Problem from a beginner (starting up a project)

[amirte...@gmail.com]

I am following this tutorial to leran writng android with clojure: https://github.com/alexander-yakushev/events/blob/master/tutorial.md

I have created a new project as mentioned in the tutorial with lein new droid events org.stuff.events :activity MainActivity :target-sdk 15 :app-name EventsListing

I then go forward in the tutorial and connect my smartphone to the laptop, run lein droid doall which produces this bunch of messeges :

Then i open the main.clj file in emacs and run M-x cider, localhost and port 9999 and get this error: nREPL: Direct connection failed.

What am i doing wrong and why it doesnt work? I have Ubuntu 14.04 LTS os.

Hello Amir,

Sorry for the late response. According to the stacktrace, the project failed to build, but the message is not very helpful.

When i try doing lein new droid events org.stuff.events :activity MainActivity :target-sdk 15 :app-name EventsListing, and then immeditely `lein droid doall`, the project builds. Can you try it this way, without changing any versions in project.clj?

Best regards,
Alex
