Doesn't it work out of the box? E.g.
compile 'net.bozho.easycamera:easycamera:0.0.1'

Nope it throws the following

Error:Artifact 'easycamera.jar (net.bozho.easycamera:easycamera:0.0.1)' not found.
Searched in the following locations:
    https://jcenter.bintray.com/net/bozho/easycamera/easycamera/0.0.1/easycamera-0.0.1.jar

and if I precise compile 'net.bozho.easycamera:easycamera:0.0.1@aar' it throws

Error:Artifact 'easycamera.aar (net.bozho.easycamera:easycamera:0.0.1)' not found.
Searched in the following locations:
    https://jcenter.bintray.com/net/bozho/easycamera/easycamera/0.0.1/easycamera-0.0.1.aar

So you should add a easycamera-0.0.1.jar to your repo or rename easycamera-0.0.1-aar.aar to easycamera-0.0.1.aar

Here is a link on how to build a gradle library and publish it to jcenter

Will check

Aha, Maven makes a difference between "classifier" and "type". Could you try something like the thing shown here: http://stackoverflow.com/questions/16682847/how-to-manually-include-external-aar-package-using-new-gradle-android-build-syst e.g. using: ext: "aar" (if it doesn't work, try adding classifier as well)

Ok I tried this compile 'net.bozho.easycamera:easycamera:0.0.1:aar@aar' and it works.
You should add it to you README.md 👍

Done, added to readme. Thanks.
