what is needed to test the android app, tried with an emulator, my nexus and even my tablet.

The picture below show the output log. https://imgur.com/8mOh3iz
