Answer 1

You can use OSMBonusPack GeocoderNominatim class.

Answer 2

Here is an example using OSMBonusPack:
// declare your map somewhere in the Activity
map = (MapView) findViewById(R.id.map);
map.setTileSource(TileSourceFactory.MAPNIK);
map.setMultiTouchControls(true);
// create a GeoPoint
final GeoPoint startPoint = new GeoPoint(36.716999, 3.042076);
// Retreive Geocoding data (add this code to an event click listener on a button)
new AsyncTask<Void, Void, Void>(){
#Override
protected Void doInBackground(Void... voids) {
// Reverse Geocoding
GeocoderNominatim geocoder = new GeocoderNominatim(userAgent);
String theAddress;
try {
List<Address> addresses = geocoder.getFromLocation(startPoint.getLatitude(), startPoint.getLongitude(), 1);
StringBuilder sb = new StringBuilder();
if (addresses.size() > 0) {
Address address = addresses.get(0);
int n = address.getMaxAddressLineIndex();
Log.d("Test", "CountryName: " + address.getCountryName());
Log.d("Test", "CountryCode: " + address.getCountryCode());
Log.d("Test", "PostalCode " + address.getPostalCode());
// Log.d("Test", "FeatureName " + address.getFeatureName()); //null
Log.d("Test", "City: " + address.getAdminArea());
Log.d("Test", "Locality: " + address.getLocality());
Log.d("Test", "Premises: " + address.getPremises()); //null
Log.d("Test", "SubAdminArea: " + address.getSubAdminArea());
Log.d("Test", "SubLocality: " + address.getSubLocality());
// Log.d("Test", "SubThoroughfare: " + address.getSubThoroughfare()); //null
// Log.d("Test", "getThoroughfare: " + address.getThoroughfare()); //null
Log.d("Test", "Locale: " + address.getLocale());
for (int i=0; i<=n; i++) {
if (i!=0)
sb.append(", ");
sb.append(address.getAddressLine(i));
}
theAddress = sb.toString();
} else {
theAddress = null;
}
} catch (IOException e) {
theAddress = null;
}
if (theAddress != null) {
Log.d("Test", "Address: " + theAddress);
}
return null;
}
}.execute();
