LibGDX Android setup

So I used LibGDX’s Gradle setup and imported the project into Eclipse. The gdx-setup program seemed to approve my Android SDK. I named it AndroidTest and when I imported it in, in the AndroidTest-android project there were a lot of errors because none of the imports could be recognized. So, I tried getting the ADT plugin for Eclipse and then deleted/re-imported the project, but that didn’t work.

I think it has something to do with this line that is printed in the console whenever I start Eclipse:

[2014-12-31 22:05:23 - AndroidTest-android] Unable to resolve target ‘android-19’

Any ideas?
