The app is available on Google Play.
This is the Android version of lucenestudy. It depends on the mobile branch of that project, which in turn comes with prebuilt JARs of Mobile Lucene, an experimental port of Lucene to Android.
To build the app:
git submodule update --init --recursive
./gradlew build
To run lucenestudy's tests on a connected Android device or emulator:
./gradlew connectedAndroidTest
