Android Open Location Code Demonstrator
2+
=======================================
3+
4+
This is the source code for an Android app that uses
5+
[Open Location Codes](http://openlocationcode.com) and displays them on a map.
6+
7+
It displays the current location, computes the code for that location, and uses
8+
a bundled set of place names to shorten the code to a more convenient form.
9+
Currently all the place names exist within Cape Verde. Other place names can be
10+
added to the source.
11+
12+
Using a bundled set of places means that determining the current address, and
13+
locating an entered address will work offline.
14+
15+
This project has been structured to be used with
16+
[Android Studio](https://developer.android.com/studio/index.html).
17+
18+
An Open Location Code JAR file is in the directory android/libs. If the core library
19+
is updated, you will need to update this JAR file.
