Compilation
APRSdroid is written in Scala and uses gradle-android-scala-plugin to compile the source. It mostly works, but takes roughly three minutes for a full build, and often produces non-working APKs on incremental builds.
Google Maps: you need to obtain a Maps API key for your signing key, or the map view will remain blank.
Having the Maps API key, do the following to compile and install an APK:
git clone https://github.com/ge0rg/aprsdroid/
cd aprsdroid
git submodule update --init --recursive
# replace AI... with your API key:
echo "mapsApiKey=AI..." > local.properties
# for a debug build:
./gradlew installDebug
# for a release build:
./gradlew installRelease
