title: Manually install Gradle and use it in Android Studio
body: <p>I'm using Android Studio. How can I manually install and use <code>Gradle</code> within <code>Android Studio</code>. </p>
  
  <p>I've downloaded <code>Gradle</code> from <a href="http://www.gradle.org/downloads">http://www.gradle.org/downloads</a> version gradle-2.1-all.zip.</p>
  
  <p>When I open the zipped file I can see bin, docs etc, but I don't know where to copy it. And even after copying how to use it within Android..</p>
