error in java This element has no attached source and the Javadoc could not be found in the attached Javadoc
<p>I saw in one of my android  project, at the beginning of the file:i have used 
import com.sun.media.sound.Toolkit;</p>

<p>When I hover the mouse on the line <strong>"Toolkit   toolkit = Toolkit.getDefaultToolkit();"</strong> in my code to get more details on this, it shows "<strong>This element has no attached source and the Javadoc could not be found in the attached Javadoc.</strong>" i have even included JRE System Library[JRE6] in my android project...</p>

<p>How to resolve this? Any detailed answer will be appreciated.</p>
