The common (non-UI) parts of libaddressinput are built and run using the Gradle project automation tool:
http://tools.android.com/tech-docs/new-build-system http://www.gradle.org/
Gradle (latest version): https://services.gradle.org/distributions/gradle-2.3-bin.zip
Note: Additionally you must take care to avoid having multiple versions of Gradle on your path, as this can cause problems.
After installing all the prerequisites, check that everything is working by running:
$ gradle build $ gradle test
