# Build Navit for Android.
#
# This script is to be run from the root of the Navit source tree. It is used by CircleCI as well as for local builds,
# in order to keep build environments as uniform as possible and CI test results meaningful.
#
# It will build Navit for all processor architectures specified in navit/android/build.gradle.
#
# When running this script locally, ensure all build dependencies are in place:
# - Packages required: cmake gettext libsaxonb-java librsvg2-bin pkg-config libprotobuf-c-dev protobuf-c-compiler
# - Android SDK installed
# - Environment variable $ANDROID_HOME points to Android SDK install location
# - Android NDK and CMake components installed via
#     sdkmanager ndk-bundle "cmake;3.6.4111459"
#   (later CMake versions from the SDK repository may also work)
#
# If any of the build steps fails, this script aborts with an error immediately.
