title: Stuck at 'Gradle project sync in progress...' message in android studio version 1.2.2
body: <p>I am using android studio version 1.2.2 and working on some old project. I keep on getting this message on top of my file as shown in image below, due to which I can't write any code, build apk. I am stuck.
  Also in the background, 'refreshing gradle project' process keeps on working.
  Please help me out of it!
