title: Can't add External Library in Android Studio?
body: <p>I Added a External Library to my project by following 
  <a href="https://stackoverflow.com/questions/20241765/adding-external-library-in-android-studio-0-3-6">this method</a>. and tried this method too <a href="https://stackoverflow.com/questions/16588064/how-do-i-add-a-library-project-to-the-android-studio">this method too</a>.
  Gradle build got Finished and i got this line added to my <code>build.gradle</code> </p>
  
  <pre><code>compile 'com.github.castorflex.smoothprogressbar:library-circular:1.0.1'
  </code></pre>
  
  <p>Now i am trying to <code>import</code> this library in my class. But i can't do this. I took a look at the files and they are located in the build directory under the <code>exploded-aar</code>. so i added <code>@aar</code> to the compile line. Still there are no changes. </p>
  
  <p>How can i import this library to my class or where i am going wrong?   </p>
  
  <p>Thanks in Advance </p>
