Android-Studio: "Gradle is running. Proceed with Project closing?"

Question

I am new and unexperienced to developing Android (Ubuntu 14.04, Android Studio 1.4). I am just trying to solve multiple errors to get my code build, and when I do I get a popup saying

Gradle is running. Proceed with Project closing?

Searching this exact string on google returns 6 hits (most of them from the android developer bugtracking system). Here is a screenshot:

I would like to know what this message means. Will it close the Project when I click 'Yes' (which is not what I want)? What button should I click here?

Answer 1

This message means the gradle is running tasks in background. Sometimes you click 'Yes' stops the tasks. I think this link can be useful for you
