# This script is meant to run here inside the swig folder
# It's supposed to be a one step build for the java jar and android (.so enclosing) jars (armv7 and x86)
# Output .jar files will be at:
# ../build/libs/${LIBRARY_NAME}-<version>.jar
# ../build/libs/${LIBRARY_NAME}-android-arm-<version>.jar
# remote android-arm build with travis is available at https://s3.amazonaws.com/gubatron-jlibtorrent/release/android/arm64-v8a/libjlibtorrent.so
