Quick links:
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:
sudo apt-get install -y git openjdk-8-jdk vim-nox wget unzip
cmdline_tool_file="commandlinetools-linux-6609375_latest.zip"
export ANDROID_SDK_ROOT="$(pwd)/android"
mkdir -p "${ANDROID_SDK_ROOT}"
wget "https://dl.google.com/android/repository/${cmdline_tool_file}"
unzip "${cmdline_tool_file}" -d "${ANDROID_SDK_ROOT}/cmdline-tools"
rm -f "${cmdline_tool_file}"
export PATH="${ANDROID_SDK_ROOT}/cmdline-tools/tools/bin:${PATH}"
export PATH="${ANDROID_SDK_ROOT}/platform-tools:${PATH}"
export PATH="${ANDROID_SDK_ROOT}/emulator:${PATH}"
