Still not clear.
Do want to get the current location or do you have the current location and you want to get information related to the current location like POI?
if it is the first, have a look at the Android SDK documentation. There are APIs to get the current GPS coordinates and you can do reverse geo-coding to get the street name and so on.
If you are interested in POI;
The only free
POI database that i'm aware of is Google's Places - https://developers.google.com/maps/documentation/places
