Cordova build android

When I want to try ionic weather app (https://github.com/driftyco/ionic-weather/) I've got problems when I wanted to build android to my phone-gap application using cordova. I receive this message in terminal when I execute the command cordova build android

Error: An error occurred while listing Android targets

I work on ubuntu 13.10

I was able to successfully build the project with the following steps:

npm install -g cordova ionic
git clone https://github.com/driftyco/ionic-weather/
cd ionic-weather
cordova platform add android
cordova build android

You may be missing the required android sdk tools, or they may not have been added to your system path.
