# Versions (modify as needed)
#
# Note: some older gdx versions around 1.9 uses androidx
# which makes dependency resolution more complicated
# It is recommended to use newer versions which is lighter.
#
# Note: I assume box2d, bullet & freetype always have the same version
# as the base libgdx, they probably get updated at the same time
# or so it seems, so I use GDX_VERSION for them rather than
# defining BOX2D_VERSION etc. But correct me if I'm wrong.

JNIGEN_VERSION="2.3.1" # gdx-jnigen-loader

### ---------- Definitions ---------- ###
# All libraries are declared below.
#
# Feel free to remove any architectures you don't want to support
# For example phones normally don't have x86/64 and they are mostly
# used in emulators, you may remove them to save some space.
# arm64 devices can also run armeabi-v7a so that architecture
# should be the bare minimum you need to support.
#
# Simply comment or remove the lines you don't want.
# You can change the versions with the variables on top of the file.
