title: javax.* cannot be imported in my Android app?
body: <p>I'm trying to import some <code>javax.*</code> classes in my android app, but I keep getting compiler errors inside Android Studio.
  I'm using Ubuntu Linux 13.04.</p>
  
  <p>Here are my imports:</p>
  
  <pre><code>import android.os.Bundle;
  import android.app.Activity;
  import android.view.Menu;
  // Here are the imports I am having trouble with:
  import javax.sound.sampled.AudioFormat;
  import javax.sound.sampled.AudioSystem;
  import javax.sound.sampled.SourceDataLine;
  </code></pre>
  
  <p>And when I try to run the app or even compile the activity java file, I get these errors:</p>
  
  <pre><code>Gradle: error: package javax.sound.sampled does not exist
  Gradle: error: package javax.sound.sampled does not exist
  Gradle: error: package javax.sound.sampled does not exist
  </code></pre>
  
  <p>I just can't figure out this problem. Any help would be awesome!</p>
