title: Decompiler issue "Could not find or load main class classes.dex"
body: <p>Attempting to recover an app I wrote not long ago (do not store in DropBox), I unzipped my .apk and tried to use </p>
  
  <pre><code>d2j-dex2jar classes.dex 
  </code></pre>
  
  <p>to get my source, but got this message instead:</p>
  
  <pre><code>Error: Could not find or load main class classes.dex
  </code></pre>
  
  <p>Like all rookies, my main activity (only one, actually) was named MainActivity.java, not Main.java.  Is this the source of this error and if so, how can I fix it?  If not, what else can I try?</p>
  
  <p>NOTE: this is being done in the DOS cmd window.</p>
  
  <p>EDIT:  wow, nobody has ever seen this?</p>
  
  <p>EDIT: I did not use ProGuard (I checked).</p>
