Fix viewport information being overwritten.


Geocoder Plus

What is it?

GeocoderPlus is a replacement for the built-in Android Geocoder library. Just like the original, GeocoderPlus geocodes locations -- you enter location names and it returns latitude and longitude coordinates. Unlike the original, GeocoderPlus actually gives you viewport information so you can zoom maps correctly to display entire locations on the screen -- whether those locations are countries, states, cities or buildings.

GeocoderPlus does not include reverse geocoding. You can use the built-in Android Geocoder for reverse geocoding -- no complaints about that functionality.


GeocoderPlus is provided as a JAR library. To add GeocoderPlus to your Android project in Eclipse, follow these steps:

  1. Create a lib directory in your project and copy the GeocoderPlus.jar file there.
  2. Right click on your project in Eclipse and select Properties. This will open the Properties window.
  3. Select Java Build Path from the collapsable options tree on the left. This will show the build path options on the right.
  4. Select the Libraries tab.
  5. Click the Add JARs... button, browse to the lib directory in Step 1 and select the GeocoderPlus.jar file.



To geocode an address, instantiate a new com.bricolsoftconsulting.geocoderplus.Geocoder object, and then call the following function:

List<Address> getFromLocationName(String locationName)

The function will return a list of Address objects. You can get each result address properly formatted using Address.getFormattedAddress(). You can also get the latitude and longitude of an address using Address.getLatitude() and Address.getLongitude(). Finally, you can get the viewport using Address.getViewPort(). There are also additional properties to retrieve each individual address component.

A complete example showing how to use the Geocoder to display locations on a map at the proper zoom factor is provided in the separate GeocoderPlusExample repository at https://github.com/bricolsoftconsulting/GeocoderPlusExample/.


Localization helps you customize the location results based on a particular language and / or region.

Language Localization

GeocoderPlus uses the language in your default Android locale for geocoding. You can manually change the locale either at instantiation via the constructor Geocoder(Locale locale) or after instantiation using the setter Geocoder.setLocale(Locale locale). Make sure you do this before calling the geocoding function.

Region Biasing

GeocoderPlus supports region biasing, which gives priority to certain results based on your location. For example, if you are in the US and have region biasing enabled, searching for Rome will give priority to Rome, GA and Rome, NY at the expense of Rome, Italy which will appear further down in the results.

To enable regions biasing, use the setter Geocoder.setUseRegionBias().
