title: Android studio problems with gradle new installation
body: <p>I had some problems with android studio. It fails at compiling time just with some projects (others works fine with same code) because gradle 1.6</p>
  
  <p>I tried something I found on stackoverflow and it started to fail always so I decided to remove android studio folder and download it again.</p>
  
  <p>Now I imported my projects to this new installation and it tells me that my folders are not in gradle and delete them (the folders). SO I cannot do anything.</p>
  
  <p>What do I have to do for deleting all files related to android studio. Grades, plugins... everything. I want to make a clean installation for trying to get everything working without problems.</p>
  
  <p>Should I try IntelliJ Idea instead? What do I have to install for that? Just if it is better than android studio.</p>
