Work space setup to develop mobile app

Hi Friends,

I have tried a lot to create Visual Studio work space to develop mobile application with Xamarin, but failed.

Also i got some suggestion like Java will be the best language to develop Android and Hybrid mobile application.

Please guide me to create any one (Xamarin / Java) of the work space to develop Android / Hybrid application.

Also let me know if any other tool or language will be good to develop such application.

Thanks in advance,

Best Regards,
