title: Android Studio build.gradle - Cannot resolve symbol 'android'
body: <p>I've gone through the tutorial <a href="http://developer.android.com/training/index.html">here</a> and everything works except for my build.gradle.  Everything in the 'android' section is is underlined and displays a "Cannot resolve symbol" error message.  This is in Android Studio 0.3.1.  I've even tried re-installing Android Studio and it still doesn't work.</p>
