Android ADT plugin isn't installing on my machine
<p>I've installed the following:</p>

<ul>
<li>JDK </li>
<li>Android SDK</li>
<li>Eclipse Classic 3.7</li>
</ul>

<p>Now I'm trying to install the ADT plugin for eclipse, but in the install process I get the following error:</p>

<pre><code>Cannot complete the install because one or more required items could not be found.
  Software being installed: Android Development Tools 12.0.0.v201106281929-138431 (com.android.ide.eclipse.adt.feature.group 12.0.0.v201106281929-138431)
</code></pre>

<p>How do I go about resolving this error.</p>
