It seems that https://jitpack.io is pretty popular now with creating build versions. Essentially you just need to make a release on github and tell people to reference in your gradle file like so
compile 'com.github.glomadrian:dashed-circular-progress:<VERSION_NUM>'
@glomadrian if you are okay with this I can update the README to let people know how to install. You can then just cut a release from master and people can reference it. What do you think?
