Sample app for the Positronic Net library.
The build procedure, using sbt is something like the following:
First, install the Android SDK, sbt, and the Positronic Net library itself following instructions here.
You'll also need to get your maps API key into the resources, perhaps by putting
a file named apiKey.xml into src/main/res/values, with contents like so:
<resources>
<string name="mapsKey">0xdeadbeef_your_key_goes_here_443543</string>
</resources>
except replacing the content of the mapsKey tag with your actual key.
(Which requires you to have a maps API key; see their docs for details.)
Lastly compile and build this app:
$ cd [your workspace]
$ git clone https://github.com/rst/shopping_assistant.git
$ cd shopping_assistant
$ sbt android:package-debug
If that all worked, you should wind up with an apk in .../shopping_assistant/target/scala_2.8.1/shoppinglists_2.8.1-0.1.apk
