title: No source attachment error when debugging Android applications
body: <p>I have just started doing Android development on Mac OS X in Eclipse. When debugging an Activity, I keep getting the following errors:</p>
  
  <blockquote>
    <p>The JAR file /platforms/android-10/android.jar has no source attachment.</p>
  </blockquote>
  
  <p>This is starting to get very annoying, does it mean something is throwing an exception somewhere? (the message itself does not give any meaningful information as to why this is happening) I do not want to step into the source; does Eclipse do this by default? How do I disable it?</p>
