title: Where is the 'dx' tool located in the Android SDK?
body: <p>I have installed the latest Android SDK just now.</p>
  <p>But I can't find the <strong>dx</strong> tool (which is used to convert .class to .dex file). Neither under <code>platform-tool/</code> nor under <code>tools/</code>. Where can I find my <strong>dx</strong> tool then?</p>
  <p>(With Android SDK Manager in Eclipse, I have installed <strong>Android SDK Tools</strong>, <strong>Android SDK Platform Tools</strong>, <strong>Android SDK Build Tools</strong>, and <strong>All the Android platforms</strong> from API 3 to API 19.)</p>
