Limiting result in country with Google Place autocomplete?

Question

I just tried this demo, but I can't find how to limit result in country. I also checked getAutocompletePredictions in com.google.android.gms.location.places.GeoDataApi, but I can't found any document to implement limiting country.

I also searched some questions in SO; apparently it's JavaScript and needs to add some "optional param". So how to add optional param in this request?

1. you can add the country name in the query , such as "in australia" to limit search in australia

or

2 . add a radius parameter to limit the search
