Android Studio 8.2 -> IDEA 13.1.3

I created a project in Android Studio 8.2, but was having problems with the signing interface (i.e., nothing is persisted in either the signing or flavors tabs) and found that there seems to be zero support for Android Studio. Not a big deal, as I already own IntelliJ IDEA 13.1 - however, upon attempting to open the project with IDEA I found that I was getting an error about a facet that cannot be loaded 'Java-Gradle'. This missing facet appears to cause any file to show 'Gradle project sync in progress...' at the top of any file you open. I've checked which plugins are installed in each, and the only difference is a Google Cloud Tools for AndroidStudio, and that doesn't appear to be available for IDEA 13.1.

So, are AndroidStudio projects no longer compatible with IDEA? Or is this just a matter of the 8.2 beta being a bit ahead of 13.1.3?
