Usar a API do Google Places

A resposta pode ser XML ou Json de acordo com o seu pedido. Tudo o que tens de fazer é analisá-lo. Você pode obter lugares à sua volta até 50 kms. Um exemplo para o pedido de url é

https://maps.googleapis.com/maps/api/place/search/xml?location=9.934866,76.267235&radius=50000&types=country%7Cairport%7Camusement_park%7Cbank%7Cbook_store%7Cbus_station%7Ccafe%7Ccar_rental%7Ccar_repair%7Cchurch%7Cdoctor%7Cfire_station%7Cfood%7Chindu_temple%7Chospital%7Clawyer%7Clibrary%7Cmosque%7Cmuseum%7Cpark%7Cparking%7Cpharmacy%7Cpolice%7Cpost_office%7Crestaurant%7Cschool%7Ctrain_station%7Czoo&sensor=true&key=your_API_Key

* Nota: %7C é apenas"|".

Usando o Android Compatível Google APIs Client Library para Java , você pode usar a API do Google Places a partir de uma execução do Android.

O Google coloca API REST está bem documentado. Por exemplo, ao usar a biblioteca cliente APIs do Google para Java e a API do Google Places, confira o seguinte blog entrada:
